     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a method for manufacturing a shield harness made by winding a conductive sheet around a periphery of a covered wire and a drain wire. 
     2. Description of the Related Art 
     An automobile as a movable body incorporates various electronic devices and wiring harnesses that supply power from a power source and/or transmitting and receiving control signals sent by microcontrollers and microprocessors to the electronic devices. The wiring harnesses of this kind is for example a shield harness that includes a plurality of covered wires that are bound together, a drain wire, and a shielding layer such as a braid covering the electrical wires and the drain wire, and a coating layer that covers the shielding layer. 
     The covered wire includes an electrically conductive core wire and a cover portion made of insulating synthetic resin that covers the core wire. The drain wire is only constituted by an electrically conductive core wire. The shielding layer such as the braid is formed by braiding electrically conductive strands. The covering layer is made of insulating synthetic resin. 
     As the wiring harness, a shield harness is used that is formed by winding an insulating tape around the periphery of the covered wire, the drain wire, and the shielding layer. 
     The shielding harness is electrically connected to a ground circuit via the drain wire and the shielding layer so that electrical noise that gets into the core wire of the electrical wire from without is reduced or electrical noise inherent in the core wire of the electrical wire is prevented from leaking to an outside. 
     SUMMARY OF THE INVENTION 
     In the shielding harness that has a cover portion that covers the shielding layer, a weight of the cover portion is large, causing a weight of the shield harness as such to increase. In the shield harness that is formed by winding a tape around the periphery of the shielding layer, the shielding layer is easily exposed to an outside, undermining the shielding performance of the shield harness when the tape wound around the periphery of the shielding layer comes off. 
     In view of the above-identified problem, an object of the present invention is to provide a shield harness manufacturing method and device capable of providing a lightweight shield harness having improved shielding performance, the shield harness including an electrical wire, a conductive sheet wound around the electrical wire, and an insulating sheet wound around the conductive sheet that have been wound around the electrical wire. 
     In order to attain the objective, a method for manufacturing a shield harness according to one embodiment of the present invention includes an electrical wire, a conductive sheet covering the covered wire, and an insulating sheet covering the conductive wire, the method including (a) winding the conductive sheet around the electrical wire over a length of the electrical wire with one end of the electrical wire being secured, (b) folding the insulating sheet lengthwise such that the electrical wire and the conductive sheet wound around the electrical wire is placed between two halves of the insulating sheet, (c) winding the folded insulating sheet around the conductive sheet wound around the electrical wire; and (d) welding together one edge of the insulating sheet and the other edge of the insulating sheet over a length of the insulating sheet, with the one edge of the insulating sheet overlapped with the other edge of the insulating sheet over the length of the insulating sheet. 
     In one embodiment of the present invention, the shield harness manufacturing method includes wrapping the bundle of the electrical wires in the conductive sheet using the conductor-winding mold, and then the conductive sheet around the wires are further wrapped in the insulating sheet with the insulator shield folded into substantially two halves using the insulator-winding mold. Accordingly, the shield harness can be manufactured by wrapping the bundle of the electrical wires first in the conductive sheet and then in the insulating sheet. 
     The present invention is capable of manufacturing the shield harness by wounding first the conductive sheet around the periphery of the electrical wire and then winding the insulating sheet around the conductive sheet, eliminating the need of covering the external surface of the conductive sheet by the insulating synthetic resin, shield harness can be made more light-weight, so that the conductive sheet is not exposed to an outside, shielding performance can be improved. 
     Also, the conductor-winding mold wraps the bundle of the electrical wires in the conductive sheet. This means that the readily-plastically-deformed conductive sheet that has been rolled is wound around the periphery of the electrical wires, and accordingly the conductive sheet can be wound more adhesively and in stable contact with the electrical wire. Accordingly, the conductive sheet can be wound around the electrical wire more effectively and securely. 
     Further, the insulating sheet is collapsed by the insulator-winding mold and then wound around the conductive sheet. This means that not-readily-plastically-deformed insulating sheet is collapsed and wound around the periphery of the electrical wire without damage to insulating sheet. Accordingly, the insulating sheet can be wound around the electrical wire and the conductive sheet more effectively and securely. 
     In another embodiment, the present invention provides a method for manufacturing a shield harness including an electrical wire, a conductive sheet covering the covered wire, and first and second insulating sheets covering the conductive wire, the method including (a) winding the conductive sheet around the electrical wire over a length of the electrical wire with one end of the electrical wire being secured, (b) feeding the first insulating sheet and the second insulating sheet such that the electrical wire and the conductive wire wound around the electrical wire are positioned between the first insulating sheet and the second insulating sheet over the length of the electrical wire, (c) wrapping the electrical wire and the conductive sheet wound around the electrical wire in the first and second insulating sheets, and (d) welding together one edge of the first insulating sheet and one edge of the second insulating sheet over a length of the insulating sheets, and welding together the other edge of the first insulating sheet and the other edge of the second insulating sheet over the length of the insulating sheets, with the one edge of the first insulating sheet overlapped with the one edge of the second insulating sheet over the length of the insulating sheets, and with the other edge of the first insulating sheet overlapped with the other edge of the second insulating sheet over the length of the insulating sheets. 
     According to the shield harness manufacturing method with the construction and arrangement described above, the bundle of the electrical wires are wrapped in the conductive sheet using the conductor-winding mold, and then the conductive sheet is wrapped by the insulating sheet sandwiched by the insulator-winding mold. Thus, the shield harness can be manufactured by wrapping the bundle of the electrical wires first in the conductive sheet and then in the insulating sheet. 
     The present invention is capable of manufacturing the shield harness by wounding first the conductive sheet around the periphery of the electrical wire and then winding the insulating sheet around the conductive sheet conductive sheet, which eliminates the need of covering the external surface of the conductive sheet by the insulating synthetic resin, shield harness can be made more light-weight, so that the conductive sheet is not exposed to an outside, shielding performance can be improved. 
     Also, conductive sheet is rolled by the conductor-winding mold and then wound around the electrical wire. This means that readily-plastically-deformed the conductive sheet that has been rolled is wound around the periphery of the electrical wire, more adhesively and in stable contact with the electrical wire. Accordingly, the conductive sheet can be wound around the electrical wire more effectively and securely. 
     Further, the insulator-winding mold sandwiches the conductive sheet and wraps the conductive sheet in the conductive sheet. This means that the electrical wires are wrapped in the not-readily-plastically-deformed insulating sheet, thus the insulating sheet can be wound without causing damage to it. Accordingly, the insulating sheet can be wound around the electrical wire and the conductive sheet more effectively and securely. Further, the both ends in the width direction are welded together over the entire length of the two insulating sheet. Accordingly, the adjustment can be readily achieved by shifting the two welded portion in the width direction of the insulating sheet in response to variation in the number and the diameter of the electrical wires wrapped in the insulating sheet. 
     To address the aforementioned problem, the present invention is also directed to the shield harness manufacturing device according to one embodiment of the present invention includes (a) a conductor-winding mold that winds the electrically conductive sheet around the electrical wire over an entire length thereof, (b) an insulator-winding mold that folds the electrically insulating sheet passed therethrough such that the electrical wire and the conductive sheet wound around the electrical wire is placed lengthwise between two halves of the folded insulating sheet, winds the insulating sheet around the conductive sheet over a length of the conductive sheet, and joins by welding one edge and the other edge of the insulating sheet with the one edge being overlapped with the other edge over a length of the insulating sheet, (c) a sheet feeder that feeds the conductive sheet into the conductor-winding mold so that the conductive sheet is wound around the electrical wire over a length of the electrical wire, and feeds the insulating sheet into the insulator-winding mold so such that the insulator sheet is wound around the conductive sheet over a length of the conductive sheet, (d) an electrical-wire-holding unit that holds one end of an electrical wire that is passed through the conductor-winding mold and the insulator-winding mold, and (e) a control unit that controls manufacturing operation of the shield harness. 
     As it can be understood by the foregoing description, the manufacturing device according to one embodiment of the present invention is capable of manufacturing the shield harness by winding first the conductive sheet around the periphery of the electrical wire and then winding the insulating sheet around the conductive sheet, eliminating the need of covering the external surface of the conductive sheet by insulating synthetic resin and thus making the shield harness more light-weight. The insulating sheet is wound around the external surface of the conductive sheet so that the external surface is not exposed to an outside. In this manner, the shielding performance can be improved. 
     Also, since the conductive sheet that is readily plastically deformed is wound around the periphery of the electrical wire, the conductive sheet can be wound around the electrical wire more adherently and in stable contact with the electrical wire. Accordingly, the conductive sheet can be wound around the electrical wire more effectively. 
     Further, the insulating sheet is folded by the insulator-winding mold and then wound around the conductive sheet by the insulator-winding mold. This means that the insulating sheet that is not readily plastically deformed that has been collapsed is wound around the periphery of the electrical wire and, accordingly, the insulating sheet can be wound without damage around the electrical wire. Accordingly, the insulating sheet can be wound around the periphery of the electrical wire and the conductive sheet more effectively and securely. 
     In another preferred embodiment, the shield harness manufacturing device of the present invention includes the conductor-winding mold that winds the electrically conductive sheet around the electrical wire over a length of the electrical wire, and the insulator-winding mold that places the electrical wire and the conductive sheet wound around the electrical wire lengthwise between a first insulating sheet and a second insulating sheet, wraps the electrical wire and the conductive sheet wound around the electrical wire in the first and second insulating sheets, and welding together one edge of the first insulating sheet and one edge of the second insulating sheet over a length of the insulating sheets, and joins by welding one edge of the first insulating sheet and one edge of the second insulating sheet over the length of the insulating sheets, with the one edge of the first insulating sheet overlapped with the one edge of the second insulating sheet over the length of the insulating sheets, and joins by welding the other edge of the first insulating sheet and the other edge of the second insulating sheet, with the other edge of the first insulating sheet overlapped with the other edge of the second insulating sheet over the length of the insulating sheets. 
     With the construction and arrangement described above, the insulator-winding mold winds the insulating sheet around the conductive sheet that is sandwiched in between. This means that the not-readily-plastically-deformed insulating sheet is wound around the sandwiched electrical wire, and accordingly the insulating sheet can be wound without causing damage to the insulating sheet. Accordingly, the insulating sheet can be wound around the electrical wire and the conductive sheet more effectively and securely. Further, the one edge and the other edge of the insulating sheet is welded together over the entire length of the two insulating sheets. Accordingly, adjustment can be readily achieved by shifting the welded portions in the width direction of the insulating sheet in response to changes in the type and diameter of the electrical wire that are covered by the conductive and insulating sheets. 
     Preferably, the conductor-winding mold includes a main mold and a fastening mold, the main mold has a through-hole through which the electrical wire and the conductive sheet are passed, a diameter of the through-hole gradually decreasing toward downstreamwise in a feeding direction of the conductive and insulating sheets by the sheet feeder, the fastening mold is provided at a downstream edge of the main mold in the feeding direction and is configured to press the electrical wire and the conductive sheet against the main mold. 
     According to the shield harness manufacturing device with the construction and arrangement described above, the electrical wire and the conductive sheet are passed through the through-hole of the main mold of the conductor-winding mold, the diameter of the through-hole gradually decreasing. Accordingly, the conductive sheet can be effectively wound around the electrical wire. 
     Also, the fastening mold sandwiches the electrical wire and the conductive sheet between the fastening mold and the main mold. Accordingly, the shape of the conductive sheet sandwiched between these molds can be adapted to the shape of the electrical wire and facilitating winding of the conductive sheet around the electrical wire. 
     Preferably, the insulator-winding mold includes a main mold and a pair of clamping molds, the main mold receives therein the electrical wire and the conductive sheet, makes the insulating sheet take an U-shaped cross-section, and places the insulating sheet with the U-shaped cross-section at a periphery of the electrical wire and the conductive sheet, and the pair of clamping molds are configured to be moved close to and away from each other such that when the clamping molds are moved close to each other, the one edge and the other edge in the width direction of the insulating sheet are sandwiched by the clamping molds. 
     With the construction and arrangement described above, the main mold of the insulator-winding mold holds therein the insulating sheet such that the U-shaped cross-section is imparted to the insulating sheet, and the one edge and the other edge of the insulating sheet are sandwiched between the pair of clamping mold. Thus, winding of the insulating sheet around the electrical sire and the conductive sheet is facilitated. 
     Preferably, the shield harness manufacturing device of the present invention further includes a fixed unit that holds and joins one edge and the other edge in a width direction of the insulating sheet that is sandwiched between the pair of clamping molds. 
     With the construction and arrangement described above, the fixed unit binds the one edge and the other edge of the insulating sheet, and accordingly the insulating sheet is retained in a state where the insulating sheet is wound around the electrical wire and the conductive sheet. Thus, the insulating sheet can be held in a state where the electrical wires and the conductive sheet are wrapped in the insulating sheet. 
