Title: Threadlike adhesive sticking apparatus and method of sticking threadlike adhesive

Description:
TECHNICAL FIELD 
     The present invention relates to a threadlike adhesive sticking apparatus and a method of sticking a threadlike adhesive. 
     BACKGROUND ART 
     An adhesive body such as an adhesive sheet and an adhesive tape is used for bonding various adherends such as metal, glass, wood, paper, cardboard, and plastic material. For example, in a case of a wound form such as a roll-shaped adhesive tape, a base material of which a rear surface to be brought into contact with an adhesive surface is subjected to a releasing treatment is used in order to facilitate rewinding. 
     As an adhesive tape sticking apparatus, there is an apparatus in which a holder is moved while pressing an adhesive tape pulled out from a tip end of the holder for storing a roll-shaped adhesive tape against an adherend with a roller provided at the tip end of the holder, thereby sticking the adhesive tape to the adherend while pulling out the adhesive tape (see Patent Literatures 1 and 2). In addition, there is also an adhesive tape sticking apparatus by which an adhesive tape pulled out from a hole at a tip end of a holder for storing an adhesive tape is stuck to an adherend by being brought into contact with the adherend with a peripheral wall surrounding the hole (see Patent Literature 3).

     SUMMARY OF INVENTION 
     Technical Problem 
     However, in the sticking apparatuses described in Patent Literatures 1 and 2, since the adhesive tape is pressed and stuck by the roller, the adhesive tape may be detached from the roller or may be shaken within a width of the roller. Therefore, the sticking accuracy is not good, and it is difficult to make small turns. In addition, when the adhesive tape is stuck in a curved line shape, the adhesive tape is twisted, and thus the adhesive tape cannot be appropriately stuck. 
     In the sticking apparatus described in Patent Literature 3, an orientation of the adhesive tape is aligned by a roller provided in a lead-out portion before the adhesive tape is fed out from the lead-out portion. That is, since a tip end portion contributing to sticking is only one side of the peripheral wall surrounding the rectangular hole, which presses a side that does not have an adhesive layer in the base material of the adhesive tape, only a straight line can be drawn. In addition, the adhesive tape may be shaken within the width of the rectangular hole. 
     The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a threadlike adhesive sticking apparatus and a method of sticking a threadlike adhesive, by which a threadlike adhesive can be accurately stuck to any path. 
     Solution to Problem 
     A threadlike adhesive sticking apparatus of the present invention includes a nozzle having an inner wall surface defining a cylindrical internal space and a tip end having a tip end opening at one end of the inner wall surface, the tip end opening allowing the internal space to communicate with the outside. A plurality of portions of a peripheral portion surrounding the tip end opening at the tip end function as a pressing unit that presses a threadlike adhesive, which has been allowed to pass through the internal space and has been led out to the outside from the tip end opening, against an object. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, the tip end opening has a circular cross-sectional shape or a polygonal cross-sectional shape having five or more corners. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, the pressing unit comes into contact with an adhesive surface of the threadlike adhesive to press the threadlike adhesive against the object. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, the pressing unit presses the threadlike adhesive against the object while sliding on the adhesive surface. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, a dynamic friction force between a portion of the pressing unit in contact with the adhesive surface and the adhesive surface is 3 N/mm or less. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, at least a portion of the pressing unit in contact with the adhesive surface is formed of at least one of a fluorine resin, a silicone resin, or a polyolefin resin. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, at least a portion of the pressing unit in contact with the adhesive surface is treated by at least one of fluorine coating, silicone coating, or long-chain alkyl coating. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, a portion of the pressing unit that presses the adhesive surface is a curved surface. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, a roller is not provided in the internal space. 
     In the threadlike adhesive sticking apparatus of the present invention, for example, the threadlike adhesive includes a linear core material and an adhesive layer configured to cover a surface of the core material in a longitudinal direction. 
     The threadlike adhesive sticking apparatus of the present invention is, for example, an apparatus that presses the threadlike adhesive wound around a winding body against the object while feeding out the threadlike adhesive, further includes an assist mechanism configured to apply an external force in a feeding direction to the threadlike adhesive fed out from the winding body, and the pressing unit presses the fed out threadlike adhesive against the object. 
     The threadlike adhesive sticking apparatus of the present invention includes, for example, a nozzle displacement unit attached to the nozzle and configured to displace the nozzle by being displaced in a pressing direction, and an absorption mechanism configured to absorb a displacement of the nozzle with respect to a displacement of the nozzle displacement unit in the pressing direction. 
     A method of sticking a threadlike adhesive of the present invention includes pressing the threadlike adhesive against the object by using the threadlike adhesive sticking apparatus of the present invention. 
     Advantageous Effects of Invention 
     According to the present invention, it is possible to accurately stick the threadlike adhesive to any path.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, threadlike adhesive sticking apparatuses according to preferred embodiments of the present invention will be described in detail with reference to the drawings. 
     First Embodiment 
       FIG.  1    is a view conceptually showing a configuration of a threadlike adhesive sticking apparatus according to a first embodiment of the present invention.  FIGS.  2  to  5    are views showing specific examples of a conveyance path of a threadlike adhesive in the threadlike adhesive sticking apparatus according to the first embodiment.  FIG.  2    and  FIG.  4    are views showing the threadlike adhesive sticking apparatus as viewed from a rear side.  FIG.  3    and  FIG.  5    are views showing the threadlike adhesive sticking apparatus as viewed from a left side. Arrows shown in  FIG.  2    to  FIG.  8    indicate front-rear, left-right, and up-down directions of the threadlike adhesive sticking apparatus. The front-rear direction is also referred to as an X-axis direction, the left-right direction (width direction) is also referred to as a Y-axis direction, and the up-down direction (height direction) is also referred to as a Z-axis direction. 
     A threadlike adhesive sticking apparatus  101  is an apparatus that presses and sticks a threadlike adhesive  2  to an object (adherend). The threadlike adhesive sticking apparatus  101  mainly includes a supply unit AU, a pressing mechanism BU (nozzle), a conveyance unit CU, and a positioning unit DU as shown in  FIG.  1   . The supply unit AU supplies the threadlike adhesive  2  wound in a roll shape. The pressing mechanism BU presses the supplied threadlike adhesive  2  against the adherend. The conveyance unit CU conveys the threadlike adhesive  2  from the supply unit AU to the pressing mechanism BU. The positioning unit DU positions the pressing mechanism BU relative to the object. 
     Positioning Unit DU 
     The threadlike adhesive sticking apparatus  101  includes a table disposed on a base and a stage that is slidable on the table along the X-axis direction (front-rear direction), as a part constituting an example of the positioning unit DU. The object is placed on an upper surface of the stage and mounted by suction or the like. When the stage is moved in the X-axis direction by a driving unit, the object is moved in the X-axis direction. In addition, the threadlike adhesive sticking apparatus  101  includes, for example, a pair of support columns erected on left and right sides of the table, and a horizontal arm installed between the pair of support columns along the Y-axis direction (left-right direction) above the pair of support columns. 
     A horizontal moving unit  105  (see  FIG.  5   ) that is slidable along the Y-axis direction is attached to the horizontal arm. The horizontal moving unit  105  is moved in the Y-axis direction by a driving unit (not shown). The horizontal moving unit  105  has a substantially rectangular parallelepiped shape, and a lifting body (not shown) provided below is slidably held in the Z-axis direction (up-down direction). A nozzle  107  is attached to the lifting body via an attachment plate  106 . That is, in the horizontal moving unit  105 , the nozzle  107  is moved in the Z-axis direction by a driving unit (not shown). Details of the nozzle  107  will be described later. 
     In the threadlike adhesive sticking apparatus  101 , the nozzle  107  can be positioned relative to the object in an XY plane by the stage and the horizontal moving unit  105 , and the nozzle  107  can be moved in the Z-axis direction by raising and lowering the lifting body of the horizontal moving unit  105 . That is, the stage and the horizontal moving unit  105  function as the positioning unit DU. 
      Supply Unit AU 
     The threadlike adhesive sticking apparatus  101  includes a winding body and a winding body holding unit as an example of the supply unit AU. The winding body has a cylindrical shape such as a reel, a paper tube, and a bobbin. The threadlike adhesive  2  obtained by attaching an adhesive to a threadlike core material is wound around an outer peripheral surface of the winding body. The winding body can be formed of a metal, a resin, an easily releasable material, or the like. The winding body holding unit holds the winding body such that movement of the winding body in the front-rear direction is restricted in the vicinity of both ends of the winding body around which the threadlike adhesive  2  is wound, and the winding body is rotatable as the threadlike adhesive  2  is conveyed (fed out). 
     The threadlike adhesive  2  is an adhesive body obtained by covering a surface of a threadlike core material with an adhesive layer. Details of the threadlike adhesive  2  will be described later. 
     The threadlike adhesive sticking apparatus  101  can supply the threadlike adhesive  2  wound in a roll shape by the winding body and the winding body holding unit. That is, the winding body and the winding body holding unit function as the supply unit AU. 