     Preferably, the shield harness manufacturing device of the present invention further includes a movable unit that moves the electrical wire, the conductive sheet, and the insulating sheet in a feeding direction of the conductive and insulating sheets by the sheet feeder. 
     With the construction and arrangement described above, the movable moves the electrical wire, the conductive sheet, and the insulating sheet, which allows the electrical wire, the conductive sheet, and the insulating sheet to be moved with the one edge and the other edge of the insulating sheet bound together by the fixed unit, and accordingly the one edge and the other edge of the insulating sheet can be firmly held over the entire length of the insulating sheet. 
     Conveniently, in the shield harness manufacturing device of the present invention, the electrical wire includes a covered wire that includes a core wire and a cover portion covering the core wire and a drain wire that only includes a core wire, and the electrical-wire-holding unit includes a rotatable holding unit that is rotatable and is configured to hold at its center the covered wire and hold at its peripheral region the drain wire, and the rotatable control unit turns at least one round of rotation in accordance with an instruction by the control unit. 
     The shield harness manufacturing device with the construction and arrangement described above has the rotatable holding unit that is rotated for at least one round of rotation, with the covered wire held at the central region and with the drain wire held at a peripheral region of the rotatable holding unit, thus ensuring that the drain wire is firmly in contact with the conductive sheet, so that the electrical noise can be effectively led via the drain wire to the ground circuit.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The following embodiments are described in order to provide a more precise understanding of a shield harness manufacturing device (hereafter simply called a manufacturing device) of the present invention with reference to  FIGS. 1 to 41 . 
     First Embodiment 
     The manufacturing device according to the first embodiment of the present invention is described below with reference to  FIGS. 1 to 21 . 
     Referring to  FIG. 1 , the manufacturing device  1  is an apparatus that manufactures a shield harness  2  shown in  FIGS. 20 and 21 . The shield harness  2  includes two types of electrical wires, i.e., (a) at least one covered wire  3  (a plurality of covered wires  3  in the embodiments), and (b) a drain wire  4 , (c) an aluminum-laminated sheet  5  (hereafter called an ALS sheet) as a conductive sheet, and (d) a polyethylene terephthalate sheet  6  (hereafter called a PET sheet) as an insulating sheet. 
     The covered wires  3  parallel to each other are bundled together. The covered wire  3  includes a core wire  7  and a cover portion (or sheath) covering the core wire  7 . The core wire  7  may be one single wire or made of conductor strands that are twisted together. The core wire  7  has a circular cross-section. The conductor strands of the core wire  7  are made of electrically conductive metal. The core wire  7  is flexible and the cover portion  8  covering the core wire  7  is made of electrically insulating synthetic resin and also flexible. 
     The drain wire  4  is only constituted by a core wire  9  made of electrically conductive metal. The core wire  9 , in a similar manner as in the core wire  7  of the covered wire  3 , may be one single wire or made of wire strands that are twisted together. 
     As shown in  FIG. 21 , the core wire  9  has a circular cross-section. The drain wire  4  as viewed in cross-section is not surrounded by the plurality of covered wires  3 : The drain wire  4  is disposed between the two covered wires  3  and the ALS sheet  5  at a peripheral region, i.e., a region radially outward of the central region of the shield harness  2 . The significance of this arrangement of the drain wire  4  will be explained later. 
     The ALS sheet  5  is a thin sheet or strip that includes a thin conductive layer  10  and a thin insulating layer  11  laminated upon the conductive layer  10 . The conductive layer  10  is made of electrically conductive metal having flexibility. The conductive layer  10  includes at least aluminum or aluminum alloy. The insulating layer  11  is made of electrically insulating synthetic resin having flexibility. 
     The ALS sheet  5  is wound around a wire bundle, i.e., the covered wires  3  and the drain wire  4  that are bundled in the above-described manner (without use of a tape that is wound around a portion of the wires). As shown in  FIG. 21 , the ALS sheet  5  is wound with the conductive layer  10  inside, i.e., always facing the center of the shield harness  2 , and with the conductive layer outside, or more specifically, such that the conductive layer  11  that is being wound always comes into contact with the insulating layer  11  that has already been wound, so that winding of the ALS sheet is finished with the insulating layer  11  constituting an outer surface of the ALS-wound wire bundle. In addition, as shown in  FIG. 21 , the conductive layer  10  of the ALS sheet  5  is in contact with an outer surface of the drain wire  4  at the peripheral region of the shield harness  2 . 
     The PET sheet  6  is a thin sheet (or a strip) made of electrically insulating synthetic resin having flexibility such as polyethylene terephthalate. 
     The shield harness  2  is manufactured by (a) bundling together the covered wires  3  and the drain wire  4  into the wire bundle such that the drain wire  4  is not surrounded by the covered wires  3  but placed outermost of the bundled wires, (b) winding the ALS sheet  5  around the wire bundle with the conductive layer  10  coming inside, and then (c) wrapping the ALS-wound wire bundle in the PET sheet  6 . The ALS sheet and the PET sheet  6  are in parallel with the covered wires  3  and the drain wire  4  lengthwise of the shield harness  2 . The ALS sheet is wound around the bundle of the covered wires  3  and the drain wire  4 , and the ALS-wound wire bundle is wrapped in the PET sheet  6 , with the one edge  6   a  and the other edge  6   b  lengthwise of the PET sheet  6  are brought into contact with each other over the entire length of the PET sheet  6 , and the two edges  6   a  and  6   b  are joined together by welding to form a joint over the entire length of the PET sheet  6 . This is a brief overview of how the shield harness  2  according to the first embodiment of the present invention is manufactured. 
     Further, a terminal fitting  12  (partially illustrated in  FIG. 15B ) and a connector housing (not shown) are attached to one end and the other end of the covered wires  3  and the drain wire  4  of the shield harness and then the terminal fittings  12  is received in a connecter housing in a known manner, attached, inserted, or connected into a connector housing (not shown). Further, the connector housing connected to the shield harness  2  is connected to an automotive electronic device to transmit and receive signals to and from the device and/or supply power to the devices. 
     Further, the conductive layer  10  of the ALS sheet of the shield harness  2  is connected via the drain wire  4  to a ground circuit so that external electrical noise entering the core wire  7  of the covered wire  3  and electrical noise going out of the core wire  7  of the covered wire  3  are led via the conductive layer  8  of the ALS sheet  5  and the drain wire  4  to the ground circuit. 
     The manufacturing device  1  is an apparatus that winds the ALS sheet around the bundle of the covered wires  3  and the drain wire  4  that have been cut in a predetermined length and with terminal fittings  12  attached to the one end and the other end thereof, and then wrap the ALS-wound wire bundle in the PET sheet  6  so that the ALS sheet  5  is covered by the PET sheet  6 .

When the movable pulley  53  is moved close to the lower fixed pulley  52  of the pair of fixed pulleys  52 , the PET sheet  6  is fed. 
     The multiple-component-type guide  42  is provided near the sheet feeder  41  and closer to the movable holding unit  25  than the sheet feeder  41  is. As shown in  FIG. 6A , the multiple-component-type guide  42  has a columnar guide body  54  and a cover  55 . 
     The guide body  54  is formed in a shape of a quadratic prism that upstands from the body  13  of the manufacturing device  1 . An ALS-guide hole  56  and a PET-guide hole  57  extend through the guide body  54 . The ALS-guide hole  56  is provided at the heightwise centre of the guide body  54 , and extends over the length of the guide body  54  in the longitudinal direction of the body  13  of the manufacturing device  1 . The ALS-guide hole  56  has a V-shaped cross-section. The ALS sheet  5  is passed through the ALS-guide hole  56 . Note that the term “heightwise centre” does not refer to  FIG. 1  but it is only specific to the illustration of  FIG. 6 . 
     The PET-guide hole  57  is provided lower than the heightwise centre of the guide body  54  and extends through the guide body  54  in the longitudinal direction of the body  13  of the manufacturing device  1 . The PET-guide hole  57  has a V-shaped cross-section. The valley of the PET-guide hole  57  is less acute-angled than that of the ALS-guide hole  56 . The PET sheet  6  is passed through the PET-guide hole  57 . 
     Also, the guide body  54  has an electrical-wire-guiding groove  58 . The electrical-wire-guiding groove  58  is formed concave on the upper surface of the guide body  54 , and extends straight in the longitudinal direction of the body  13  of the manufacturing device  1 . The electrical-wire-guiding groove  58  has a V-shaped cross-section. The valley of the electrical-wire-guiding groove  58  is more acute-angled than that of the ALS-guide hole  56  (and accordingly that of the PET-guide hole  57 ). The covered wires  3  and the drain wire  4  are passed through the electrical-wire-guiding groove  58 . 
     The cover  55  is formed in a shape of a thick flat plate. The cover  55  is mounted on the upper end of the columnar guide body  54  to be pivotable about an axis between a closed position where the electrical-wire-guiding groove  58  is closed by the cover  55  and an open position where the top of the electrical-wire-guiding groove  58  is wide open. 
     The sliding blade  43  is formed in a shape of a strip. The sliding blade  43  is superposed on a lateral surface of the guide body  54  of the multiple-component-type guide  42 , the lateral surface facing the movable holding unit  25 , and configured to be slidable in a vertical direction. The sliding blade  43  has a guide hole that registers with the ALS-guide hole  56  and the PET g 57  so that the ALS sheet  5  and PET sheet  6  are passed therethrough. The sliding blade  43  is slid relative to the guide body  54  in the vertical direction, so that the ALS sheet  5  and the PET sheet  6  are cut by the sliding blade  43  on the lateral surface of the guide body  54 . 
     The conductor-winding unit  18  is provided near the multiple-component-type guide  42  and closer to the movable holding unit  25  than the multiple-component-type guide  42  is. As shown in  FIG. 1 , the conductor-winding unit  18  has a conductor-winding mold  59  and a cylinder unit (not shown). 
     Referring to  FIG. 7A , the conductor-winding mold  59  has a main mold  60  and a fastening mold  61 . The main mold  60  has a lower mold  62  and an upper mold  63  on top of lower mold  62  in a vertical direction, both of which are formed in a shape of a thick flat plate. The lower mold  62  and the upper mold  63  can be moved, in the vertical direction, close to each other (until finally in contact with each other) and away from each other so as to be detached from each other. 
     The lower mold  62  and the upper mold  63  defines a through-hole  64  therebetween, through which the covered wires  3  and the ALS sheet  5  covering the covered wires  3  are passed. The through-hole  64  is constituted by two concave grooves facing each other, i.e., a concave groove formed on a surface of the lower mold  62  and a concave groove formed on a surface of the upper mold  63  that comes into contact with the surface of the lower mold  62 . The through-hole  64  is a round hole whose diameter decreases gradually from the side of the multiple-component-type guide  42  toward the side of the movable holding unit  25  while the lower mold  62  and the upper mold  63  are in contact with each other. This means that the diameter of the through-hole  64  decreases gradually toward a downstream region in a feeding direction of the sheet feeder  41 . The covered wires  3  and the ALS sheet  5  positioned around the covered wires  3  are passed through the through-hole  64  as the lower mold  62  and the upper mold  63  are moved close to each other, and thus the ALS sheet  5  is wound around the covered wires  3 . 
     The fastening mold  61 , as shown in  FIG. 7B , is mounted on an end of the upper mold  63  of the main mold  60 , the end being closer to the movable holding unit  25  (a rightmost end of the main mold  60  in the feeding direction of the ALS sheet  5  and PET sheet  6  by the sheet feeder  41 ). The fastening mold  61  is mounted on the upper mold  63  slidably in the vertical direction. When the fastening mold  61  is moved close to the lower mold  62 , the covered wires  3 , the drain wire  4 , and the ALS sheet  5  wound around these wires are sandwiched between the fastening mold  61  and the lower mold  62 . 
     The cylinder unit moves these molds  62 ,  63 , and  64  in the vertical direction so that the molds  62 ,  63 , and  64  are moved close to and away from each other. 
     The insulator-winding unit  19  is provided near the conductor-winding unit  18  and closer to the movable holding unit  25  than the conductor-winding unit  18  is. As shown in  FIG. 1 , the insulator-winding unit  19  has an insulator-winding mold  65  and a shifting unit (not shown). 
     Referring to  FIG. 10A , the insulator-winding mold  65  has a main mold  66  and a pair of clamping molds  67 . As shown in  FIG. 10A  and also in  FIG. 10B , the main mold  66  includes one bottom mold  68  and a pair of guide molds  69 . The bottom mold  68  has a body  70  formed in a shape of a thick flat plate and a wire-rest portion  71  that protrudes from an upper surface of the body  70 . The wire-rest portion  71  extends in a linear fashion lengthwise of the body  13  of the manufacturing device  1  and provided over the entire length of the body  70 . The upper surface of the wire-rest portion  71  has a concave upper surface with an arc-shaped cross section. Also, the wire-rest portion  71  can be slid relative to the pair of guide molds  69  in the vertical direction. 
     The pair of guide molds  69  are spaced from each other in the width direction of the body  13  of the manufacturing device  1 , and the wire-rest portion  71  of the bottom mold  68  is positioned between the guide molds  69  in the width direction. The surfaces of the guide molds  69  facing each other is formed flat in the vertical direction and in the longitudinal direction of the body  13  of the manufacturing device  1 . With the guide mold  69  moved down, the surface of the guide mold  69  and the upper surface of the wire-rest portion  71  of the bottom mold  68  together takes a U-shaped cross-section. 
     The bottom mold  68  and the pair of guide molds  69  can be integrally raised and lowered. Also, the main mold  66 , while in a state where the bottom mold  68  is lowered relative to the guide molds  69 , places the PET sheet  6 , which is positioned at a periphery of the ALS-wound wire bundle, on the upper surface of the wire-rest portion  71  of the bottom mold  68 , and places the PET surface  6  between the surfaces of the pair of guide molds  69  opposed to each other. Thus, the body  70  makes the PET sheet  6  that is positioned at the periphery of the ALS-wound wire bundle take a U-shaped cross-section. 
     The pair of clamping molds  67  are each formed in a shape of a strip extending in a linear fashion lengthwise of the body  13  of the manufacturing device  1  and are spaced from each other in the width direction of the body  13  of the manufacturing device  1 . Also, the pair of clamping molds  67  are provided above the main mold  66  and can be moved close to and away from (raised or lowered with respect to) the main mold  66 . The pair of clamping molds  67  are together moved close to the main mold  66  and also close to each other so as to sandwich the one edge  6   a  and the other edge  6   b  of the PET sheet  6  provided on the main mold  66 . 
     The shifting unit moves the main mold  66  and the pair of clamping molds  67  integrally in the width direction of the body  13  of the manufacturing device  1 . The main mold  66  and the pair of clamping molds  67  can be moved in the longitudinal direction of the body  13  of the manufacturing device  1  from a position where they are closely aligned with the main mold  60  and fastening mold  61  of the conductor-winding unit  18  to a position where they are not closely aligned with these molds  60  and  61 . 
     Also, the shifting unit raises and lowers the bottom mold  68  and the pair of guide mold  69  of the main mold  66  integrally, and raises and lowers the pair of clamping molds  67  integrally. Further, the shifting unit raises and lowers the bottom mold  68  relative to the guide mold  69  of the main mold  66 , and makes the pair of guide molds  69  move close to and away from each other. 
     The fixed unit  20  is provided near the insulator-winding unit  19  and closer to the movable holding unit  25  than the insulator-winding unit  19  is. As shown in  FIG. 14 , the fixed unit  20  has a horn  72  and an anvil  73  that are moved close to and away from each other, a piezoelectric vibrator (not shown) that brings the horn  72  into ultrasonic vibration, and a cylinder unit (not shown) that makes the horn  72  and the anvil  73  move close to and away from each other. 
     The horn  72  and the anvil  73  are spaced from each other in the width direction of the body  13  of the manufacturing device  1 . The horn  72  and the anvil  73  are each configured in a form of a strip lengthwise parallel to the width of the body  13  of the manufacturing device  1 . The piezoelectric vibrator makes the horn  72  vibrate with small amplitude at a frequency of for example 20 KHz. 
     The cylinder of the fixed unit  20  moves the horn  72  and the anvil  73  close to each other, so that the one edge  6   a  and the other edge  6   b  widthwise of the PET sheet  6  is sandwiched between the horn  72  and the anvil  73 . The piezoelectric vibrator causes ultrasonic vibration of the horn  72 , and frictional heat occurs at the one edge  6   a  and the other edge  6   b  of the PET sheet  6 , so that the one edge  6   a  and the other edge  6   b  are joined together by welding. 
     The movable unit  21  is provided at a region more distant from the feeders  14  and  15  than the fixed unit  20  is. The movable unit  21  has a pair of belt units  74  that are spaced from each other and moved close to and away from each other in the width direction of the body  13  of the manufacturing device  1  and a cylinder unit (not shown) that makes the belt units  74  move close to and away from each other. Each of the belt units  74  has a driving pulley that is driven by a motor, a rotatable driven pulley spaced from the driving pulley, and an endless belt provided around the pulleys. The belt unit  74 , via the rotation of the driving pulley, runs the endless belt around the pulleys. The movable unit  21  moves the pair of belt units  74  close to each other and makes the belt units  74  sandwich the ALS-wound wire bundle and the PET sheet  6  covering the ALS-wound wire bundle, with the endless belt of the belt unit  74  running, the ALS-wound wire bundle and the PET sheet  6  covering the ALS-wound wire bundle are moved in the longitudinal direction. This means that the movable unit  21  moves the ALS-wound wire bundle and the PET sheet  6  covering the ALS-wound wire bundle in the feeding direction of the ALS and PET sheets  5 ,  6  by the sheet feeder  41 . 
     The control unit  22  is a microcontroller (or microprocessor) incorporating a known read-only memory (ROM) unit, a random access memory (RAM) unit, and a central processing unit (CPU). The control unit  22 , which controls the entire functionality and operation of the manufacturing device  1 , is connected to and controls the electrical-wire-holding unit  16 , the guide unit  17 , the conductor-winding unit  18 , the insulator-winding unit  19 , the fixed unit  20 , and the movable unit  21 . 
     The control unit  22  stores information including an interval at which the ALS sheet  5  and the PET sheet  6  are cut. The control unit  22 , on the basis of the stored information, controls the carrier cylinder and chuck portions  29  and  30  of the movable holding unit  25  of the electrical-wire-holding unit  16 , the motor of the rotatable holding unit  26 , the sheet feeder  41  of the guide unit  17 , the cylinder unit of the conductor-winding unit  18 , the movable unit of the insulator-winding unit  19 , the piezoelectric vibrator and the cylinder unit of the fixed unit  20 , and the motors of the belt units  74  of the movable unit  21 , and winds the ALS sheet  5  around the covered wires  3  and the drain wire  4  that have been cut in a predetermined length with the terminal fitting  12  attached to both ends of the wires  3  and  4 , and then wraps the ALS-wound wire bundle in the PET sheet  6 , and joins by welding the one edge  6   a  and the other edge  6   b  of the PET sheet  6 . 
     It should be noted that the each steps of the manufacturing method achieved by the manufacturing device  1  is controlled by the control unit  22 . Accordingly, even when not explicitly recited in the following sections, each functional units of the manufacturing device dedicated to a specific action is controlled by the instruction of the control unit  22 . 
     Having fully described the construction and arrangement of the manufacturing device  1  according to the first embodiment, the following describes how the shield harness  2  is manufactured by the manufacturing device  1  by applying first the ALS sheet  5  and then the PET sheet  6  around the covered wires  3  and the drain wire  4  that are cut in the predetermined length with the terminal fittings  12  attached to the both end thereof. 
     As preparatory operation, the terminal fitting  12  has to be attached to one end of the covered wires  3  and the drain wire  4 . Then the covered wires  3  and the drain wire  4  are hooked onto the terminal holder  28  of the movable holding unit  25  of the electrical-wire-holding unit  16 , and then the one end of the covered wires  3  and the drain wire  4  is held by the terminal holder  28 . Meanwhile, the other end of the covered wire  3  is inserted into the electrical-wire-holding slit  38  of the driven gear  37  of the rotatable holding unit  26  such that the other end of the covered wires  3  are held. Likewise, the other end of the drain wire  4  is inserted into the drain-wire-holding slit  39  of the driven gear  37  of the rotatable holding unit  26  so that the other end is held. Further, the central portion of the covered wires  3  and the drain wire  4  is received in the electrical-wire-guiding groove  58  of the multiple-component-type guide  42  of the guide unit  17 , and the opening of the electrical-wire-guiding groove  58  is closed by the cover  55 . 
     Further, the tip of the ALS sheet  5  wound around the reel  23  of the ALS feeder  14  is passed through the guide hole  47  of the ALS-guide  44  of the fixed guide  40  of the guide unit  17  and then between the fixed pulley  52  provided at an upper portion of the sheet feeder  41  and the movable pulley  53  provided at a central portion of the sheet feeder  41 , and further into the ALS-guide hole  56  formed on the columnar guide body  54  of the multiple-component-type guide  42  so as to be in contact with the sliding blade  43 . 
     Also, the tip of the PET sheet  6  wound around the reel  24  of the PET feeder  15  is passed (in order of appearance below) through the guide hole  48  of the first PET-guide  45  of the fixed guide  40  of the guide unit  17 , between the guide rollers  50  of the second PET-guide  46 , and between the fixed pulley  52  provided at a lower portion of the sheet feeder  41  and the movable pulley  53  of the sheet feeder  41 . The tip of the PET sheet  6  is inserted into the PET-guide hole  57  provided on the columnar guide body  54  of the multiple-component-type guide  42  so as to be in contact with the sliding blade  43 . 
     Upon completion of the preparatory operation, the manufacturing device  1  is now ready to start manufacturing operation. 
     The movable pulley  53  at the upper portion of the sheet feeder  41  is moved close to the fixed pulley  52 , and, as shown in  FIG. 5B , the pulleys  52  and  53  sandwich the ALS sheet  5  between them. The sliding blade  43  is placed at a position where the guide hole of the sliding blade  43  registers with and communicates with the guide holes  56  and  57  of the multiple-component-type guide  42  (shown in  FIG. 6A ). As shown in  FIGS. 7A and 7C , the lower mold  62  and the upper mold  63  of the conductor-winding unit  18  move away from each other, and the fastening mold  61  is moved away from the lower mold  62 . The covered wires  3  and the drain wire  4  is placed between the upper mold  63  and the lower mold  62 . 
     The main mold  66  and the pair of clamping molds  67  of the insulator-winding unit  19  are placed all together at a position where they are not closely aligned with the conductor-winding unit  18  in the longitudinal direction of the body  13  of the manufacturing device  1 . As shown in  FIG. 10A , the main mold  66  and the pair of clamping molds  67  of the insulator-winding unit  19  are moved away from each other, and the bottom mold  68  is lowered relative to the pair of guide molds  69 . The pair of clamping molds  67  are spaced away from each other. 
     As shown in  FIG. 16 , the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) are placed most proximate to the conductor-winding unit  18 , and the pair of chuck members  33  of the electrical-wire-chuck portion  29  are moved close to each other, so that the covered wires  3  and the drain wire  4  are sandwiched between them. Further, as shown in  FIG. 13A , the pair of chuck members  34  of the sheet-chuck portion  30  are spaced from each other. The pair of belt units  74  of the movable unit  21  are also spaced from each other, and the horn  72  and the anvil  73  of the fixed unit  20  are spaced from each other. 
     Next, as shown in  FIGS. 8A and 8C , the upper mold  63  and the lower mold  62  of the conductor-winding unit  18  are placed in direct contact with each other, so that the covered wires  3  and the drain wire  4  are sandwiched between the molds  62  and  63 . Thus, the covered wires  3  and the drain wire  4  are passed through the conductor-winding mold  59 . 
     After that, the motor (not shown) drives and rotates the movable pulley  53  of the sheet feeder  41 , so that the ALS sheet  5  is fed into the through-hole  64  of the main mold  60  of the conductor-winding mold  59  of the conductor-winding unit  18 . Since the diameter of the through-hole  64  gradually decreases toward the side of movable holding unit  25 , the ALS sheet  5  is guided by the inner surface of the through-hole  64  (see  FIG. 8B ), and gradually wound around the wire bundle (i.e., the covered wire  3  and the drain wire  4 ). 
     When the tip of the ALS sheet  5  is passed through the through-hole  64  and placed between the pair of chuck members  34  of the sheet-chuck portion  30  (see  FIG. 13B ), the movable pulley  53  of the sheet feeder  41  stops rotating and the pair of chuck members  34  of the sheet-chuck portion  30  move close to each other (see  FIG. 13C ), and thus the tip of the covered wires  3 , the drain wire  4 , and the ALS sheet  5  is sandwiched between the chuck members  34 . 
     Following this, as shown in  FIGS. 9A and 9C , the fastening mold  61  of the conductor-winding mold  59  is lowered and the tip of the covered wires  3 , the drain wire, and the ALS sheet  5  is sandwiched between the fastening mold  61  and the lower mold  62 . After that, as shown in  FIG. 9B , the ALS sheet  5  is wound around the wire bundle so that the wire bundle and the ALS sheet  5  is in intimate contact with each other. 