     Conveyance Unit CU 
     The threadlike adhesive sticking apparatus  101  includes a roller  122  and each pair of rollers  123 ,  124 ,  125 , and  128  as an example of the conveyance unit CU, and conveys the threadlike adhesive  2  fed out from the supply unit AU (winding body) to the nozzle  107 . In the roller  122  and each pair of rollers  123 ,  124 ,  125 , and  128 , at least the outer peripheral surface (rotating surface) in contact with the threadlike adhesive  2  is a non-adhesive surface. That is, at least the outer peripheral surface of each roller in contact with the threadlike adhesive  2  is formed of, for example, at least one of a fluorine resin, a silicone resin, and a polyolefin resin. Alternatively, at least the outer peripheral surface of each roller in contact with the threadlike adhesive  2  is subjected to a non-adhesive treatment by, for example, at least one of fluorine coating, silicone coating, long-chain alkyl coating, and Tosical (registered trademark) coating. The treatment by fluorine coating includes a treatment by a fluorine resin heat-shrinkable tube and a fluorine resin fabric sheet. Alternatively, at least the outer peripheral surface of each roller in contact with the threadlike adhesive  2  may be subjected to various non-adhesive treatments on the base material. For example, the base material may be uneven by blasting, and concave portions may be coated with a non-adhesive substance, or the base material may be treated with PEEK (polyether ether ketone) coating, fluorine composite electroless nickel plating (in which fine particles of a fluorine resin are dispersed and co-deposited in a film of electroless nickel plating), Biceram (fluorine resin coating containing micronized ceramic particles), fiber reinforced plastics (FRP) lining, ultrahigh molecular polyester (PE) lining, or the like. 
     The roller  122  and each pair of rollers  123  and  124  are attached to a rear side of a frame  111 . The frame  111  is installed, along the Y-axis direction, between a pair of frames erected on a left side of the winding body holding unit  121  and a right side of the table, on the base. 
     The roller  122  is rotatably attached to a rectangular attachment portion  111   a  extending downward in the vicinity of a left end portion of the frame  111 , in a perpendicular plane (YZ plane). As shown in  FIG.  3   , the roller  122  preferably has a bobbin shape having flanges at both ends. When the threadlike adhesive  2  is fed out from the winding body, the threadlike adhesive  2  is moved in a width direction of the body of the roller  122 , and the threadlike adhesive  2  is less likely to fall off from the roller  122  due to the flanges at both ends. The pair of rollers  123  is rotatably attached to a rectangular attachment portion  111   b  extending in the front-rear direction on a right side of the attachment portion  111   a  on the frame  111 , in a horizontal plane (XY plane). On the attachment portion  111   b , the pair of rollers  123  is disposed adjacent to the front and rear so as to be separated from each other so that the threadlike adhesive  2  can be allowed to pass therebetween while being guided by the rotating surfaces of the pair of rollers  123  (see  FIG.  3   ). The threadlike adhesive  2 , which has been fed upward from the winding body and has been allowed to pass through the rotating surfaces (outer peripheral surfaces) of the roller  122  on the left side and the upper side as shown in  FIG.  2   , is allowed to pass between the pair of rollers  123  and reaches the pair of rollers  124  as shown in  FIG.  3   . 
     The pair of rollers  124  is rotatably attached in the perpendicular plane on the right side of the pair of rollers  123  on the frame  111 . The pair of rollers  124  are disposed adjacent to the left and right so as to be separated from each other so that the threadlike adhesive  2  can be allowed to pass therebetween while being guided by the rotating surfaces of the pair of rollers  124  (see  FIG.  2    and  FIG.  3   ). As shown in  FIG.  3   , the threadlike adhesive  2 , which has been allowed to pass between the pair of rollers  123 , is allowed to pass through the upper rotating surface of the right roller  124  from the lower rotating surface of the left roller  124 , and reaches the pair of rollers  125 . The pair of rollers  123  and the pair of rollers  124  can prevent meandering of the threadlike adhesive  2  fed out from the winding body, but these are not necessarily required, and the rollers  123  and  124  may not be provided. 
     The pair of rollers  125  is rotatably attached to a lower side of an oil damper  126  extending substantially in the Z-axis direction, in the perpendicular plane. An upper end portion of the oil damper  126  is rotatably fixed to a damper attachment portion having a substantially rectangular shape, in the perpendicular plane. The damper attachment portion protrudes downward substantially at the center of the frame  111  in the Y-axis direction. The pair of rollers  125  is disposed adjacent to each other along an extending direction of the oil damper so as to be separated from each other so that the threadlike adhesive  2  can be allowed to pass therebetween while being guided by the rotating surfaces of the pair of rollers  125  (see  FIG.  4   ). As shown in  FIG.  5   , the threadlike adhesive  2 , which has been allowed to pass between the pair of rollers  124 , is allowed to pass through the right and lower rotating surfaces of the upper roller  125 , is allowed to pass through the upper and left rotating surfaces of the lower roller  125 , and reaches a pair of rollers  128 . The threadlike adhesive  2  guided by the pair of rollers  125  is prevented from sagging by a lower part of the oil damper  126  swinging slowly to the left and right. 
     The pair of rollers  125  and the oil damper  126  may not be provided. This is because, by changing a location where the winding body is placed or a moving speed of the positioning unit DU, the sagging of the threadlike adhesive  2  does not occur, and the function of preventing the sagging by the pair of rollers  125  and the oil damper  126  becomes unnecessary. 
     The pair of rollers  128  is rotatably attached to a roller attachment portion  106   a  of the attachment plate  106  disposed on a front of the horizontal moving unit  105 , in the perpendicular plane. The pair of rollers  128  is disposed adjacent to the left and right so as to be separated from each other so that the threadlike adhesive  2  can be allowed to pass therebetween while being guided by the rotating surfaces of the pair of rollers  128 . As shown in  FIG.  6   , the threadlike adhesive  2  which has been allowed to pass between the pair of rollers  125 , is allowed to pass between the pair of rollers  128  and reaches the nozzle  107 . Since the pair of rollers  128  is provided directly above the nozzle  107  attached to the attachment plate  106 , the threadlike adhesive  2  is guided by the pair of rollers  128  and enters straight into a cylindrical internal space  107   s  (see  FIG.  7   ) of the nozzle  107  regardless of the position of the nozzle  107 . The pair of rollers  128  may be disposed adjacent up and down and guide the threadlike adhesive  2  to the position of the nozzle  107  by passing the threadlike adhesive  2  in an S-shape, or may guide the threadlike adhesive  2  to the position of the nozzle  107  by another configuration. 
     The threadlike adhesive sticking apparatus  101  conveys the threadlike adhesive  2  from the supply unit AU to the pressing mechanism BU by the roller  122  and each pair of rollers  123 ,  124 ,  125 , and  128 . 
     That is, the roller  122  and each pair of rollers  123 ,  124 ,  125 , and  128  function as the conveyance unit CU. The conveyance unit CU may convey the threadlike adhesive  2  to a unit other than the pressing mechanism BU, for example, a pressing unit that presses the threadlike adhesive  2  against the adherend with a roller. 
     Pressing Mechanism BU 
     An example of the pressing mechanism BU provided on the threadlike adhesive sticking apparatus  101  will be described with reference to  FIGS.  6  to  8   .  FIGS.  6  to  8    are views showing the periphery of the nozzle  107  of the threadlike adhesive sticking apparatus  101 .  FIG.  6    is a perspective view showing the periphery of the nozzle  107  as viewed from a front upper side.  FIG.  7    is a view including a cross-section of the nozzle  107  in the YZ plane along the threadlike adhesive  2 .  FIG.  8    is a view showing a state of cutting the threadlike adhesive  2 . 
     The threadlike adhesive sticking apparatus  101  includes the attachment plate  106  and the nozzle  107  as a part constituting an example of the pressing mechanism BU. The attachment plate  106  is slidably attached in the Z-axis direction with respect to the horizontal moving unit  105  on the front side of the horizontal moving unit  105 . The attachment plate  106  is a thin metal flat plate formed in a substantially U shape, and includes the roller attachment portion  106   a , a nozzle attachment portion  106   b  (nozzle displacement unit), and a substantially rectangular connection portion elongated in the Z direction. The roller attachment portion  106   a  is a substantially rectangular portion extending in the Y-axis direction above the connection portion. The pair of rollers  128  are attached to the front side of the roller attachment portion  106   a . The nozzle attachment portion  106   b  is a substantially rectangular portion extending in the Y direction below the connection portion. The nozzle  107 , an air chuck  108 , and an air scissor  109  are attached to the front side of the nozzle attachment portion  106   b . 
     The nozzle  107  is a member formed of aluminum or the like and having a shape obtained by connecting a bottom surface of a cone to a lower surface of a cube. The nozzle  107  has an inner wall surface  107   b  that defines the cylindrical internal space  107   s  extending in the up-down direction, and a tip end  107   d  having a tip end opening  107   c  at a lower end portion of the inner wall surface  107   b , the tip end opening  107   c  allowing the cylindrical internal space  107   s  to communicate with the outside. The nozzle  107  is a member formed of metal or the like, and the surface of the nozzle  107  including the inner wall surface  107   b  and the tip end  107   d  is subjected to a slidability improving process. The nozzle  107  has an insertion-side opening  107   e  at the upper end portion of the inner wall surface  107   b , the insertion-side opening  107   e  allowing the cylindrical internal space  107   s  to communicate with the outside. The inner wall surface  107   b  is formed such that the cylindrical internal space  107   s  has a funnel shape in which a cylinder having the same diameter as the tip end opening  107   c  extends upward from the tip end opening  107   c  and gradually increases in diameter. The insertion-side opening  107   e  has a funnel shape whose diameter is larger than that of the tip end opening  107   c . Note that the inner wall surface  107   b  needs only to define a cylindrical internal space, and for example, an upper portion of the inner wall surface  107   b  may be formed as a cylinder or the like having the same diameter instead of a funnel shape. 
     In the cylindrical internal space  107   s  of the nozzle  107 , a tube  107   a  formed of a hardly adhesive resin such as polytetrafluoroethylene (PTFE) and having a hollow cylindrical shape from the upper end to below the lower end (tip end  107   d ) of the nozzle  107  may be provided. Alternatively, a surface treatment for improving slidability may be performed. A diameter of the threadlike adhesive  2  is preferably, for example, 0.45 mm with respect to a diameter of the lower side opening of, for example, about 1 mm in the tube  107   a . That is, a cross-sectional area of the lower side opening of the tube  107   a  is preferably about 4.9 times a cross-sectional area of the threadlike adhesive  2 . The tube  107   a  protrudes slightly (for example, about 0.5 mm to 1 mm) from the lower end of the inner wall surface  107   b . By inserting the threadlike adhesive  2  into the tube  107   a , the slidability (feedability) of the threadlike adhesive  2  is improved. Since the insertion-side opening  107   e  is enlarged in diameter, it is easy to insert the threadlike adhesive  2  into the nozzle  107 . In addition, when a material of the nozzle  107  itself is a hardly adhesive resin such as PTFE, it is possible to prevent the threadlike adhesive  2  from adhering to the nozzle  107 . As a result, the threadlike adhesive  2  can be smoothly fed out from the nozzle  107  without being caught, and thus the tube  107   a  is unnecessary. Further, a shape of the nozzle  107  is not limited as long as the nozzle  107  has a cylindrical internal space and a tip end having a tip end opening through which the internal space communicates with the outside. In addition, in the nozzle  107 , a shape of the tip end opening  107   c  (or a lower side opening of the tube  107   a ) is preferably a circular shape or a polygonal shape having five or more corners. 
     The nozzle  107  presses the threadlike adhesive  2 , which has been allowed to pass through the tube  107   a  (cylindrical internal space  107   s ) and has been led out to the outside from the lower side opening (tip end opening  107   c ) of the tube  107   a , against the object. More specifically, an entire circumference or a plurality of any positions of the lower end portion of the tube  107   a  which is the peripheral portion surrounding the tip end opening  107   c  of the nozzle  107  function as the pressing unit that presses the threadlike adhesive  2  against the object. Therefore, it is possible to stick the threadlike adhesive while moving the nozzle  107  in a plurality of any directions without using a roller or the like as the pressing unit. Therefore, in a case where the adhesive is pressed by the roller, it is possible to prevent a problem that the adhesion accuracy is poor due to the movement of the adhesive within a roller width, and the adhesive is detached from the roller depending on an adhesion path, and thus it is possible to accurately stick the threadlike adhesive. 
     Relationship Between Hole Diameter of Nozzle  107  and Diameter of Threadlike Adhesive  2   
     A hole diameter of the nozzle  107  (diameter on an inner side (inner diameter), a hole diameter of the tube  107   a  in the case where the tube  107   a  is provided) is preferably 0.7 mm to 1 mm in diameter in the case where the threadlike adhesive  2  has a diameter of 0.45 mm (a width of 0.6 mm in compression of about 0.3 MPa). When the hole diameter of the nozzle  107  is smaller than 0.7 mm, an area of the threadlike adhesive  2  in contact with the inside of the nozzle  107  becomes large, and thus the threadlike adhesive  2  does not stick to the adherend. On the other hand, when the hole diameter of the nozzle  107  exceeds 1 mm and is too large, the threadlike adhesive  2  is moved inside the nozzle  107 , and thus a sticking speed does not increase and the sticking accuracy deteriorates. Therefore, a ratio of the diameter of the threadlike adhesive  2  to the hole diameter of the nozzle  107  is preferably 0.45:0.7 to 1. 
     In addition, the nozzle  107  presses the threadlike adhesive  2  against the object while the lower side opening (or the tip end opening  107   c ) of the tube  107   a  comes into contact with and slides on the adhesive surface of the threadlike adhesive  2 . Specifically, the tip end  107   d  of the nozzle  107  (or the tip end of the tube  107   a , at least a portion in contact with the adhesive surface) may be formed of at least one of a fluorine resin, a silicone resin, or a polyolefin resin. Alternatively, the tip end  107   d  of the nozzle  107  (or the tip end of the tube  107   a , at least a portion in contact with the adhesive surface) is treated by at least one of fluorine coating, silicone coating, or long-chain alkyl coating. Alternatively, various slidability improving processes described below are performed. The treatment by fluorine coating includes a treatment by a fluorine resin heat-shrinkable tube and a fluorine resin fabric sheet. 
     The tip end portion of the nozzle  107  may be subjected to various slidability improving processes on the base material. For example, the base material may be treated with PEEK (polyether ether ketone) coating, fluorine composite electroless nickel plating (in which fine particles of a fluorine resin are dispersed and co-deposited in a film of electroless nickel plating), Biceram (fluorine resin coating containing micronized ceramic particles), fiber reinforced plastics (FRP) lining, ultrahigh molecular polyester (PE) lining, or the like. As a result, the threadlike adhesive  2  can be smoothly stuck to the object. 
     When the nozzle  107  in contact with the adhesive surface of the threadlike adhesive  2  is not hardly adhesive, it is preferable that a dynamic friction force between the tip end  107   d  coated/treated for improving slidability and the adhesive surface is 3 N/mm or less. In a case where the tube  107   a , which is formed of a hardly adhesive resin, is inserted into the nozzle  107 , it is preferable that a dynamic friction force between the lower side opening of the tube  107   a  and the adhesive surface of the threadlike adhesive  2  is 3 N/mm or less. When the nozzle  107  itself is formed of a hardly adhesive resin such as PTFE (silicone, olefin, etc.), a dynamic friction force between the tip end opening  107   c  and the adhesive surface of the threadlike adhesive  2  is preferably 3 N/mm or less. 
     In this way, due to a shape of the tip end portion of the nozzle  107  (details will be described later) and a material/surface treatment, the tip end portion of the nozzle  107  in contact with the adhesive surface of the threadlike adhesive  2  has a low frictional force with respect to the adhesive surface. In addition, since the tip end portion of the nozzle  107  is formed of a material with reduced unevenness or is subjected to a surface treatment, it is possible to inhibit occurrence of scraping or the like when the soft threadlike adhesive  2  slides thereon. Therefore, the threadlike adhesive  2  can be smoothly stuck. The dynamic friction force between the tip end portion of the nozzle  107  and the adhesive surface of the threadlike adhesive  2  can be measured by the following method. 
     As shown in  FIG.  9   , the nozzle  107  is placed on a horizontal plane so that the cylindrical internal space  107   s  extends in the horizontal direction, and the threadlike adhesive  2  inserted from the insertion-side opening  107   e  is pulled out from the tip end opening  107   c . The threadlike adhesive  2  is set so that an angle formed by the threadlike adhesive  2  which has been allowed to pass through the cylindrical internal space  107   s  and the threadlike adhesive  2  pulled out from the tip end opening  107   c  is 60 degrees. By setting in this manner, the threadlike adhesive  2  reliably comes into contact with the tip end portion of the nozzle  107 . On an insertion-side opening  107   e  side, tension is applied to the threadlike adhesive  2  with a weight of 10 g. In this state, the threadlike adhesive  2  pulled out from the tip end opening  107   c  is pulled upward in the vertical direction at 1 mm/sec, and a stress (value at the time of stabilization) is measured. At this time, a width (thickness) of the threadlike adhesive  2  that has pressed against the nozzle tip end indicated by a circle in  FIG.  9    is, for example, 0.4 mm. A value obtained by dividing a value of a stress when the threadlike adhesive  2  is being moved in this way by the width of the threadlike adhesive  2  is defined as the dynamic friction force. 
     Since the tip end portion of the nozzle  107  in the present embodiment has a dynamic friction force of 3 N/mm or less with respect to the adhesive surface of the threadlike adhesive  2 , the threadlike adhesive  2  can be smoothly stuck. In addition, the dynamic friction force between the tip end portion of the nozzle  107  and the adhesive surface of the threadlike adhesive  2  is preferably 1 N/mm or less. The dynamic friction force between the tip end portion of the nozzle and the adhesive surface of the threadlike adhesive  2  is 3 N/mm or less not limited in the case where the width (thickness) of the threadlike adhesive  2  that has pressed against the nozzle tip end is 0.4 mm, and also in the case where the width (thickness) of the threadlike adhesive  2  that has pressed against the nozzle tip end is 0.2 mm to 0.45 mm or other sizes. 
     Furthermore, when the shape of the tip end opening  107   c  (or the lower side opening of the tube  107   a ) is a circular shape or a polygonal shape having five or more corners, the nozzle  107  can easily change a sticking direction. 
       FIG.  10 A  and  FIG.  10 B  are enlarged cross-sectional views of the tip end  107   d  of the nozzle  107 , and shows an example of the nozzle  107  having a shape different from that described above. The nozzle  107  may be formed of a hardly adhesive resin such as fluorine, or may be a nozzle which is formed of a metal and whose surface has been subjected to a slidability improving process. In  FIG.  10 A , since the tip end  107   d  has a corner, the threadlike adhesive  2  may be caught, displaced, or cut. In  FIG.  10 B , since the tip end  107   d  is round, that is, the portion pressing the threadlike adhesive  2  is a curved surface, the threadlike adhesive  2  is not caught and can be favorably stuck. When the nozzle  107  shown in  FIG.  10 B  is formed of a resin such as fluorine, the nozzle  107  may be protected by passing the nozzle  107  through a guide formed of stainless steel (SUS). 