     After that, the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is moved away from the conductor-winding unit  18 . Further, the insulator-winding mold  65  is moved along with the movable unit  21  of the insulator-winding unit  19 , so that the insulator-winding mold  65  is placed at a position where the insulator-winding mold  65  is closely aligned with the conductor-winding mold  59  of the conductor-winding unit  18  in the longitudinal direction of the body  13  of the manufacturing device  1 . In this manner, as shown in  FIG. 17 , the insulator-winding unit  19  is placed between the conductor-winding unit  18  and the movable holding unit  25 . Thereafter, as shown in  FIG. 13D , the pair of chuck members  34  of the sheet-chuck portion  30  are moved away from each other and the movable pulley  53  provided at the lower portion of the sheet feeder  41  of the guide unit  17  is moved close to the fixed pulley  52 , so that the PET sheet  6  is sandwiched between the pulleys  52  and  53 . 
     Thereafter, the movable pulley  53  of the sheet feeder  41  is driven by the motor (not shown) and rotated, so that the PET sheet  6  is fed onto the upper surface of the wire-rest portion  71  of the bottom mold  68  of the main mold  66  of the insulator-winding mold  65  of the insulator-winding unit  19  shown in  FIG. 10A . Since the U-shaped cross-section is defined by the upper surface of the wire-rest portion  71  of the bottom mold  68  and the surface of the two guide molds  69 , the PET sheet  6  is guided by the upper surface of the wire-rest portion  71  and the surface of the pair of guide mold  69 . As shown in  FIGS. 10B and 10C , the PET sheet  6  is folded into substantially two halves and is disposed around the ALS-wound wire bundle. 
     Following this, the pair of clamping molds  67  are lowered, and, as shown in  FIG. 10B , the pair of clamping molds  67  are placed very close to (but not in direct contact with) the pair of guide molds  69  of the main mold  66 . 
     After that, when the tip of the PET sheet  6  rests upon the wire-rest portion  71  and is passed between the pair of guide molds  69 , and, as shown in  FIG. 13E , is placed between the pair of chuck members  34  of the sheet-chuck portion  30 , then the movable pulley  53  of the sheet feeder  41  stops rotating and the pair of chuck members  34  of the sheet-chuck portion  30  are moved close to each other. Further, as shown in  FIG. 13F , the tip of the covered wires  3 , the drain wire  4 , the ALS sheet  5 , and the PET sheet  6  is sandwiched between the chuck members  34 , and, as shown in  FIG. 11A , the pair of clamping molds  67  of the insulator-winding unit  19  are moved close to each other so that the one edge  6   a  and the other edge  6   b  of the PET sheet  6  are sandwiched between the pair of clamping molds  67 . Then, as shown in  FIG. 11B , the PET sheet  6  is folded into substantially two halves and covers therein the bundle of the covered wires  3 , the drain wire  4 , and the ALS sheet  5 , so that the one edge  6   a  and the other edge  6   b  of the PET sheet  6  comes in close contact with each other. 
     Thereafter, as shown in  FIG. 12A , the bottom mold  68  of the insulator-winding unit  19  is raised and the tip of the covered wires  3 , the drain wire  4 , the ALS sheet  5 , and the PET sheet  6  is sandwiched between the bottom mold  68  and the pair of clamping molds  67 . After that, as shown in  FIG. 12B , the PET sheet  6  is folded into substantially two halves, covering the ALS-wound wire bundle such that the ALS-wound wire bundle and the PET sheet  6  are in intimate contact with each other. 
     Following this, as shown in  FIG. 14 , the horn  72  and the anvil  73  of the fixed unit  20  are moved close to each other so that the one edge  6   a  and the other edge  6   b  of the PET sheet  6  is clamped between the horn  72  and the anvil  73  with the horn  72  under ultrasonic vibration by the ultrasonic oscillator. Then, frictional heat occurs at portions of the one edge  6   a  and the other edge  6   b  of the PET sheet  6  that are clamped between the horn  72  and the anvil  73  and, as a result, the two ends  6   a  and  6   b  of the PET sheet  6  are welded together. Thereafter, the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is moved away from the conductor-winding unit  18 . As the movable holding unit  25  is moving, the covered wires  3 , the drain wire  4 , the ALS sheet  5 , and the PET sheet  6  are moved away from the conductor-winding unit  18 , and the portions of the one edge  6   a  and the other edge  6   b  of the PET sheet  6  that are clamped between the horn  72  and the anvil  73  are also moved, and as a result the one edge  6   a  and the other edge  6   b  of the PET sheet  6  are welded in the longitudinal direction in response to movement relative to the conductor-winding unit  18 . 
     After that, when, as shown in  FIG. 18 , the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is placed at a position more distant from the rotatable holding unit  26  than the pair of belt units  74  of the movable unit  21  is, then the slider  32  stops moving. Thereafter, the pair of belt units  74  of the movable unit  21  are moved close to each other, so that the PET sheet  6  wound around the ALS-wound wire bundle is sandwiched between the belt units  74 . Also, the pair of chuck member  33  of the electrical-wire-chuck portion  29  are moved away from each other, and the pair of chuck members  34  of the sheet-chuck portion  30  are moved away from each other, and the driving pulley of the belt unit  74  of the movable unit  21  is rotated. Further, the covered wires  3 , the drain wire  4 , and the ALS sheet  5 , and the PET sheet  6  are moved all together away from the feeders  14  and  15 . 
     Thereafter, when the ALS sheet  5  and the PET sheet  6  are moved for a predetermined distance, as shown in  FIG. 6C , the sliding blade  43  slides relative to the guide body  54  of the multiple-component-type guide  42 , and cuts the ALS sheet  5  and the PET sheet  6 , and, immediately before sliding of the sliding blade  43  and accordingly immediately before cutting of the ALS sheet  5  and the PET sheet  6 , the motor of the rotatable holding unit  26  is driven to cause only one round of rotation of the driven gear  37 . After that, since the other end of the drain wire  4  is held at a periphery of the driven gear  37 , the drain wire  4  is positioned at a peripheral region of the circular cross section of the wire bundle, and comes into direct contact with the conductive layer  10  of the ALS sheet  5 . Thus, the rotatable holding unit  26  of the electrical-wire-holding unit  16  controlled by the control unit  22  causes at least one round of rotation of the driven gear  37 . 
     Following this, the sliding blade  43  slides again, and places the sliding blade  43  at a position where the guide hole of the sliding blade  43  registers with the guide holes  56  and  57  of the multiple-component-type guide  42 , and the endless belt of the belt unit  74  of the movable unit  21  runs so that the ALS-wound wire bundle including the covered wires  3  and the drain wire  4  and the PET sheet  6  covering the ALS-wound wire bundle are moved to a position more distant from the feeders  14  and  15  than the movable holding unit  25  is. 
     The manufacturing of the shield harness  2  is thus completed. 
     The shield harness manufacturing device and the shield harness manufacturing method according to the first embodiment of the present invention have the following advantages. 
     The conductor-winding mold  59  is provided to wind the ALS sheet  5  around the wire bundle constituted by the covered wires  3  and the drain wire  4 , and the insulator-winding mold  65  is provided to wind the PET sheet  6  around the ALS sheet  5  that has been wound around the wire bundle. Thus, the shield harness  2  is manufactured by winding first the ALS sheet  5  and then the PET sheet  6  around the bundle of the covered wires  3  and the drain wire  4 . 
     Accordingly, the shield harness  2  can be made more light-weight since the need of covering the external surface of the ALS sheet  5  by an insulating synthetic resin is eliminated. Also, since the PET sheet  6  covers the external surface of the ALS sheet  5 , the ALS sheet  5  wound around the wire bundle can be protected against being exposed to an outside, and thus shielding performance of the shield harness  2  can be improved. 
     Also, since the ALS sheet  5  that is wound around the wire bundle by the conductor-winding mold  59  is readily plastically deformed the ALS sheet  5  can be wound more adhesively and in more stable contact with the covered wire  3  and the drain wire  4 . Accordingly, the ALS sheet  5  can be wound around the wire bundle effectively. 
     Further, the insulator-winding mold  65  folds the PET sheet  6  into substantially two halves and wraps the ALS-wound wire bundle in the folded PET sheet  6 . Since the PET sheet  6  that is not readily plastically deformed is folded into substantially two halves and wound around the ALS-wound wire bundle, the PET sheet  6  can be wound without causing damage to the PET sheet  6 . Thus, the not-readily-plastically-deformed PET sheet  6  can be effectively wound around the ALS-wound wire bundle. 
     Since the covered wires  3 , the drain wire  4 , and the ALS sheet  5  are inserted into the through-hole  64  of the main mold  60  of the conductor-winding mold  59 , the diameter of the through-hole  64  gradually decreasing, the ALS sheet  5  can be effectively wound around the wire bundle. 
     In addition, since the ALS sheet  5  is sandwiched between the fastening mold  61  and the main mold  60 , the wound ALS sheet  5  is clamped between the two molds so that the ALS sheet  5  can be snugly wound around the wire bundle. 
     Since the main mold  66  of the insulator-winding mold  65  holds the PET sheet  6  in such a manner that the cross-section of the PET sheet  6  takes an U-shape and the one edge  6   a  and the other edge  6   b  of the PET sheet  6  are clamped between the pair of clamping molds  67 , the PET sheet  6  can be wound around the ALS-wound wire bundle with the PET sheet  6  folded substantially into two halves. 
     Since the one edge  6   a  and the other edge  6   b  of the PET sheet  6  are joined with each other by the fixed unit  20 , the two edges of the PET sheet  6  can be joined together with the PET sheet  6  wound around the covered wires  3 , the drain wire  4 , and the ALS sheet  5 . 
     By virtue of the moving unit  21  that carries the covered wires  3 , the drain wire  4 , the ALS sheet  5 , and the PET sheet  6 , the ALS-wound wire bundle covered by the PET sheet  6  can be moved with the one edge  6   a  and the other edge  6   b  of the PET sheet  6  held by the fixed unit  20 . Thus, the one edge  6   a  and the other edge  6   b  of the PET sheet  6  can be joined together over the entire length of the PET sheet. 
     Since the driven gear  37  holds the covered wire  3  at the center of the driven gear  37  and holds the drain wire  4  at the peripheral region of the driven gear  37  and the covered wires  3  are turned for at least one round of rotation, at least a portion of the drain wire  4  can be placed at a periphery relative to the cross section of the wire bundle so as to ensure that the drain wire  4  is brought into contact with the ALS sheet  5  wound around the wire bundle. Accordingly, the electrical noise can be effectively led via the drain wire  4  to the ground circuit. 
     Although, in the first embodiment, the shield harness  2  includes the plurality of covered wires  3  and only one drain wire  4 , the shield harness  2  contemplated in the present invention can have only one covered wire  3  and one drain wire  4 . 
     In addition, although the two edges of the PET sheet  6  are joined together by welding. Joining together of the two edges of the PET sheet  6  can be achieved by adhesive bonding using a suitable adhesive. 
     Second Embodiment 
     The shield harness manufacturing device and method according to the second embodiment of the present invention is described with reference to  FIGS. 22 to 37 . 
     As has been discussed in detail, in the first embodiment, when the ALS sheet  5  is wound around the wire bundle including the plurality of covered wires  3  and the one drain wire  4 , then the ALS-wound wire bundle is wrapped in the PET sheet  6  over the entire length of the ALS-wound wire bundle. Also, the one edge  6   a  and the other edge  6   b  widthwise of the PET sheet  6  are brought into contact with each other over the entire length, and the one edge  6   a  and the other edge  6   b  of the PET sheet  6  are joined together by welding over its entire length. 
     In the second embodiment, in contrast, the covered wires  3  and the drain wire  4  is wrapped in two ALS sheets  105  opposed to each other. In addition, two PET sheets  106  opposed to each other sandwich therebetween the covered wires  3 , the drain wire  4 , and the ALS sheets  105 . The one end  106   a  widthwise of the one PET sheet  105  is welded with the one end  106   a  of the other PET sheet  106  over the entire lengths of the PET sheets  106 . Likewise, the other edge  106   b  width wise of the other PET sheet  106  is welded with the other edge  106   b  of the other PET sheet  106  over the entire length of the PET sheets  106 . It should be noted that the constituent parts and components that have already appeared in the description of the first embodiment are indicated by the same reference numerals as in the first embodiment and the second embodiment will not reiterate their constructions and arrangements that have already been exhaustively discussed in the previous embodiment. 
     A manufacturing device  101  shown in  FIG. 22  is an apparatus that manufactures a shield harness  102  shown in  FIGS. 35 and 36 . The shield harness  102 , as shown in  FIGS. 35 and 36 , has the plurality of covered wires  3  and the one drain wire  4 , and the two electrically conductive ALS sheets  105  and two electrically insulating PET sheets  106 . 
     The ALS sheets  105  each have the thin conductive layer  10  and the insulating layer  11  laminated onto the conductive layer  10 . The two ALS sheets  105  are formed in a shape of a strip. The bundle of the covered wires  3  and the drain wire  4  are wrapped in the ALS sheets  105  with the conductive layer  10  coming radially inward of the wire bundle. As shown in  FIG. 36 , the conductive layer  10  of the ALS sheet  105  remains in contact with the drain wire  4  at least at one peripheral region of the shield harness  102 . 
     The PET sheet  106  is made of flexible and electrically insulating synthetic resin such as polyethylene terephthalate, and formed in a shape of a relatively thin sheet. The two PET sheets  106  are both formed in a shape of a strip. 
     The shield harness  102  is manufactured by (a) binding the plurality of covered wires  3  and the drain wire  4  into a wire bundle, (b) wrapping the wire bundle constituted by the covered wires  3  and the drain wire  4  in the ALS sheets  105  with its conductive layer  10  coming radially inward of the wire bundle, and then (c) wrapping the ALS-wrapped wire bundle in the PET sheet  106  over the entire length of the ALS-wrapped wire bundle. In the finished shield harness  102 , lengths of the ALS sheets  105  and the PET sheets  106  are parallel to the length of the wire bundle. 
     The two ALS sheets  105  are arranged so as to be opposed to each other, and wound around the wire bundle. The two PET sheets  106  (i.e., the first PET sheet and the second PET sheet) sandwich therebetween the ALS-wrapped wire bundle. The one edge  106   a  of the one PET sheet  106  and the one edge  106   a  of the other PET sheet  106  are welded together over the entire lengths of the PET sheets  106 . Likewise, the other edge  106   b  of the one PET sheet  106  and the other edge  106   b  of the other PET sheet  106  are welded together over the entire lengths. 
     Note that, in the same manner as in the first embodiment, the term “wire bundle” only denotes a set or a totality of the electrical wires including the covered wire  3  and the drain wire  4 , and the term “bundle” does in no way necessitate use of a tape or other bundling means that is provided around a portion of the set of the wires. 
     Referring to  FIG. 22 , the manufacturing device  101  has the body  13  and two ALS feeders  114 , two PET feeders  115 , the electrical-wire-holding unit  16 , a guide unit  117 , a conductor-winding unit  118 , an insulator-winding unit  119 , a fixed unit  120 , the movable unit  21 , and the control unit  22 . 
     The ALS feeders  114  and the PET feeders  115  are provided on and rotatably supported by the flat upper surface of the body  13  of the manufacturing device  101 . One of the two ALS feeders  114  has a reel  123   a  and the other ALS feeder a reel  123   b , around which the ALS sheet  105  in a shape of an elongated strip is wound. One of the two PET feeders  115  has a reel  124   a  and the other PET feeder  115  a reel  124   b , around which the PET sheet  106  in a shape of an elongated strip is wound. 
     The reels  123   a  and  123   b  around which the ALS sheets  105  are wound are arranged such that the plurality of covered wires  3  and the drain wire  4  are sandwiched between the two ALS sheets  105 .

     Referring to  FIG. 34 , the fixed unit  120  has a horn  172  and an anvil  173  that are moved close to and away from each other, a piezoelectric vibrator (not shown) that places the horn  172  under ultrasonic vibration, and a cylinder unit (not shown) that moves the horn  172  and the anvil  173  close to and away from each other. 
     The horn  172  and the anvil  173  are spaced from each other in the width direction of the body  13  of the manufacturing device  101 . The horn  172  and the anvil  173  are formed in a shape of a strip whose length is parallel to the width of the body  13 . The piezoelectric vibrator makes the horn  172  vibrate with small amplitude at a frequency of for example 20 KHz. 
     The pair of fixed units  120  (its cylinder unit, to be more specific) moves the horn  172  and the anvil  173  close to each other so that The two PET sheets  106    width direction   one edge  106   a  of the one PET sheet  106  overlaps with the one edge  106   a  of the other PET sheet  106  and likewise the other edge  106   b  of the one PET sheet  106  is overlapped with the other edge  106   b  of the other PET sheet  106 , and the one edges  106   a  are clamped between the horn  172  and the anvil  173  of the one fixed unit  120  and the other edges  106   b  are clamped between the horn  172  and the anvil  173  of the other fixed unit  120 . After that, when the piezoelectric vibrator places the horn  172  under ultrasonic vibration, frictional heat occurs at the one edges  106   a  and the other edges  106   b  of the PET sheets  106  and by virtue of the frictional heat, the one edges  106   a  of the two PET sheets  106  are welded together and likewise the other edges  106   b  of the two Pet sheets  106  are welded together. Welded portions W, which have been achieved by welding the mating edges of the PET sheets, are provided uninterruptedly over the entire length of the covered wires  3 , the drain wire  4 , the ALS sheets  105 , and the PET sheets  106 . 
     Having fully described the construction and arrangement of the manufacturing device  101  according to the second embodiment, the following describes how the shield harness  102  is manufactured by the manufacturing device  101  by applying first the two ALS sheet  105  and then the two PET sheets  106  around the covered wires  3  and the drain wire  4  that are cut in the predetermined length with the terminal fittings  12  attached to the both ends thereof. 
     As preparatory operation, the terminal fitting  12  has to be attached to one end of the covered wires  3  and the drain wire  4 . Then the covered wires  3  and the drain wire  4  are hooked onto the terminal holder  28  of the movable holding unit  25  of the electrical-wire-holding unit  16 , and then the one end of the covered wires  3  and the drain wire  4  is held by the terminal holder  28 . Meanwhile, the other end of the covered wire  3  is inserted into the electrical-wire-holding slit  38  of the driven gear  37  of the rotatable holding unit  26  such that the other end of the covered wires  3  are held. Likewise, the other end of the drain wire  4  is inserted into the drain-wire-holding slit  39  of the driven gear  37  of the rotatable holding unit  26  so that the other end is held. Further, the central portion of the covered wires  3  and the drain wire  4  is received in the electrical-wire-guiding groove  158  of the multiple-component-type guide  142  of the guide unit  117 , and the opening of the electrical-wire-guiding groove  158  is closed by the cover  155 . 
     Further, the tip of the ALS sheet  105  wound around the reel  123   a  of the ALS feeder  114  is passed through the guide hole  147   a  of the ALS-guide  144  of the fixed guide  140  of the guide unit  117  and then between the fixed pulley  152   a  and the movable pulley  153   a  of the sheet feeder  141 , and further into the ALS-guide hole  156   a  formed on the upper guide portion  155  of the multiple-component-type guide  142  so as to be in contact with the sliding blade  143 . 
     Likewise, the tip of the ALS sheet  105  wound around the reel  123   b  of the ALS feeder  114  is passed through the guide hole  147   b  of the ALS-guide  144  of the fixed guide  140  of the guide unit  117  and then between the fixed pulley  152   b  and the movable pulley  153   b  of the sheet feeder  141 , and further into the ALS-guide hole  156   b  formed on the lower guide portion  154  of the multiple-component-type guide  142  so as to be in contact with the sliding blade  143 . 
     Also, the tip of the PET sheet  6  wound around the reel  124   a  of the PET feeder  115  is passed (in order of appearance below) through the guide hole  148   a  of the first PET-guide  145  of the fixed guide  40  of the guide unit  117 , between the guide rollers  50  of the second PET-guide  146 , and between the fixed pulley  152   a  provided at a lower portion of the sheet feeder  141  and the movable pulley  153   a  of the sheet feeder  141 . The tip of the PET sheet  6  is inserted into the PET-guide hole  157   a  provided on the upper guide portion  155  of the multiple-component-type guide  142  so as to be in contact with the sliding blade  143 . 
     Likewise, the tip of the PET sheet  6  wound around the reel  124   b  of the PET feeder  115  is passed (in order of appearance below) through the guide hole  148   b  of the first PET-guide  145  of the fixed guide  140  of the guide unit  117 , between the guide rollers  50  of the second PET-guide  146 , and between the fixed pulley  152   b  provided at a lower portion of the sheet feeder  141  and the movable pulley  153   b  of the sheet feeder  141 . The tip of the PET sheet  6  is inserted into the PET-guide hole  157   b  provided on the lower guide portion  154  of the multiple-component-type guide  142  so as to be in contact with the sliding blade  143 . 
     Upon completion of the preparatory operation, the manufacturing device  101  is now ready to start manufacturing operation. 
     First, the movable pulleys  153   a  and  153   b  are moved close to the fixed pulley  152   b  of the sheet feeder  141  of the guide unit  117 . Then the two ALS sheets  105  are sandwiched between the pulleys  152   b ,  153   a  and pulleys  152   b ,  153   b , respectively. 
     The sliding blade  143  is placed at a position where the guide holes of the sliding blade  143  register with and communicate with the guide holes  156   a ,  156   b ,  157   a , and  157   b  of the multiple-component-type guide  142  (shown in  FIG. 27B ). 
     The main mold  66  and the pair of clamping molds  167   a ,  167   b  of the insulator-winding unit  119  are placed all together at a position where they are not closely aligned with the conductor-winding unit  118  in the longitudinal direction of the body  13  of the manufacturing device  101 . As shown in  FIG. 31A , the upper mold  166   a  of the main mold  166  of the insulator-winding unit  119  and the clamping mold  167   a  mounted on the upper mold  166   a  are raised integrally, and the lower mold  166   b  and the clamping mold  167   b  mounted on the lower mold  166   b  are lowered integrally. 
     The slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) are placed most proximate to the conductor-winding unit  118 , and the pair of chuck members  33  of the electrical-wire-chuck portion  29  are moved close to each other, so that the covered wires  3  and the drain wire  4  are sandwiched between them. Further, the pair of chuck members  34  of the sheet-chuck portion  30  are spaced from each other. The pair of belt units  74  of the movable unit  21  are also spaced from each other. The horn  172  and the anvil  173  of the one fixed unit  120  are spaced from each other. Likewise, the horn  172  and the anvil  173  of the other fixed unit  120  are spaced from each other. 
     Thereafter, as shown in  FIGS. 29A and 29C , the upper mold  163  and the lower mold  162  of the conductor-winding unit  118  are closely overlapped with each other, so that the covered wires  3  and the drain wire  4  are sandwiched between the lower molds  162  and the upper mold  163 . Also, the covered wires  3  and the drain wire  4  are passed through the conductor-winding mold  159 . 
     After that, the motor (not shown) drives and rotates the movable pulleys  153   a ,  153   b  of the sheet feeder  141 , so that the ALS sheets  105  opposed to each other are fed into the through-hole  164  of the main mold  160  of the conductor-winding mold  159  of the conductor-winding unit  118 . Since the diameter of the through-hole  164  gradually decreases toward the side of movable holding unit  25 , the ALS sheets  105  are guided by the inner surface of the through-hole  164  (see  FIG. 29B ), and gradually applied around the wire bundle (i.e., the covered wires  3  and the drain wire  4 ). 
     When the tip of the ALS sheet  105  is passed thorough the through-hole  164  and placed between the pair of chuck members  34  of the sheet-chuck portion  30 , the movable pulleys  153   a  and  153   b  of the sheet feeder  141  stop rotating. The pair of chuck members  34  of the sheet-chuck portion  30  move close to each other, and thus the tip of the covered wires  3 , the drain wire  4 , and the ALS sheet  5  is sandwiched between the chuck members  34 . 
     Following this, the fastening mold  161   a  of the conductor-winding mold  159  is lowered and the tip of the covered wires  3 , the drain wire, and the ALS sheet  5  is sandwiched against the fastening molds  161   a  and  161   b . After that, the ALS sheet  105  is applied around the wire bundle such that the wire bundle and the ALS sheet  5  is in intimate contact with each other. 
     After that, the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is moved away from the conductor-winding unit  118 . Further, the insulator-winding mold  165  is moved along with the movable unit  21  of the insulator-winding unit  119 , so that the insulator-winding mold  165  is placed at a position where the insulator-winding mold  165  is closely aligned with the conductor-winding mold  159  of the conductor-winding unit  118  in the longitudinal direction of the body  13  of the manufacturing device  101 . In this manner, the insulator-winding unit  119  is placed between the conductor-winding unit  118  and the movable holding unit  25 . Thereafter, the pair of chuck members  34  of the sheet-chuck portion  30  are moved away from each other. The movable pulley  153   a  is moved close to the fixed pulley  152 , so that the two PET sheets  106  are sandwiched between the pulleys  152   a  and  153   a  and between the pulleys  152   c  and  153   b , respectively. 