     The nozzle  107  is configured to be movable in the up-down direction and include an absorption mechanism that absorbs a displacement of the nozzle  107  with respect to a displacement of a base to which the nozzle  107  is attached in the up-down direction. Hereinafter, an example of this configuration will be described, but the configuration related to the displacement of the nozzle is not limited to the following configuration. The nozzle  107  is fixed to a slider  132  movable in the up-down direction along a slide rail  133 . The slider  132  has a substantially rectangular parallelepiped shape, with portions of the left and right side surfaces having bulging portions  132   a  respectively protruding to the left and right sides. 
     The slide rail  133  is attached to the front of the nozzle attachment portion  106   b  along the up-down direction. Two bolts  134  and springs  136  and  137  disposed between the two bolts  134  are respectively provided on the left and right sides of the slide rail  133  along the up-down direction. The bolts  134  are inserted through the left and right end portions of horizontally long bolt insertion portions  131  in the up-down direction. The bolt insertion portion  131  extends forward from an upper side and a lower side of the nozzle attachment portion  106   b , separately. Nuts  135   a  and  135   b  are respectively disposed on left and right sides above and below the upper bolt insertion portion  131 , and are screwed to the bolts  134 . Nuts  135   c  and  135   d  are respectively disposed on the left and right sides above and below the lower bolt insertion portion  131 , and are screwed to the bolts  134 . 
     The spring  136  is disposed between the nut  135   b  and the upper portion of the bulging portion  132   a , and the spring  137  is disposed between the lower portion of the bulging portion  132   a  and the nut  135   c . A lower end portion of the upper bolt  134  is inserted into an upper side of the spring  136 , and a lower side of the spring  136  is fixed to the bulging portion  132   a , thereby preventing the spring  136  from being detached. The upper side of the spring  137  is fixed to the bulging portion  132   a , and the upper end portion of the lower bolt  134  is inserted into the lower side of the spring  137 , thereby preventing the spring  137  from being detached. 
     The nozzle  107  is fixed to the slider  132 , and the nozzle  107  is displaced in accordance with the displacement of the slider  132  in the up-down direction. Specifically, as the lifting body of the horizontal moving unit  105  is raised and lowered (displaced), the nozzle attachment portion  106   b  fixed to the lifting body is raised and lowered (displaced). Here, the slider  132  slidably attached to the nozzle attachment portion  106   b  does not slide, and a position of the slider  132  on the nozzle attachment portion  106   b  does not change in a state where the springs  136  and  137  are attached up and down and no load is applied to the nozzle  107 . On the other hand, when the nozzle  107  is pressed against the object via the threadlike adhesive  2 , an elastic force in a direction opposite to the pressing direction is generated in the springs  136  and  137 . That is, the springs  136  and  137  absorb the displacement of the nozzle  107  with respect to the displacement of the nozzle attachment portion  106   b . As a result, it is possible to control a force (pressing force) with which the nozzle  107  presses the threadlike adhesive  2  against the object, and to prevent the pressing force from excessively increasing or rapidly increasing. Therefore, it is possible to prevent a large deformation of the threadlike adhesive  2 , that is, a problem such as sticking out of the adhesive (lowering of adhesion width accuracy) or unevenness of the height of the threadlike adhesive  2  due to an excessively strong pressing force, and to appropriately express the adhesive force of the threadlike adhesive. In addition, it is possible to protect the apparatus by preventing an excessive load from being applied to the nozzle  107 . 
     In this way, the springs  136  and  137  function as an absorption mechanism that absorbs the displacement of the nozzle  107  with respect to the displacement of the nozzle attachment portion  106   b , and gently change the pressing force. Therefore, even in a case where a height of an adhesive surface of the object changes depending on the accuracy or in a case where the adhesive surface of the object is not smooth and has unevenness, the above-described problem can be prevented. In addition, even in a portion where the threadlike adhesive  2  overlaps in the sticking path, the threadlike adhesive  2  can be smoothly stuck over the stuck threadlike adhesive  2  by the function of the springs  136  and  137 . Instead of the springs  136  and  137 , an oil damper or an air cylinder may be attached between the nozzle attachment portion  106   b  and the nozzle  107  to function as an absorption mechanism. The pressing mechanism BU described above is merely an example. The pressing mechanism BU may have another configuration such that the nozzle  107  is movable in the up-down direction, and includes an absorption mechanism that absorbs the displacement of the nozzle  107  with respect to the displacement of the base to which the nozzle  107  is attached in the up-down direction. 
     The air chuck  108  and the air scissor  109  are attached to the nozzle attachment portion  106   b  on the left and right sides of the nozzle  107 , respectively (see  FIG.  6    and  FIG.  7   ). When the sticking of the threadlike adhesive  2  is completed, the air chuck  108  and the air scissor  109  are separately moved from a normal position shown in  FIG.  6    and  FIG.  7    to a position shown in  FIG.  8    by a driving unit. The air chuck  108  is moved obliquely from the normal position to the lower right, and chucks the threadlike adhesive  2  immediately below the nozzle  107 . The air scissor  109  is moved downward from the normal position and then moved leftward to cut the chucked threadlike adhesive  2  immediately below the air chuck  108 . Since the air chuck  108  and the air scissor  109  are attached to the lifting body of the horizontal moving unit  105  via the attachment plate  106  similarly to the nozzle  107 , the air chuck  108  and the air scissor  109  can be moved together with the nozzle  107  while maintaining the positional relationship with respect to the nozzle  107 . The air chuck  108   and the air scissor  109  are not limited in shape, driving method, and the like as long as they can hold and cut the threadlike adhesive  2  at predetermined positions. In addition, instead of the air scissor  109 , the threadlike adhesive  2  may be baked and cut by heat cutting using a heat cutter or the like. 
     In the threadlike adhesive sticking apparatus  101 , the threadlike adhesive  2  supplied from the supply unit AU is pressed against the adherend by the nozzle  107 , the springs  136  and  137 , the lifting body of the horizontal moving unit  105 , and the attachment plate  106 . That is, the nozzle  107 , the springs  136  and  137 , the lifting body of the horizontal moving unit  105 , and the attachment plate  106  function as the pressing mechanism BU. 
     Operation of Threadlike Adhesive Sticking Apparatus  101  and Method of Sticking Threadlike Adhesive 
     Using the threadlike adhesive sticking apparatus  101  configured as described above, an operator who sticks the threadlike adhesive  2  to an object first places the object on a stage. At the start of the operation, the threadlike adhesive  2  supplied from the winding body to the nozzle  107  is led out to the outside from the tip end  107   d  of the nozzle  107 , and the operator presses the tip end into a predetermined position on the object. A relative position of the nozzle  107  with respect to the object is subjected to movement control by a control apparatus (movement control unit) (not shown) in accordance with a program set in advance. The program includes instructions such as a movement path, a movement speed, and a movement amount (a magnitude of a pressing force) in the Z direction of the nozzle  107  in the XY plane. When the movement of the nozzle  107  is started according to the program, the threadlike adhesive  2  is fed out from the winding body by an adhesive force of the threadlike adhesive  2  with respect to the object. The nozzle  107  presses the adhesive surface of the fed out adhesive surface  2 , and the threadlike adhesive  2  is pressed against and stuck (pressure-bonded) to the object along a predetermined path while the nozzle  107  slides on the adhesive surface. After the sticking is completed, the threadlike adhesive  2  is cut at a predetermined position by the air chuck  108  and the air scissor  109 . 
       FIG.  11    is a conceptual diagram showing a mode in which the nozzle  107  is moved on the object. Not only when the nozzle  107  goes straight as shown by an arrow L 1 , but also when a curve shown by an arrow L 2  is extremely bent (bent at a steep angle), the threadlike adhesive sticking apparatus  101  can stick the threadlike adhesive  2  with high accuracy. In the threadlike adhesive sticking apparatus  101 , since the entire circumference (a plurality of any positions in the peripheral portion) surrounding the tip end opening  107   c  in the tip end  107   d  of the nozzle  107  functions as a pressing unit that presses the threadlike adhesive  2  against the object, the moving direction can be easily changed. Therefore, the threadlike adhesive sticking apparatus  101  can stick the threadlike adhesive  2  along a predetermined sticking path with high accuracy. Since the threadlike adhesive sticking apparatus  101  does not use a roller or the like as the pressing unit, it is possible to prevent problems such as poor sticking accuracy due to the movement of the adhesive within the width of the roller, and detachment of the adhesive from the roller depending on the sticking path, in the case where the adhesive is pressed by the roller. 
     When sticking the threadlike adhesive  2  to the object along a predetermined path, the threadlike adhesive sticking apparatus  101  (movement control unit) may press the nozzle  107  more strongly at a desired position, that is, increase a downward displacement amount of the nozzle attachment portion  106   b  in the Z-axis direction (approach the object). Even when the nozzle attachment portion  106   b  is momentarily lowered, it is possible to appropriately increase the force with which the nozzle  107  presses the threadlike adhesive  2  and to increase the adhesive force of the threadlike adhesive  2  at a desired position since the nozzle  107  is gently lowered by the springs  136  and  137  (absorption mechanism). In addition, the threadlike adhesive sticking apparatus  101  (movement control unit) may stop the movement in the XY plane (fix the position of the nozzle  107  with respect to the object) while pressing the nozzle  107  for several seconds at the desired position. By not moving a plane position of the nozzle  107  while pressing the nozzle  107 , it is possible to increase a pressing time of the threadlike adhesive  2  and to increase the adhesive force of the threadlike adhesive  2  at a desired position. In a case where the threadlike adhesive  2  is stuck while being fed out from a winding body  120 , the threadlike adhesive  2  is easily peeled off at a start point (initial stage of sticking) of a predetermined path, a start point or an end point of a curve included in the predetermined path, a vertex of a corner included in the predetermined path, or the like. Therefore, at these positions, by lowering the nozzle  107  or stopping the nozzle  107  for several seconds while pressing the nozzle  107 , it is possible to increase the adhesive force of the threadlike adhesive  2  and prevent peeling. 
      Feed Out Assist Mechanism 
     An example in which a feed out assist mechanism is provided in the supply unit AU will be described with reference to  FIG.  12    to  FIG.  17   . The feed out assist mechanism applies an external force in a feeding direction to the threadlike adhesive  2  fed out from the winding body  120 . By applying the external force in the feeding direction by the feed out assist mechanism, it is possible to smoothly feed out the threadlike adhesive  2  from the winding body  120  against a self-adhesion force between the threadlike adhesives  2  wound around the winding body  120  even when the threadlike adhesive does not have a release liner. Therefore, the threadlike adhesive  2  can be pressed against the object in a state where the tension of the threadlike adhesive  2  is reduced. Therefore, it is possible to prevent a problem that the threadlike adhesive  2  pressed against the object is peeled off, cut, re-stuck, and entangled by tension, and to smoothly stick the threadlike adhesive  2 . 
     Feed out assist mechanisms  150 A,  150 B,  150 B a , and  150 C shown in  FIG.  12    to  FIG.  15    are provided in a path for conveying the threadlike adhesive  2  from the winding body  120  to the pressing mechanism BU, and apply, to the threadlike adhesive  2 , tensile forces (arrows F 1  to F 3 ) for pulling the threadlike adhesive  2  sandwiched therebetween in the feeding direction. 
     The feed out assist mechanism  150 A shown in  FIG.  12    includes a roller  151  (first roller), a roller  152  (second roller), a spring  153  (elastic body), and a spring attachment portion  154 . The roller  151  is a feed out roller that is driven and rotated by a motor (not shown). The roller  152  sandwiches the threadlike adhesive  2  with the roller  151 , is rotated in conjunction with the rotation of the roller  151 , and clamps and pulls out the threadlike adhesive  2  in a direction of an arrow F 1  (rotation direction). The spring  153  is attached between the roller  151  and the spring attachment portion  154 , and the spring attachment portion  154  is fixed in the apparatus. The spring  153  can adjust the tensile force of the rollers  151  and  152 . Further, by controlling the rotation of the roller  151 , it is possible to feed out the threadlike adhesive  2  in accordance with a sticking distance (moving distance of the nozzle  107 ). The rollers  151  and  152  may be configured to be movable in the left-right direction (direction intersecting the direction of the arrow F 1 ) without providing the spring  153 . 
      The feed out assist mechanism  150 B shown in  FIG.  13    has a roller  155  (third roller), a roller  156  (fourth roller), and a roller  157  (fifth roller). The rollers  155  and  156  can chuck and release the threadlike adhesive  2  therebetween. The roller  157  is disposed between the winding body  120  and the rollers  155  and  156 , and can be displaced so as to lengthen a path from the winding body  120  to the rollers  155  and  156  via the roller  157 . When the roller  157  is displaced so as to lengthen this path, the threadlike adhesive  2  is pulled and fed out from the winding body  120  in a direction of an arrow F 2 . The fed out threadlike adhesive  2  is chucked by the rollers  155  and  156  and supplied to the pressing mechanism BU (nozzle  107 ). Then, when the chuck by the rollers  155  and  156  is released, the pressing mechanism BU presses the threadlike adhesive  2  against the object. While the chuck by the rollers  155  and  156  is released, the roller  157  returns to an original position. By controlling the displacement of the roller  157 , it is possible to feed out the threadlike adhesive  2  in accordance with the sticking distance (moving distance of the nozzle  107 ). In addition, when the threadlike adhesive  2  becomes insufficient during the sticking of the threadlike adhesive  2 , the threadlike adhesive  2  can be chucked again by the rollers  155  and  156 , and the roller  157  can be displaced to feed out the threadlike adhesive  2 . 
     The feed out assist mechanism  150 B a  shown in  FIG.  14    has rollers  165 ,  166 ,  167 ,  168  and an arm  169 . The roller  165  is a feed out roller that is driven and rotated by a motor (not shown). The roller  166  sandwiches the threadlike adhesive  2  with the roller  165 , is rotated in conjunction with the rotation of the roller  165 , and clamps and pulls out the threadlike adhesive  2  in a direction of an arrow F 2   a . The rollers  167  and  168  are provided between the rollers  165  and  166  and the pressing mechanism BU, and guide the threadlike adhesive  2  pulled out by the rollers  165  and  166  to the pressing mechanism BU. The arm  169  has one end to which the roller  167  is attached and the other end which is pivotally supported by a housing of the threadlike adhesive sticking apparatus  101  and to which a potentiometer for calculating the position of the roller  167  is attached. When the roller  167  is moved downward from a position shown in  FIG.  14    (is displaced so as to lengthen a path from the rollers  165  and  166  to the roller  168 ), a conveying speed of the threadlike adhesive  2  decreases. In this way, the threadlike adhesive  2  is fed out by the rollers  165  and  166 , and a rapid speed change of the fed out threadlike adhesive  2  can be alleviated by the displacement of the roller  167 . 
       FIG.  15    shows an example in which the feed out assist mechanism  150 C is provided in a threadlike adhesive sticking apparatus  101 A in a mode of being gripped and used by an operator. Members having the same functions as those of the threadlike adhesive sticking apparatus  101  are denoted by the same reference numerals. The threadlike adhesive sticking apparatus  101 A includes the supply unit AU (winding body  120 ) and the feed out assist mechanism  150 C in a housing K 1  having a size and a shape that can be held by one hand of an operator, and has a nozzle  107 A at a tip end of the housing K 1 . The feed out assist mechanism  150 C includes a roller  158  (first roller), a roller  159  (second roller), a spring  160  (elastic body), and a spring attachment portion  161 . The roller  158  is exposed to the outside of the housing K 1  from a portion of which a part is cut out in the housing K 1 , and is rotated by a finger M of the operator. The roller  159  sandwiches the threadlike adhesive  2  with the roller  158 , is rotated in conjunction with the rotation of the roller  158 , and clamps and pulls out the threadlike adhesive  2  in a direction of an arrow F 3  (rotation direction). The spring  160  is attached between the roller  159  and the spring attachment portion  161 , and the spring attachment portion  161  is fixed to an inner wall of the housing K 1 . A compression force (degree of collapse) to the threadlike adhesive  2  can be adjusted by the spring  160 . 
     The threadlike adhesive  2  pulled and fed out by the feed out assist mechanism  150 C is allowed to pass through the cylindrical internal space of the nozzle  107 A at the tip end of the housing K 1  with low tension, and is led out to the outside of the housing K 1 . The nozzle  107 A is formed of the same material as that of the nozzle  107 , and a tip end opening thereof has a circular shape or a polygonal shape having five or more corners. In addition, the nozzle  107 A presses the threadlike adhesive  2 , which has been allowed to pass through the cylindrical internal space and has been led out to the outside, against the object at the entire circumference or at a plurality of any positions of the peripheral portion surrounding the tip end opening. That is, the operator holding the housing K 1  can stick the threadlike adhesive  2  to the object in any path by pressing the nozzle  107 A against the object while rotating the roller  158  with the finger M using the threadlike adhesive sticking apparatus  101 A, just like operating a writing instrument such as a pen. 
     Feed out assist mechanisms  150 D and  150 E shown in  FIG.  16    and  FIG.  17    apply, to the threadlike adhesive  2 , an extrusion force for feeding out the threadlike adhesive  2  by rotating the winding body  120  in the feeding direction. 
     The feed out assist mechanism  150 D shown in  FIG.  16    includes a surface drive SD and winding body holding rods  162 , and holds the winding body  120  in place of the winding body holding unit of the threadlike adhesive sticking apparatus  101 . The surface drive SD comes into contact with the threadlike adhesive  2  wound around the winding body  120  or the outer peripheral surface of the winding body  120 , and rotatably holds the winding body  120 . The surface drive SD is rotationally driven by a motor (not shown) to rotate the winding body  120  in the feeding direction indicated by an arrow F 4 . The winding body holding rods  162  are disposed on both end sides of the winding body  120 , and hold the winding body  120  held by the surface drive SD so as to be rotatable and prevent the winding body  120  from falling off from the surface drive SD. The threadlike adhesive  2  is supplied to the pressing mechanism BU at a low tension by the feed out assist mechanism  150 D that applies an extrusion force to the threadlike adhesive  2  by rotating the winding body  120 . 