     Thereafter, as shown in  FIGS. 31A and 31C , the upper mold  166   a  is closely overlapped with the lower mold  166   b . The guide groove  169   a  of the upper mold  166   a  registers with the guide groove  169   b  of the lower mold  166   b . The ALS-wrapped wire bundle is received in the through hole defined by the two guide groove  169   a ,  169   b.    
     After that, the motor (not shown) is rotated and movable pulleys  153   a  and  153   b  of the sheet feeder  141 . Thereafter, one of the two PET sheets  106  opposed to each other is fed toward the through-hole  175   a  of the upper mold  166   a  of the main mold  166  of the insulator-winding mold  165  of the insulator-winding unit  119  shown in  FIG. 31A , and the other of the two PET sheets  106  is fed toward the through-hole  175   b  of the lower mold  166   b  of the main mold  166  of the insulator-winding mold  165  of the insulator-winding unit  119  shown in  FIG. 31A . After that, the through-hole  175   a  of the upper mold  166   a  of the main mold  166  makes the one of the two PET sheets  106  take a U-shaped cross-section. Meanwhile, the through-hole  175   b  of the lower mold  166   b  of the main mold  166  makes the other of the two PET sheets  106  take a U-shaped cross-section. As shown in  FIGS. 32B and 32C , the PET sheets  106  having the U-shaped cross-section are placed at the periphery of the ALS-wrapped wire bundle. 
     Thereafter, the tip of the PET sheets  106  on the wire-rest portion  171   a  is passed through the pair of clamping portions  168   a  and  168   b  and positioned between the pair of chuck members  34  of the sheet-chuck portion  30 . Then the movable pulleys  153   a  and  153   b  of the sheet feeder  141  stop rotating, and the pair of chuck members  34  of the sheet-chuck portion  30  are moved close to each other. The tip of the covered wires  3 , the drain wire  4 , the ALS sheets  105 , and the PET sheets  106  are sandwiched between the chuck members  34 . Following this, the clamping molds  167   a  and  167   b  of the insulator-winding mold  165  are moved close to each other. Thus, one edge  106   a  and the other edges  106   b  of the two PET sheets  106  are pressed by the surfaces A and B of the clamping mold  167   a  and  167   b , respectively. 
     Thereafter, the clamping molds  167   a  and  167   b  of the insulator-winding mold  165  are moved close to each other, and, as shown in  FIG. 33A , the surfaces A and B of the clamping portions  168   a  and  168   b  are, tough not in complete contact, but yet very close to each other with a limited degree of gaps left therebetween. The clamping portions  168   a  and  168   b  are very close to each other, and the ALS-wrapped wire bundle is wrapped in the two PET sheets  106 , which are now brought into close contact with each other. 
     Following this, as shown in  FIG. 34 , the horn  172  and the anvil  173  of one of the two fixed unit  120   s  are moved close to each other so that the one edge  106   a  of the one PET sheet  106  and the one edge of the other PET sheet  106  are clamped between the horn  172  and the anvil  173  of the one fixed unit  120  with the horn  172  under ultrasonic vibration by the ultrasonic oscillator. Likewise, the horn  172  and the anvil  173  of the other fixed unit  120  are moved close to each other so that the other edge  106   b  of the one PET sheet  106  and the other edge of the other PET sheet  106  are clamped between the horn  172  and the anvil  173  of the other fixed unit  120  with the horn  172  under ultrasonic vibration by the ultrasonic oscillator. Then, frictional heat occurs at portions of the one edges  106   a  and the other edges  106   b  of the PET sheets  106  that are clamped between the corresponding horn  172  and anvil  173  and, as a result, the edges  106   a  and  6   b  of the PET sheets  106  are welded together. Thereafter, the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is moved away from the conductor-winding unit  118 . As the movable holding unit  25  is moving, the covered wires  3 , the drain wire  4 , the ALS sheets  105 , and the PET sheets  106  are moved away from the conductor-winding unit  118 , and the portions of the one edges  106   a  and the other edges  106   b  of the PET sheets  106  that are clamped between the horn  172  and the anvil  173  are also moved, and as a result the one edges  106   a  and the other edges  106   b  of the PET sheets  106  are welded in the longitudinal direction in response to movement relative to the conductor-winding unit  118 . This means that, as shown in  FIG. 36 , the one edges  106   a  in the width direction of the two PET sheets  106  are welded together and likewise the other edges  106   b  are welded together, so that the welded portions W are provided uninterruptedly over the entire length of the covered wires  3 , the drain wire  4 , the ALS sheets  105 , and the PET sheets  106 . 
     After that, when the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is placed at a position more distant from the rotatable holding unit  26  than the pair of belt units  74  of the movable unit  21  are, then the slider  32  stops moving. Thereafter, the pair of belt units  74  of the movable unit  21  are moved close to each other, so that the PET sheets  106  covering the ALS-wrapped wire bundle is sandwiched between the belt units  74 . Also, the pair of chuck members  33  of the electrical-wire-chuck portion  29  are moved away from each other, and the pair of chuck members  34  of the sheet-chuck portion  30  are moved away from each other, and the driving pulley of the belt unit  74  of the movable unit  21  is rotated. Further, the covered wires  3 , the drain wire  4 , and the ALS sheets  5 , and the PET sheets  6  are moved integrally away from the feeders  114  and  115 . 
     Thereafter, when the ALS sheets  105  and the PET sheets  106  are moved for a predetermined distance, as shown in  FIG. 27C , the sliding blade  143  slides relative to the multiple-component-type guide  142 , and cuts the ALS sheets  105  and the PET sheets  106 , and, immediately before sliding of the sliding blade  143  and accordingly immediately before cutting of the ALS sheets  105  and the PET sheets  106 , the motor of the rotatable holding unit  26  is driven to cause only one round of rotation of the driven gear  37 . After that, since the other end of the drain wire  4  is held at a periphery of the driven gear  37 , the drain wire  4  is positioned at a peripheral region of the circular cross section of the wire bundle, and comes into direct contact with the conductive layer  10  of the ALS sheets  5 . Thus, the rotatable holding unit  26  of the electrical-wire-holding unit  16  controlled by the control unit  22  causes at least one round of rotation of the driven gear  37 . 
     Following this, the sliding blade  143  slides again, and the sliding blade  143  is placed at a position where the guide holes of the sliding blade  143  register with the ALS-guide holes  156   a ,  156   b , and the PET-guide holes  157   a , of the multiple-component-type guide  142 , and the endless belt of the belt unit  74  of the movable unit  21  runs so that the ALS-wrapped wire bundle and the PET sheets  106  covering the ALS-wrapped wire bundle are moved to a position more distant from the feeders  114  and  115  than the movable holding unit  25  is. 
     The manufacturing of the shield harness  102  is thus completed. 
     The shield harness manufacturing device and the shield harness manufacturing method according to the second embodiment of the present invention have the following advantages. 
     The conductor-winding mold  159  is provided to apply the ALS sheets  105  around the wire bundle constituted by the covered wires  3  and the drain wire  4 , and the insulator-winding mold  165  is provided to apply the PET sheets  106  around the ALS-wrapped wire bundle. Thus, the shield harness  102  is manufactured by wrapping the wire bundle first in the ALS sheets  105  and then in the PET sheets  106  around the bundle of the covered wires  3  and the drain wire  4 . 
     Accordingly, the shield harness  102  can be made more light-weight since the need of covering the external surface of the ALS sheets  105  by an insulating synthetic resin is eliminated. Also, since the PET sheets  106  covers the external surface of the ALS sheets  105 , the ALS sheets  105  wound around the wire bundle can be protected against being exposed to an outside, and thus shielding performance of the shield harness  102  can be improved. 
     Also, the conductor-winding mold  159  wraps the covered wires  3  and the drain wire  4  in the ALS sheet  105 . Since the readily-plastically-deformed ALS sheets  105  are wound around the periphery of the wire bundle, the covered wire  3  and the drain wire  4  can be wrapped in the ALS sheets  105  more adhesively and snugly, in stable contact with the electrical wire. Accordingly, the ALS sheet  105  can be effectively wound around the covered wires  3  and the drain wire  4 . 
     Further, the insulator-winding molds  165  sandwiches the ALS sheets  105  therebetween for covering the ALS-wrapped wire bundle by the PET sheet  106 . Since the not-readily-plastically-deformed PET sheets  106  are placed such that the wire bundle is sandwiched therebetween, the PET sheets  106  can be applied without causing damage to them. Accordingly, the covered wires  3 , the drain wire  4 , and the ALS sheet  105  covering the wires can be effectively wrapped in the PET sheet  106 . 
     In addition, since the ends  106   a  and  106   a  and  106   b , and  106   b  are welded over the entire length of the two PET sheets  106 , adjustment can be readily achieved by shifting the welded portions W of the two PET sheets  106  in the width direction of the PET sheets  106  in response to changes in the number and diameter of the covered wires  3  that are covered by the PET sheet  106 . 
     Also, since the ALS sheets  105  that are wound around the wire bundle by the conductor-winding mold  159  is readily plastically deformed. The ALS sheets  105  can be wound more adhesively and in more stable contact with the covered wire  3  and the drain wire  4 . Accordingly, the ALS sheet  5  can be wound around the wire bundle effectively. 
     Since the covered wires  3 , the drain wire  4 , and the ALS sheets  105  are inserted into the through-holes  164   a ,  164   b  of the main mold  160  of the conductor-winding mold  159 , the diameter of the through-holes  164   a ,  164   b  gradually decreasing, the ALS sheets  105  can be effectively wound around the wire bundle. 
     In addition, since the ALS sheets  105  are sandwiched between the fastening molds  161   a  and  161   b , the wound ALS sheets  5  are clamped between the two molds so that the ALS sheets  105  can be snugly wound around the wire bundle. 
     Since the main mold  166  of the insulator-winding mold  165  holds the PET sheets  106  in such a manner that the cross-section of the PET sheets  106  has an U-shape and the one edge  106   a  of the one PET sheet  106  and the one edge  106   a  of the other PET sheet  106  are clamped between the pair of clamping molds  167   a  and  167   b , and likewise the other edge  106   b  of the other PET sheet  106  and the other edge  106  of the PET sheet  106  are clamped between the pair of clamping molds  167   a  and  167   b , the PET sheets  106  can be effectively wound around the ALS-wrapped wire bundle. 
     Since the corresponding two each of the edges  106   a  and  106   b  of the PET sheets  106  are joined with each other by the fixed unit  120 , the corresponding edges of the PET sheets  106  can be joined together with the PET sheets  106  wound around the covered wires  3 , the drain wire  4 , and the ALS sheets  105 . 
     By virtue of the moving unit  21  that carries the covered wires  3 , the drain wire  4 , the ALS sheets  105 , and the PET sheets  106 , the ALS-wrapped wire bundle covered by the PET sheets  106  can be moved with the edges  106   a  and  106   b  of the PET sheets  106  held by the fixed unit  120 . Thus, the one edge  106   a  and the other edge  106   b  of the PET sheet  6  can be joined together uninterruptedly over the entire length of the PET sheets  106 . Also, the occurrence of a gap in the welded portion can be prevented and accordingly exposure of the ALS sheets  105  to an outside can be effectively prevented. 
     Since the driven gear  37  holds the covered wire  3  at the center of the driven gear  37  and holds the drain wire  4  at the peripheral region of the driven gear  37  and the covered wires  3  are turned for at least one round of rotation, at least a portion of the drain wire  4  can be placed at a periphery relative to the cross section of the wire bundle so as to ensure that the drain wire  4  is brought into contact with the ALS sheets  105  wound around the wire bundle. Accordingly, the electrical noise can be effectively led via the drain wire  4  to the ground circuit. 
     Although, in the aforementioned embodiment, the shield harness  102  has the plurality of covered wires  3  and one drain wire  4 , the shield harness  102  of the present invention can be effectuated with at least one covered wire  3  and at least one drain wire  4 . 
     In addition, the edges of the PET sheets  106  are joined together by welding. However, joining together of the edges of the PET sheets  106  can be achieved by adhesive bonding using a suitable adhesive. 
     Third Embodiment 
     The shield harness manufacturing device according to the third embodiment of the present invention is described with reference to  FIGS. 38 to 41 . In the second embodiment, the covered wires  3  and the drain wire  4  are wrapped in the two ALS sheets  105  opposed to each other, the covered wires  3 , the drain wire  4 , and the ALS sheets  105  are placed between the two PET sheets  106  opposed to each other are wrapped in the two PET sheets  106 , and the one edges  106   a  and  106   a  and the other edges  106   b  and  106   b  of the two PET sheets  106  are welded together over the entire length of the PTE sheets  205 . 
     In contrast, however, the third embodiment involves one ALS sheet  205  that is wound around the wire bundle of the covered wires  3  and the drain wire  4 . Thus, the covered wires  3  and the drain wire  4 , and the ALS sheet  205  are placed between two PET sheets  206  opposed to each other and wrapped in the PET sheets  206 . The one edges  206   a  and  206   a  and the other edges  206   b  and  206   b  in the width direction of the PET sheets  206  are welded together over the entire length of the. PET sheets  206 . It should be noted that the constituent parts and components that have already appeared in the description of the first and second embodiments are indicated by the same reference numerals and the third embodiment will not reiterate their constructions and arrangements that have already been exhaustively discussed in the previous embodiments. 
     The manufacturing device  201  shown in  FIG. 38  is an apparatus that manufactures the shield harness  202  shown in  FIG. 40 . The shield harness  202 , as shown in  FIG. 40 , has a plurality of electrical wires, i.e., at least one covered wire  3  and one drain wire  4 , and an aluminum-laminated sheet (ALS sheet)  205  as an electrically conductive sheet, and a PET sheet  206  as an electrically insulating sheet. 
     The ALS sheet  205  is a relatively thin sheet that includes a thin conductive layer  10  and an insulating layer  11  laminated onto the conductive layer  10 . The ALS sheet  205  is formed in a shape of a strip. The ALS sheet  205  is wound around the bundle of the covered wires  3  and the drain wire  4  such that the conductive layer  10  of the ALS sheet  205  comes radially inward of the cross-section of the wire bundle. As shown in  FIG. 40 , the conductive layer  10  of the ALS sheet  205  is in contact with the drain wire  4  at a peripheral region of the shield harness  202 . 
     The PET sheet  206  is made of flexible and electrically insulating synthetic resin such as polyethylene terephthalate, and formed in a shape of a relatively thin sheet. The two PET sheets  206  are formed in a shape of a strip. 
     The shield harness  202  is manufactured by binding the plurality of covered wires  3  and the drain wire  4  into a bundle (note that use of a binding means such as a tape is not presupposed in the preferred embodiments) and then the wire bundle is wrapped first in the ALS sheet  205  with its conductive layer  10  coming radially inward, and the ALS-wound wire bundle is further wrapped in the PET sheet  206 . Here, the ALS sheet  205  and the PET sheets  206  are arranged lengthwise parallel to the covered wires  3  and the drain wire  4 . The ALS sheet  205  is wound around the wire bundle including the covered wires  3  and the drain wire  4 , and the two PET sheets  206  sandwich the ALS-wound wire bundle so that the covered wires  3 , the drain wire  4 , and the ALS sheet  205  are wrapped in the PET sheets  206 . Further, one edges  206   a  and  206   a  of the PET sheets  206  are welded together and the other edges  206   b  and  206   b  thereof are likewise welded together over the entire length of the PET sheets  206 . 
     Referring to  FIG. 38 , the manufacturing device  201  has the body  13 , the ALS feeder  14 , the PET feeder  115 , the electrical-wire-holding unit  16 , a guide unit  217 , the conductor-winding unit  18 , the insulator-winding unit  119 , the fixed unit  120 , the movable unit  21 , and the control unit  22 . 
     The ALS feeder  14  and the PET feeder  115  are provided on the flat upper surface of the body  13  of the manufacturing device  201 . The feeders  14  and  115  are rotatably supported by the body  13  and have a reel  23  around which the ALS sheet  205  in a shape of an elongated strip is wound and reels  124   a  and  124   b  around which the PET sheets  206  are wound, respectively. 
     The reels  124   a  and  124   b  around which the PET sheets  206  are wound are provided at a position where the covered wires  3 , the drain wire  4 , and the reel  23  around which the ALS sheet  205  is wound are found between the reels  124   a  and  124   b  in the vertical direction. Also, the reel  124   a  and the reel  124   b  are arranged on one straight line perpendicular to the longitudinal direction of the body  13 . The one reel  124   a  is provided higher in the vertical direction than the reel  23  around which the ALS sheet  205  is wound. The other reel  124   b  is provided lower than the reel  23  around which the ALS sheet  205  is wound. 
     Referring to  FIG. 38 , the guide unit  217  includes a fixed guide  240 , the sheet feeder  141 , a multiple-component-type guide  242 , and a sliding blade  243 . The guide unit  217  is provided near the feeders  14  and  115  and between the feeders  14 ,  115  and the movable holding unit  25 . The fixed guide  240  is provided near the feeders  14 ,  115  and includes the ALS-guide  44 , the first PET-guide  145 , and the second PET-guide  146 . 
     The multiple-component-type guide  242  is provided near the sheet feeder  141  and closer to the movable holding unit  25  than the sheet feeder  141  is. The multiple-component-type guide  242 , as shown in  FIG. 39A , has the lower guide portion  154  and an upper guide portion  255 . 
     The upper guide portion  255  is formed in a shape of a quadratic prism. The upper guide portion  255  is provided on an upper end of the lower guide portion  154  rotatably from a position where the opening above the electrical-wire-guiding groove  158  is closed to the position where the opening is left open. 
     The PET-guide hole  257   a  extends through the upper guide portion  255  in the longitudinal direction of the body  13  of the manufacturing device  201 . The PET-guide hole  257   a  has an inverted-V-shaped cross-section. When the upper guide portion  255  is positioned in the position where the opening of the electrical-wire-guiding groove  158  is closed, the PET-guide hole  257   a  and the PET-guide hole  157   b  are arranged such that they come close to each other in the longitudinal direction of the body  13 . The PET sheet  206  is passed through the PET-guide hole  257   a.    
     The sliding blade  243  is formed in a shape of a strip and in contact with the lateral surface of the lower guide portion  154  and the upper guide portion  255  of the multiple-component-type guide  242 , the lateral surface being opposed to the movable holding unit  25 . The sliding blade  243  is slidable in the vertical direction. The sliding blade  243  has guide holes (not shown) operable to register with the ALS-guide hole  156   b  and the PET-guide holes  257   a  and  157   b , and inside of which the ALS sheet  205  and the PET sheet  206  are passed. The sliding blade  243  slides in the vertical direction relative to the lower guide portion  154  and the upper guide portion  255 , and cuts the ALS sheet  205  and the PET sheet  206  on the lower guide portion  154  and the upper guide portion  255 . 
     The following describes how the shield harness  202  is manufactured by the manufacturing device  201  by applying first the ALS sheet  205  and then the two PET sheets  206  around the covered wires  3  and the drain wire  4  that are cut in the predetermined length with the terminal fittings  12  attached to the both ends thereof. 
     As preparatory operation, the terminal fitting  12  is attached to one end of the covered wires  3  and the drain wire  4 . Then the covered wires  3  and the drain wire  4  are hooked onto the terminal holder  28  of the movable holding unit  25  of the electrical-wire-holding unit  16 , and then the one end of the covered wires  3  and the drain wire  4  is held by the terminal holder  28 . Meanwhile, the other end of the covered wire  3  is inserted into the electrical-wire-holding slit  38  of the driven gear  37  of the rotatable holding unit  26  such that the other end of the covered wires  3  are held. Likewise, the other end of the drain wire  4  is inserted into the drain-wire-holding slit  39  of the driven gear  37  of the rotatable holding unit  26  so that the other end is held. Further, the central portion of the covered wires  3  and the drain wire  4  is received in the electrical-wire-guiding groove  158  of the multiple-component-type guide  242  of the guide unit  217 , and the opening of the electrical-wire-guiding groove  158  is closed by the cover  255 . 
     Further, the tip of the ALS sheet  205  wound around the reel  23  of the ALS feeder  14  is passed through the guide hole  47  of the ALS-guide  44  of the fixed guide  240  of the guide unit  217  and then between the fixed pulley  152   b  and the movable pulley  153   b  of the sheet feeder  141 , and further into the ALS-guide hole  156   b  formed on the lower guide portion  154  of the multiple-component-type guide  242  so as to be in contact with the sliding blade  243 . 
     Also, the tip of the PET sheet  206  wound around the reel  124   a  of the PET feeder  115  is passed (in order of appearance below) through the guide hole  148   a  of the first PET-guide  145  of the fixed guide  240  of the guide unit  217 , between the guide rollers  50  of the second PET-guide  146 , and between the fixed pulley  152   a  and the movable pulley  153   a  of the sheet feeder  141 . The tip of the PET sheet  206  is inserted into the PET-guide hole  257   a  provided on the upper guide portion  255  of the multiple-component-type guide  242  so as to be in contact with the sliding blade  243 . 
     Likewise, the tip of the PET sheet  206  wound around the reel  124   b  of the PET feeder  115  is passed (in order of appearance below) through the guide hole  148   b  of the first PET-guide  145  of the fixed guide  240  of the guide unit  217 , between the guide rollers  50  of the second PET-guide  146 , and between the fixed pulley  152   b  and the movable pulley  153   b  of the sheet feeder  141 . The tip of the PET sheet  206  is inserted into the PET-guide hole  157   b  provided on the lower guide portion  154  of the multiple-component-type guide  242  so as to be in contact with the sliding blade  243 . 
     Upon completion of the preparatory operation, the manufacturing device  201  is ready to start manufacturing operation. 
     First, the movable pulley  153   b  is moved close to the fixed pulley  152   b  of the sheet feeder  141  of the guide unit  217 . Then the ALS sheet  205  is sandwiched between the pulleys  152   b  and  153   b.    
     The sliding blade  243  is placed at a position where the guide holes of the sliding blade  243  register with and communicate with the guide holes  156   b ,  257   a , and  157   b  of the multiple-component-type guide  242  (shown in  FIG. 39B ). 
     The main mold  166  of the insulator-winding unit  119  is placed at a position where the main mold  166  is not closely aligned with the conductor-winding unit  18  in the longitudinal direction of the body  13  of the manufacturing device  201 . The upper mold  166   a  of the main mold  166  of the insulator-winding unit  119  and the clamping mold  167   a  mounted on the upper mold  166   a  are raised integrally, and the lower mold  166   b  and the clamping mold  167   b  mounted on the lower mold  166   b  are lowered integrally. 
     The slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is placed most proximate to the conductor-winding unit  18 , and the pair of chuck members  33  of the electrical-wire-chuck portion  29  are moved close to each other, so that the covered wires  3  and the drain wire  4  are sandwiched between them. Further, the pair of chuck members  34  of the sheet-chuck portion  30  are spaced from each other. The pair of belt units  74  of the movable unit  21  are also spaced from each other. The horn  172  and the anvil  173  of the one fixed unit  120  are spaced from each other. Likewise, the horn  172  and the anvil  173  of the other fixed unit  120  are spaced from each other. 
     Thereafter, the upper mold  63  and the lower mold  62  of the conductor-winding unit  18  are closely overlapped with each other, so that the covered wires  3  and the drain wire  4  are sandwiched between the lower molds  62  and the upper mold  63 . Also, the covered wires  3  and the drain wire  4  are passed through the conductor-winding mold  59 . 
     After that, the motor (not shown) drives and rotates the movable pulley  153   b  of the sheet feeder  141 , so that the ALS sheet  205  is fed into the through-hole  64  of the main mold  60  of the conductor-winding mold  59  of the conductor-winding unit  18 . Since the diameter of the through-hole  64  gradually decreases toward the side of movable holding unit  25 , the ALS sheet  205  is guided by the inner surface of the through-hole  64 , and gradually applied around the wire bundle (i.e., the covered wires  3  and the drain wire  4 ). 
     When the tip of the ALS sheet  205  is passed thorough the through-hole  64  and placed between the pair of chuck members  34  of the sheet-chuck portion  30 , the movable pulley  153   b  of the sheet feeder  141  stops rotating. The pair of chuck members  34  of the sheet-chuck portion  30  move close to each other, and thus the tip of the covered wires  3 , the drain wire  4 , and the ALS sheet  205  is sandwiched between the chuck members  34 . 
     Following this, the fastening mold  161   a  of the conductor-winding mold  59  is lowered and the tip of the covered wires  3 , the drain wire, and the ALS sheet  5  is sandwiched against the fastening molds  161   a  and  161   b . After that, the ALS sheet  205  is applied around the wire bundle such that the wire bundle and the ALS sheet  205  is in intimate contact with each other. 
     After that, the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is moved away from the conductor-winding unit  18 . Further, the insulator-winding mold  165  is moved along with the movable unit  21  of the insulator-winding unit  119 , so that the insulator-winding mold  165  is placed at a position where the insulator-winding mold  165  is closely aligned with the conductor-winding mold  59  of the conductor-winding unit  18  in the longitudinal direction of the body  13  of the manufacturing device  201 . In this manner, the insulator-winding unit  119  is placed between the conductor-winding unit  18  and the movable holding unit  25 . Thereafter, the pair of chuck members  34  of the sheet-chuck portion  30  are moved away from each other. The movable pulley  153   b  is moved close to the fixed pulley  152   c , so that the two PET sheets  206  are sandwiched between the pulleys  152   c  and  153   a  and between the pulleys  152   c  and  153   b , respectively. 