       FIG.  17    shows an example in which the feed out assist mechanism  150 E is provided in a threadlike adhesive sticking apparatus  101 B in a mode of being gripped and used by an operator. Members having the same functions as those of the threadlike adhesive sticking apparatus  101  are denoted by the same reference numerals. The threadlike adhesive sticking apparatus  101 B includes the supply unit AU (winding body  120 ) and the feed out assist mechanism  150 E in a housing K 2  having a size and a shape that can be held by one hand of an operator, and has a nozzle  107 B at a tip end of the housing K 2 . The feed out assist mechanism  150 E has a gear  163  and a roller  164 . The gear  163  is attached to the supply unit AU (winding body  120 ) and rotated together with the winding body  120 . The gear  163  is exposed to the outside of the housing K 2  from a portion K 21  of which a part is cut out in the housing K 2 , and is rotated by a finger M of the operator. When the gear  163  is rotated by the finger M, an extrusion force is applied to the threadlike adhesive  2 . The extruded threadlike adhesive  2  is guided by the roller  164  to reach the nozzle  107 B, is allowed to pass through the cylindrical internal space of the nozzle  107 B with low tension, and is led out to the outside of the housing K 2 . The nozzle  107 B has the same configuration as the nozzle  107 A. The nozzle  107 B presses the threadlike adhesive  2 , which has been allowed to pass through the cylindrical internal space and has been led out to the outside, against the object at the entire circumference or at a plurality of any positions of the peripheral portion surrounding the tip end opening. Therefore, the operator holding the housing K 2  can draw any path by pressing the nozzle  107 B against the object while rotating the gear  163  with the finger M. Therefore, the operator can stick the threadlike adhesive  2  to the object in any path (in various shapes) using the threadlike adhesive sticking apparatus  101 B, just like operating a writing instrument such as a pen. Instead of the feed out assist mechanism  150 E shown in  FIG.  17   , the movement of the nozzle  107 B (pressing of the threadlike adhesive  2  by the nozzle  107 ) may be transmitted to a core (rotation shaft) of the winding body  120  by a belt formed of rubber or the like to assist the feeding out of the threadlike adhesive  2 . In addition, the feeding out of the threadlike adhesive  2  may be assisted by directly rotating the core of the winding body  120 . 
     It is preferable that a member such as a roller for applying tension to the threadlike adhesive  2  does not exist in a path for conveying the threadlike adhesive  2  between the feed out assist mechanisms  150 A,  150 B,  150 B a ,  150 C,  150 D, and  150 E, the pressing mechanism BU (nozzle  107 ), and the nozzles  107 A and  107 B. In addition, in the threadlike adhesive sticking apparatus  101 , a tension detector may be provided in a path for conveying the threadlike adhesive  2 , and the feed out assist mechanisms  150 A,  150 B, and  150 D may be controlled according to a detected tension value to feed out the threadlike adhesive  2  so as to have a constant tension. Further, in the above embodiment, an example in which the threadlike adhesive  2  is stuck to the adherend placed on the stage is shown, but the threadlike adhesive  2  can be stuck to an adherend having a three-dimensional shape such as a curved surface by attaching the nozzle  107  to an articulated robot arm having a degree of freedom of six axes, for example. 
     Second Embodiment 
       FIG.  18    is a schematic view showing a threadlike adhesive sticking apparatus according to a second embodiment of the present invention. As shown in  FIG.  18   , a threadlike adhesive sticking apparatus  100  of the present embodiment includes a main body  1  having a shaft shape, and a tip end portion  4  detachably provided at both ends of the main body  1 . The main body  1  is provided with a grip  3  formed of a resin or the like. 
     An operator grips the threadlike adhesive sticking apparatus  100  at the portion of the grip  3 , presses the tip end portion  4  against an object which is an adherend of the threadlike adhesive  2 , and moves the tip end portion  4  in one direction, whereby the threadlike adhesive  2  can be fed out. That is, the operator can use the threadlike adhesive sticking apparatus  100 , just like operating a writing instrument such as a pen, while gripping (grip  3  of) the elongated main body  1  having a shaft shape. For example, the operator can operate the threadlike adhesive sticking apparatus  100  as expected even in a narrow location or the like with many obstacles, and can efficiently perform various operations. 
     The main body  1  has a shaft shape extending in a uniaxial direction. An internal space S having a shaft shape is defined inside the main body  1  as shown in  FIG.  18   . The tip end portion  4  having a tapered shape is detachably attached to one end (tip end) of the main body  1 . A shape of the tip end portion  4  may be a shape having a cylindrical pipe at the tip of the tapered shape, like a tip of a mechanical pencil. A tip end opening  4   a  is formed at the tip end of the tip end portion  4 , and the internal space S of the main body  1  communicates with the outside through the tip end opening  4   a  (tubular internal space). The tip end portion  4  is defined by a region from a position P 1  ( FIG.  18   ) where a cross-sectional area thereof is smaller than that of the main body  1  to the tip end opening  4   a . At the other end (rear end) of the main body  1 , a winding body capable of winding the threadlike adhesive  2  is attached inside. 
     In the present embodiment, since the tip end portion  4  has a tapered shape of which a cross section becomes smaller toward the tip end, workability in a narrow location is improved. In addition, in a case where the tip end portion  4  has a cylindrical pipe at the tip of the tapered shape, as the pipe is thinner and longer, workability in a narrower location is improved.  FIG.  19 A  and  FIG.  19 B  are views showing an example of the cross-section of the tip end portion  4  as viewed from a tip end opening  4   a  side, in which  FIG.  19 A  shows the tip end portion  4  having a circular cross-section and  FIG.  19 B  shows the tip end portion  4  having a pentagonal cross-section. Since a plurality of portions of the peripheral portion of the tip end opening  4   a  having a circular cross-sectional shape or a polygonal cross-sectional shape having five or more sides function as the pressing unit, the sticking direction can be easily changed. An overall shape of the tip end portion  4  is not particularly limited, and examples thereof include a conical shape, a quadrangular pyramid shape, and a fountain pen tip shape (saucer shape). The overall shape of the tip end portion  4  may be an extremely elongated straw shape. 
      A length of the tip end portion  4  shown in  FIG.  18    is preferably 3 mm or more, and more preferably 10 mm or more. A width W of the tip end portion  4  shown in  FIG.  19    is defined by a position where the cross-sectional area of the tip end portion  4  is the smallest, but the width W also corresponds to an inner diameter (diameter) of the tip end portion  4 . The minimum cross-sectional area of the tip end portion  4  is preferably in a range of 1.2 to 9 times the cross-sectional area of the threadlike adhesive  2 . Therefore, for example, in a case where the cross-section of the threadlike adhesive  2  has a circular shape having a diameter of 0.3 mm, the size of the width W of the tip end portion  4  is set in a range of about 0.32 mm to 0.9 mm. Such a size is expected to improve workability. In addition, in the threadlike adhesive sticking apparatus  100 , the unnecessary movement of the threadlike adhesive  2  is restricted by the tip end opening  4   a  of the tip end portion  4 . Therefore, without using a roller or the like as the pressing unit, the operator can grip the threadlike adhesive sticking apparatus  100  at the portion of the grip  3  and stick the threadlike adhesive  2  while moving the tip end portion  4  in a plurality of any directions. Therefore, in a case where the adhesive is pressed by the roller, it is possible to prevent a problem that the adhesion accuracy is poor due to the movement of the adhesive within a roller width, and the adhesive is detached from the roller depending on an adhesion path, and thus it is possible to accurately stick the threadlike adhesive. Further, in the case where the tip end portion  4  has a cylindrical pipe at the tip of the tapered shape, as the pipe is thinner and longer, workability in a narrower location is improved. 
     Third Embodiment 
       FIG.  20    is a perspective view showing an internal structure of a threadlike adhesive sticking apparatus  100  according to a third embodiment. In the present embodiment, at the other end (rear end) of the main body  1 , a winding body  5  capable of winding the threadlike adhesive  2  is rotatably attached with a direction perpendicular to an axial direction of the main body  1  as an axis. Since the threadlike adhesive  2  is allowed to pass through the internal space S and goes out from the tip end opening  4   a , unnecessary movement is restricted. Further, since a plurality of portions of the peripheral portion of the tip end opening  4   a  function as the pressing unit, a sticking direction can be easily changed. 
     Fourth Embodiment 
       FIG.  21    is a schematic front view showing a main part of a threadlike adhesive sticking apparatus  200  according to a fourth embodiment. The threadlike adhesive sticking apparatus  200  is different from the threadlike adhesive sticking apparatus  101  according to the first embodiment in configurations of the pressing mechanism BU and the conveyance unit CU and a configuration for reducing an extra length of the threadlike adhesive  2  at the time of cutting. Hereinafter, differences from the first embodiment will be mainly described, and redundant description will be omitted. 
     In the threadlike adhesive sticking apparatus  200 , main parts of the pressing mechanism BU and the conveyance unit CU are attached to front of an attachment plate  201  having a substantially rectangular shape, and are positioned by the positioning unit DU. 
     Conveyance Unit CU of Threadlike Adhesive Sticking Apparatus  200   
     The threadlike adhesive sticking apparatus  200  includes a roller  122  (see  FIG.  5   ), rollers  202 ,  203 , and  204 , a moving unit  205 , an arm  206 , rollers  207 ,  208 , and  209 , a moving unit  210 , a roller  211 , and a moving unit  212  as an example of the conveyance unit CU, and conveys the threadlike adhesive  2  fed out from the supply unit AU (winding body) to the nozzle  107 . 
     The rollers  202 ,  203 ,  204 ,  207 ,  208 ,  209 , and  211  are configured similarly to the above-described roller  122  and the like, and are rotatably attached to the attachment plate  201  directly or indirectly, in a perpendicular plane (YZ plane). As an example, the rollers  202 ,  203 ,  204 ,  207 ,  208 ,  209 , and  211  are disposed such that respective rotation positions are at substantially the same distance from the front surface side of the attachment plate  201  (front side of the paper surface in  FIG.  21   ). 
     The roller  202  is attached to an upper left corner of the attachment plate  201 , and guides the threadlike adhesive  2  to the rollers  203  and  204 . On the left side of the roller  202 , and on the right side of the roller  122  in the frame erected on the left side of the winding body holding unit  121 , a roller capable of being moved up and down according to the tension of the threadlike adhesive  2  to be conveyed and a roller provided on the upper right side of the roller (both not shown) may be disposed. The tension of the threadlike adhesive  2  supplied to the roller  202  can be adjusted to be constant by these rollers. 