     Thereafter, the upper mold  166   a  is closely overlapped with the lower mold  166   b . The guide groove  169   a  of the upper mold  166   a  registers with the guide groove  169   b  of the lower mold  166   b . The ALS-wound wire bundle is received in the through-hole defined by the two guide groove  169   a ,  169   b.    
     After that, the motor (not shown) rotates the movable pulleys  153   a  and  153   b  of the sheet feeder  141 . Thereafter, one of the two PET sheets  206  opposed to each other is fed toward the through-hole  175   a  of the upper mold  166   a  of the main mold  166  of the insulator-winding mold  165  of the insulator-winding unit  119 , and the other of the two PET sheets  206  is fed toward the through-hole  175   b  of the lower mold  166   b  of the main mold  166  of the insulator-winding mold  165  of the insulator-winding unit  119 . After that, the through-hole  175   a  of the upper mold  166   a  of the main mold  166  makes the one of the two PET sheets  206  take a U-shaped cross-section. Meanwhile, the through-hole  175   b  of the lower mold  166   b  of the main mold  166  makes the other of the two PET sheets  206  take a U-shaped cross-section. The PET sheets  206  having the U-shaped cross-section are placed at the periphery of the ALS-wound wire bundle. 
     Thereafter, the tip of the PET sheets  206  on the wire-rest portion  171   a  is passed through the pair of clamping portions  168   a  and  168   b  and positioned between the pair of chuck members  34  of the sheet-chuck portion  30 . Then the movable pulleys  153   a  and  153   b  of the sheet feeder  141  stop rotating, and the pair of chuck members  34  of the sheet-chuck portion  30  are moved close to each other. The tip of the covered wires  3 , the drain wire  4 , the ALS sheet  205 , and the PET sheets  206  are sandwiched between the chuck members  34 . Following this, the clamping molds  167   a  and  167   b  of the insulator-winding mold  165  are moved close to each other. Thus, one edges  206   a  and the other edges  206   b  of the two PET sheets  206  are pressed by the surfaces A and B of the clamping mold  167   a  and  167   b , respectively. 
     Thereafter, the clamping molds  167   a  and  167   b  of the insulator-winding mold  165  are moved close to each other, and the surfaces A and B of the clamping portions  168   a  and  168   b  are, tough not in complete contact, but yet very close to each other with a limited degree of gaps left therebetween. The clamping portions  168   a  and  168   b  are very close to each other, and the ALS-wound wire bundle is wrapped in the two PET sheets  206 , which are now brought into close contact with each other. 
     Following this, the horn  172  and the anvil  173  of one of the two fixed units  120  are moved close to each other so that the one edge  206   a  of the one PET sheet  206  and the one edge of the other PET sheet  206  are clamped between the horn  172  and the anvil  173  of the one fixed unit  120  with the horn  172  under ultrasonic vibration by the ultrasonic oscillator. Likewise, the horn  172  and the anvil  173  of the other fixed unit  120  are moved close to each other so that the other edge  206   b  of the one PET sheet  206  and the other edge of the other PET sheet  206  are clamped between the horn  172  and the anvil  173  of the other fixed unit  120  with the horn  172  under ultrasonic vibration by the ultrasonic oscillator. Then, frictional heat occurs at portions of the one edges  206   a  and the other edges  206   b  of the PET sheets  206  that are clamped between the corresponding horn  172  and anvil  173  and, as a result, the edges  206   a  and  206   b  of the PET sheets  206  are welded together. Thereafter, the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is moved away from the conductor-winding unit  18 . As the movable holding unit  25  is moving, the covered wires  3 , the drain wire  4 , the ALS sheet  205 , and the PET sheets  206  are moved away from the conductor-winding unit  18 , and the portions of the one edges  206   a  and the other edges  206   b  of the PET sheets  206  that are clamped between the horn  172  and the anvil  173  are also moved, and as a result the one edges  206   a  and the other edges  206   b  of the PET sheets  206  are welded in the longitudinal direction in response to movement relative to the conductor-winding unit  18 . This means that, as shown in  FIG. 41 , the one edges  206   a  in the width direction of the two PET sheets  206  are welded together and likewise the other edges  206   b  are welded together, so that the welded portions W are provided at given intervals over the entire length of the covered wires  3 , the drain wire  4 , the ALS sheet  205 , and the PET sheets  206 . 
     After that, when the slider  32  of the movable holding unit  25  (and accordingly the terminal holder  28 , the electrical-wire-chuck portion  29 , and the sheet-chuck portion  30 ) is placed at a position more distant from the rotatable holding unit  26  than the pair of belt units  74  of the movable unit  21  are, then the slider  32  stops moving. Thereafter, the pair of belt units  74  of the movable unit  21  are moved close to each other, so that the PET sheets  206  covering the ALS-wound wire bundle is sandwiched between the belt units  74 . Also, the pair of chuck members  33  of the electrical-wire-chuck portion  29  are moved away from each other, and the pair of chuck members  34  of the sheet-chuck portion  30  are moved away from each other, and the driving pulley of the belt unit  74  of the movable unit  21  is rotated. Further, the covered wires  3 , the drain wire  4 , and the ALS sheet  5 , and the PET sheets  6  are moved integrally away from the feeders  14  and  115 . 
     Thereafter, when the ALS sheet  205  and the PET sheets  206  are moved for a predetermined distance, as shown in  FIG. 27C , the sliding blade  243  slides relative to the multiple-component-type guide  242 , and cuts the ALS sheet  205  and the PET sheets  206 , and, immediately before sliding of the sliding blade  243  and accordingly immediately before cutting of the ALS sheet  205  and the PET sheets  206 , the motor of the rotatable holding unit  26  is driven to cause only one round of rotation of the driven gear  37 . After that, since the other end of the drain wire  4  is held at a periphery of the driven gear  37 , the drain wire  4  is positioned at a peripheral region of the circular cross section of the wire bundle, and comes into direct contact with the conductive layer  10  of the ALS sheet  5 . Thus, the rotatable holding unit  26  of the electrical-wire-holding unit  16  controlled by the control unit  22  causes at least one round of rotation of the driven gear  37 . 
     Following this, the sliding blade  243  slides again, and the sliding blade  243  is placed at a position where the guide holes of the sliding blade  243  register with the ALS-guide hole  156   b  and the PET-guide holes  157   a  and  157   b  of the multiple-component-type guide  242 , and the endless belt of the belt unit  74  of the movable unit  21  runs so that the ALS-wound wire bundle and the PET sheets  206  covering the ALS-wound wire bundle are moved to a position more distant from the feeders  14  and  115  than the movable holding unit  25  is. 
     The manufacturing of the shield harness  202  is thus completed. 
     The shield harness manufacturing device and the shield harness manufacturing method according to the third embodiment of the present invention have the following advantages. 
     The conductor-winding mold  59  is provided to apply the ALS sheet  205  around the wire bundle constituted by the covered wires  3  and the drain wire  4 , and the insulator-winding mold  165  is provided to apply the PET sheets  206  around the ALS-wound wire bundle. Thus, the shield harness  202  is manufactured by wrapping the wire bundle first in the ALS sheet  205  and then in the PET sheets  206  around the bundle of the covered wires  3  and the drain wire  4 . 
     Accordingly, the shield harness  202  can be made more light-weight since the need of covering the external surface of the ALS sheet  205  by an insulating synthetic resin is eliminated. Also, since the PET sheets  206  covers the external surface of the ALS sheet  205 , the ALS sheet  205  wound around the wire bundle can be protected against being exposed to an outside, and thus shielding performance of the shield harness  202  can be improved. 
     Also, the conductor-winding mold  59  winds the ALS sheet  205  around the covered wires  3  and the drain wire  4 . Since the readily-plastically-deformed ALS sheet  205  are wound around the periphery of the wire bundle, the covered wire  3  and the drain wire  4  can be wrapped in the ALS sheet  205  more adhesively and snugly, in stable contact with the electrical wire. Accordingly, the ALS sheet  205  can be effectively wound around the covered wires  3  and the drain wire  4 . 
     Further, the insulator-winding molds  165  sandwiches the ALS sheet  205  therebetween for covering the ALS-wound wire bundle by the PET sheets  206 . Since the not-readily-plastically-deformed PET sheets  206  are placed such that the wire bundle is sandwiched therebetween, the PET sheets  206  can be applied without causing damage to the PET sheets  206 . Accordingly, the covered wires  3 , the drain wire  4 , and the ALS sheet  205  covering the wires can be effectively wrapped in the PET sheets  206 . 
     In addition, since the ends  206   a  and  206   a , and ends  206   b  and  206   b  are welded together over the entire length of the two PET sheets  206 , adjustment can be readily achieved by shifting the welded portions W of the two PET sheets  206  in the width direction of the PET sheets  206  in response to changes in the number and diameter of the covered wires  3  that are covered by the PET sheets  206 . 
     Also, since the ALS sheet  205  that are wound around the wire bundle by the conductor-winding mold  59  is readily plastically deformed. The ALS sheet  205  can be wound more adhesively and snugly, in more stable contact with the covered wire  3  and the drain wire  4 . Accordingly, the ALS sheet  205  can be wound around the wire bundle effectively. 
     Since the covered wires  3 , the drain wire  4 , and the ALS sheet  205  are inserted into the through-holes  64  of the main mold  60  of the conductor-winding mold  59 , the diameter of the through-holes  64  gradually decreasing, the ALS sheet  205  can be effectively wound around the wire bundle. 
     In addition, since the ALS sheet  205  are sandwiched between the fastening molds  61 , the wound ALS sheet  5  is clamped between the two molds so that the ALS sheet  205  can be snugly wound around the wire bundle. 
     Since the main mold  166  of the insulator-winding mold  165  holds the PET sheets  206  in such a manner that the cross-section of the PET sheets  206  has an U-shape and the one edge  206   a  of the one PET sheet  206  and the one edge  206   a  of the other PET sheet  206  are clamped between the pair of clamping molds  167   a  and  167   b , and likewise the other edge  206   b  of the other PET sheet  206  and the other edge  206  of the PET sheet  206  are clamped between the pair of clamping molds  167   a  and  167   b , the PET sheets  206  can be effectively wound around the ALS-wound wire bundle. 
     Since the corresponding two each of the edges  206   a  and  206   b  of the PET sheets  206  are joined with each other by the fixed unit  120 , the corresponding edges of the PET sheets  206  can be joined together with the PET sheets  206  wound around the covered wires  3 , the drain wire  4 , and the ALS sheet  205 . 
     By virtue of the moving unit  21  that carries the covered wires  3 , the drain wire  4 , the ALS sheet  205 , and the PET sheets  206 , the ALS-wound wire bundle covered by the PET sheets  206  can be moved with the edges  206   a  and  206   b  of the PET sheets  206  held by the fixed unit  120 . Thus, the one edge  206   a  and the other edge  206   b  of the PET sheet  206  can be joined together over the entire length of the PET sheet  206 . Also, the occurrence of a gap in the welded portion W can be prevented and accordingly exposure of the ALS sheet  205  to an outside can be effectively prevented. In addition, since the welded portions W are provided at the given intervals, processing time required to complete the welding of the PET sheets  205  can be shortened when compared with the welding step where the edges of the PET sheets  206  are welded together uninterruptedly over the entire length of the PET sheets  206 . 
     Since the driven gear  37  holds the covered wire  3  at the center of the driven gear  37  and holds the drain wire  4  at the peripheral region of the driven gear  37  and the covered wires  3  are turned for at least one round of rotation, at least a portion of the drain wire  4  can be placed at a periphery relative to the cross section of the wire bundle so as to ensure that the drain wire  4  is brought into contact with the ALS sheet  205  wound around the wire bundle. Accordingly, the electrical noise can be effectively led via the drain wire  4  to the ground circuit. 
     Although, in the third embodiment, the shield harness  202  has the plurality of covered wires  3  and one drain wire  4 , the shield harness  202  of the present invention can be effectuated with at least one covered wire  3  and at least one drain wire  4 . 
     In addition, the edges of the PET sheets  206  are joined together by welding. However, joining together of the edges of the PET sheets  206  can be achieved by adhesive bonding using a suitable adhesive. 
     Having now fully described the preferred embodiment of the present invention, it is clear that the descriptions and explanation contained herein are only cited by way of example rather than limitation, and therefore the present invention can be effectuated with modifications, changes, variations, substitutions, and equivalents without departing from the scope and sprit of the present invention as defined by the appended claims.