      The roller  203  is attached to the attachment plate  201  slightly below the right side of the roller  202 . The roller  203  is a feed out roller that is driven and rotated by a motor (not shown). 
     The roller  204  is disposed on the upper right of the roller  203 , and is attached to a lower left end portion of the moving unit  205  such as an air cylinder that is moved (slides) in a direction of an arrow D 1  (upper right and lower left directions) with respect to the attachment plate  201 . When the roller  204  is located at the lowest left, the roller  204  is rotated in conjunction with the rotation of the roller  203 , sandwiches the threadlike adhesive  2  with the roller  203 , and pulls out the threadlike adhesive  2  in a direction of an arrow F 5 . 
     The arm  206  is a rod-shaped body extending in the left-right direction below the rollers  202  and  203  and the moving unit  205 . The roller  207  is attached to the right end portion of the arm  206 . A vicinity of the left end portion of the arm  206  is rotatably supported to the attachment plate  201  by a rotation shaft  206   a . A potentiometer for calculating a position of the roller  207  is attached to the rotation shaft  206   a . The arm  206  is rotated in a direction of an arrow D 2  (substantially in up-down direction) by a drive unit such as a motor provided on the rear side of the attachment plate  201 , for example. That is, the roller  207  is movable in the up-down direction by the rotation of the arm  206 . 
     A shaft  206   b , which extends along an extending direction of the arm  206  and is provided with a spiral ridge on the outer peripheral surface thereof, protrudes from the left end portion of the arm  206 . One or more weights  206   c  are attached to the shaft  206   b . The weight  206   c  has a substantially disc shape, and a through hole provided at the center of the weight  206   c  is formed with a groove to be screwed with the spiral ridge of the shaft  206   b . The ease of movement of the arm  206  can be controlled by changing a distance between the weight  206   c  and the rotation shaft  206   a  (left end portion of the arm  206 ) by shifting the position of the weight  206   c  on the shaft  206   b . 
     The roller  208  is attached to the upper right of the roller  207  and the right side of the roller  204  in the attachment plate  201 . The roller  208  guides the threadlike adhesive  2  pulled out by the rollers  203  and  204  to, via the roller  207 , the pressing mechanism BU (nozzle  107 ) provided immediately below the roller  208 . 
      When the roller  207  is moved downward (displaced so as to lengthen a path from the rollers  203  and  204  to the roller  208 ), a conveying speed of the threadlike adhesive  2  decreases. In this way, the threadlike adhesive  2  is fed out by the rollers  203  and  204 , and a rapid speed change of the fed threadlike adhesive  2  can be alleviated by the displacement of the roller  207 . That is, the rollers  203 ,  204 ,  207 , and  208  and the arm  206  function as the feed out assist mechanism  150 B a  shown in  FIG.  14   . 
     Reduction of Extra Length in Threadlike Adhesive Sticking Apparatus  200   
     On the right side of the roller  208 , i.e., above the nozzle  107 , a roller  209  attached to a left end portion of the moving unit  210  that is moved in a direction of an arrow D 3  (left-right direction) with respect to the attachment plate  201  is disposed. The roller  209  is disposed adjacent to the roller  203  so that the threadlike adhesive  2  can be nipped between the roller  209  and the roller  208  when being positioned at the leftmost position. The roller  209  provided upstream of the nozzle  107  nips (chucks) the threadlike adhesive  2  with the roller  208  when the sticking of the threadlike adhesive  2  is completed and the nozzle  107  is raised. In this state, the threadlike adhesive  2  is cut at a position close to an adherend H. 
     In the first embodiment, the threadlike adhesive  2  is chucked below (downstream of) the nozzle  107  by the air chuck  108 , whereas in the present embodiment, the roller  209  is provided upstream of the nozzle  107 , and the threadlike adhesive  2  is chucked with the roller  208  that conveys the threadlike adhesive  2 . With this configuration, since the space for the air chuck  108  below the nozzle  107  can be reduced, the extra length at the time of cutting (end point) can be reduced. 
     The roller  211  is disposed below the rollers  208  and  209  and the moving unit  210 , that is, above the nozzle  107 , and is attached to the left end portion of the moving unit  212  that is moved in a direction of an arrow D 4  (left-right direction) with respect to the attachment plate  201 . As an example, when the roller  211  is positioned on the right side, the roller  211  allows the threadlike adhesive  2  to pass therethrough and guides the threadlike adhesive  2  into the nozzle  107 , and when the threadlike adhesive  2  is cut, the roller  211  is moved to the left side to press the threadlike adhesive  2  in a left direction, and moves the cut tip end portion (lower end portion) of the threadlike adhesive  2  upward. By raising the lower end portion of the threadlike adhesive  2  after cutting the threadlike adhesive  2 , it is possible to reduce the extra length at the start of the next sticking of the threadlike adhesive  2  (start point). When allowing the threadlike adhesive  2  to pass through the right side of the roller  211 , the roller  211  is moved to the right side to pull the threadlike adhesive  2  in a right direction, so that the lower end portion of the threadlike adhesive  2  can be moved upward. 
     The extra length of the threadlike adhesive  2  may be reduced by rotating the roller  203  or the like in a reverse direction, but there is a concern that the threadlike adhesive  2  may be wound around the roller  203  or the like due to the reverse rotation and may not be wound around the winding body. In this regard, as described above, by nipping and cutting the threadlike adhesive  2  by the rollers  208  and  209  and then raising the lower end portion of the threadlike adhesive  2  by the roller  211 , it is possible to reduce the extra length of the end point and the start point without the above-described problem. 
     A guide rod (not shown) erected on the front of the attachment plate  201  may be provided below the roller  211 . A surface (outer peripheral surface) of the guide rod is a non-adhesive surface, and thus it is possible to restrict the displacement of the threadlike adhesive  2  in the left direction. 
     Pressing Mechanism BU of Threadlike Adhesive Sticking Apparatus  200   
     The threadlike adhesive sticking apparatus  200  includes the nozzle  107 , a slider  213 , a fixing unit  214 , and a spring  215  as an example of the pressing mechanism BU, and sticks the threadlike adhesive  2  conveyed to the conveyance unit CU to the adherend H. The pressing mechanism BU is provided below the roller  211  and the moving unit  212  on the attachment plate  201 . 
     The nozzle  107  is fixed to the front of the slider  213 , and the tip end opening  107   c  can protrude from the lower end of the attachment plate  201 . The slider  213  is movable in the up-down direction with respect to the attachment plate  201  by a linear guide or the like. 
     In the attachment plate  201 , the fixing unit  214  is fixed above the slider  213 . The fixing unit  214  holds the spring  215 , in which a shaft inserted therein, with the upper surface of the slider  213 . 
      As described above, as in the first embodiment, the nozzle  107  of the present embodiment includes an absorption mechanism that is movable in the up-down direction and absorbs a displacement of the nozzle  107  with respect to a displacement of a base to which the nozzle  107  is attached in the up-down direction. 
     Further, the air scissor  109  (nipper) is disposed on the right side of the pressing mechanism BU in the attachment plate  201 . The air scissor  109  is moved obliquely to the lower left from a normal position by a driving unit, and cut the threadlike adhesive  2  immediately below the nozzle  107 . At this time, as described above, since the threadlike adhesive  2  is chucked above the nozzle  107  (by the rollers  208  and  209 ), the air chuck  108  becomes unnecessary. Therefore, a distance between the nozzle tip end  107   c  and the threadlike adhesive  2  attached to the adherend H can be reduced, and the extra length at the time of cutting (end point) can be reduced. 
     Improvement of Sticking With Short Extra Length 
     The movement of the nozzle  107  in the sticking start point creation when the extra length is short will be described with reference to  FIG.  22    and  FIG.  23   . In the case where the extra length is short at the start of sticking of the threadlike adhesive  2 , when the nozzle  107  is vertically lowered in a direction of an arrow N 1  shown in (a) of  FIG.  22   , the threadlike adhesive  2  may enter the inside of the nozzle  107 , as shown in (b) of  FIG.  22   , and the start point may not be attached to the adherend H. Therefore, when the nozzle  107  is lowered in an oblique direction (direction of an arrow N 2 ) from the state shown in (a) of  FIG.  23   , the start point can be created without the threadlike adhesive  2  entering the nozzle  107 , as shown in (b) of  FIG.  23   . 
     As described above, the threadlike adhesive sticking apparatus  200  includes the feed out assist mechanism (the rollers  203 ,  204 ,  207 , and  208  and the arm  206 ) and the configuration for reducing the extra length (the rollers  208  and  209  which chuck the threadlike adhesive  2  upstream of the nozzle  107 , and the roller  211  which presses/pulls the cut threadlike adhesive  2  upstream of the nozzle  107 ). According to this configuration, in addition to the same effect as that of the first embodiment, it is possible to convey the threadlike adhesive  2  at a low tension, and it is possible to reduce the extra length at the start and end of sticking. Therefore, the threadlike adhesive  2  can be stuck at high speed without waste. 
     Fifth Embodiment 
       FIG.  24    is a perspective view showing a threadlike adhesive sticking apparatus  200 A according to a fifth embodiment.  FIG.  25    is a front view showing a state where an opening/closing frame  235  is opened in the threadlike adhesive application device  200 A according to the fifth embodiment. The threadlike adhesive sticking apparatus  200 A mainly includes a main body frame  230 , a gripping portion  231 , and an opening/closing frame  235  in which a winding body  240  capable of winding the threadlike adhesive  2  is held. 
     In the main body frame  230 , a lower portion of an elongated plate member extending in the up-down direction is bent in an oblique direction to be tapered. The nozzle  107  is fixed to the bent portion of the main body frame  230 , and a pressing roller  232  is provided at the tapered lower end. As shown in  FIG.  25   , the nozzle  107  is attached along an axial direction of the main body frame  230 . In addition, the pressing roller  232  is disposed at a position slightly above the tip end opening  107   c  on the front side of the tip end opening  107   c  of the nozzle  107 . The pressing roller  232  is rotatably attached to the main body frame  230  in a vertical plane. The function of the pressing roller  232  will be described later. 
     A motor  233  and a roller  234  driven by the motor  233  are attached to substantially the center of the main body frame  230 . The roller  234  is rotatably attached to the opening/closing frame  235  in the vertical plane, and sandwiches the threadlike adhesive  2  with a roller  236  being rotated with the rotation of the roller  234  to feed out the threadlike adhesive  2  from the winding body  240 . That is, the rollers  234  and  236  function as a feed out assist mechanism. The motor is provided with a speed volume (not shown) for adjusting a rotation speed of the motor  233 , that is, for manually adjusting a feed out speed of the threadlike adhesive  2 . 
     The gripping portion  231  having a substantially rectangular plate shape is provided slightly below the center of the main body frame  230  so as to protrude rearward. The gripping portion  231  is gripped by an operator. The gripping portion  231  is provided with a switch  231 A for switching on/off of the motor  233  to start/stop feed out of the threadlike adhesive  2 . As an example, the switch  231 A is provided at a position where the operator can easily operate the switch  231 A with an index finger in a state where the operator grips the gripping portion  231 , turns on the motor  233  while the switch  231 A is pressed, and turns off the motor  233  when the switch  231 A is released from the pressing (that is, when the switch  231 A is not pressed). 
     The opening/closing frame  235  includes a roller holding unit  237  that rotatably holds the roller  236  in the vertical plane, and a winding body holding unit  238  that rotatably holds the winding body  240  in the perpendicular plane. The opening/closing frame  235  is pivotally supported by the main body frame  230  at the rear of the lower end side, and can be opened and closed with respect to the main body frame  230 . 
     In an open state shown in  FIG.  25   , the operator sets the winding body  240  in the winding body holding unit  238 , and inserts the threadlike adhesive  2  into the inside of the nozzle  107  via the rotation surface of the roller  236 . Then, the operator rotates the opening/closing frame  235 , on which the winding body  240  is set, rearward to close the opening/closing frame  235 , and engages the upper end of the opening/closing frame  235  with the main body frame  230  to bring the opening/closing frame  235  into a closed state shown in  FIG.  24   . 
     As shown in  FIG.  24   , the operator grasps the gripping portion  231  to bring the tip end (tip end opening  107   c ) of the nozzle  107  close to the adherend. At this time, in a case where the extra length of the threadlike adhesive  2  is short, the operator lowers the nozzle  107  in an oblique direction as shown in  FIG.  23   , so that the start point can be reliably created without the threadlike adhesive  2  entering the nozzle  107 . 
     When the operator operates the switch  231 A, the motor  233  is rotated, and the rollers  234  and  236  feed out the threadlike adhesive  2  from the winding body  240  by the rotation of the motor  233 . When the operator moves the nozzle  107  on the adherend in any direction, the threadlike adhesive  2  fed out from the winding body  240  is stuck to the adherend in any path. 
       FIG.  26    shows a state where the threadlike adhesive  2  is cut at the end of the sticking operation using the threadlike adhesive sticking apparatus  200 A. When the sticking operation ends, the operator operates (releases the pressing of) the switch  231 A to stop the rotation of the motor  233 . At an end point position, as shown in  FIG.  26   , the operator tilts the main body frame  230  with respect to a vertical direction, and presses the threadlike adhesive  2  against the adherend by the pressing roller  232 . By pressing the threadlike adhesive  2  with the pressing roller  232 , it is possible to prevent a stuck portion (end point of the threadlike adhesive  2 ) from being lifted and peeled off. 
     The operator cuts the threadlike adhesive  2  in the vicinity of the end point with a scissor  241  in a state where the end point is pressed by the pressing roller  232  as described above. Since the pressing roller  232  is provided in the vicinity of the nozzle  107 , the operator can prevent peeling of the end point of the threadlike adhesive  2  by a simple operation of merely tilting the threadlike adhesive attaching device  200 A (main body frame  230 ) while gripping the threadlike adhesive sticking apparatus  200 A. 
     As described above, according to the threadlike adhesive sticking apparatus  200 A of the present embodiment, although the workability in a narrow location is better in the threadlike adhesive sticking apparatus  100  of the second embodiment, similarly to the second embodiment, it is possible to easily change the sticking direction since a plurality of portions of the peripheral portion of the tip end opening  107   c  of the nozzle  107  function as the pressing unit. Therefore, the operator can stick the threadlike adhesive  2  while gripping the gripping portion  231  and moving the threadlike adhesive  2  in any direction. 
     Sixth Embodiment 
       FIG.  27    is a schematic view showing a threadlike adhesive sticking apparatus  200 B according to a sixth embodiment. The threadlike adhesive sticking apparatus  200 B includes an attachment plate  250 , rollers  251  and  252  provided on the attachment plate  250 , and the nozzle  107 . A winding body  260  capable of winding the threadlike adhesive  2  is rotatably held by the attachment plate  250  in a vertical plane. The threadlike adhesive sticking apparatus  200 B is a stationary sticking apparatus in which, for example, the attachment plate  250  is fixedly disposed and used on a table by a support frame. 
     The rollers  251  and  252  are disposed on a side (right side in  FIG.  27   ) of the winding body  260  on the front surface side of the attachment plate  250 . The roller  251  is driven by a motor provided on the rear side of the attachment plate  250 . The roller  252  sandwiches the threadlike adhesive  2  with the roller  251 , and is rotated with the rotation of the roller  251 . By the rotation of the rollers  251  and  252 , the threadlike adhesive  2  is fed out from the winding body  260 . The nozzle  107  is fixed below (directly below) the rollers  251  and  252  at the lower end of the attachment plate  250 . 
     The operator drives the motor to feed out the threadlike adhesive  2 , brings the adherend H into contact with the tip end opening  107   c  of the nozzle  107 , and sticks the threadlike adhesive  2  in any path while moving the adherend H. At the end of the sticking, the driving of the motor is stopped, and the threadlike adhesive  2  is cut by a scissor or the like. 
     As described above, according to the threadlike adhesive sticking apparatus  200 B according to the sixth embodiment, the operator can stick the threadlike adhesive  2  to the adherend H having a planar or three-dimensional shape in any path by gripping the adherend H and moving the adherend H while bringing the adherend H into contact with the tip end opening  107   c  of the nozzle  107 . 
     Details of Threadlike Adhesive  2   
       FIG.  28    shows a schematic view of the threadlike adhesive  2  used in the threadlike adhesive sticking apparatuses  100 ,  101  and the like according to the first to sixth embodiments. The threadlike adhesive  2  is constituted by a linear adhesive body including a linear core material  2   a  and an adhesive layer  2   b  that covers a surface of the core material  2   a  in a longitudinal direction. 
     The threadlike adhesive  2  is an elongated adhesive body and has a linear shape. The linear shape mentioned here is a concept including not only a straight line shape, a curved line shape, a polygonal line shape, and the like, but also a state in which a material can be bent in various directions and angles like a filament (i.e., a threadlike shape). In addition, the adhesive layer in the present specification also includes a linear adhesive layer. 
     Although a cross-sectional shape of the threadlike adhesive  2  in the present configuration example is a circular shape, the present embodiment is not limited thereto, and the cross-sectional shape may be an elliptical shape, a rectangular shape such as a quadrangular shape, or the like, in addition to the circular shape. 
     The adhesive layer  2   b  contains an adhesive formed of an adhesive composition. The adhesive is not particularly limited as long as the adhesive satisfies a gel fraction and an amount of a change in the gel fraction, and a known adhesive can be used. Examples of the adhesive include an acrylic-based adhesive, a rubber-based adhesive, a vinyl alkyl ether-based adhesive, a silicone-based adhesive, a polyester-based adhesive, a polyamide-based adhesive, a urethane-based adhesive, a fluorine-based adhesive, and an epoxy-based adhesive. Among these adhesives, an acrylic-based adhesive, a urethane-based adhesive, a silicone-based adhesive, a rubber-based adhesive, or a polyester-based adhesive is preferable, and an acrylic adhesive is particularly preferable from the viewpoint of adhesiveness. The adhesive may be used alone or in combination of two or more kinds thereof. The adhesive in this embodiment is preferably a pressure-sensitive adhesive that has adhesiveness at room temperatures and can be stuck to a surface of an adherend by a pressure generated when a surface of the adhesive and the surface of the adherend are brought into contact with each other. When the adhesive is a pressure-sensitive adhesive, the adhesive does not need to be heated and can be applied to an adherend that is sensitive to heat. 
     As the adhesive, either a solvent-type adhesive or a water-dispersible type adhesive can be used. The adhesive is preferably an adhesive obtained by performing crosslinking by drying (solvent volatilization) an adhesive composition and rapidly completing the crosslinking after drying. This is because new crosslinking does not increase after surfaces of adhesive layers come into contact with one another. Here, the adhesive is preferably a water-dispersible type adhesive, and more preferably a water-dispersible type acrylic adhesive because of high-speedily coating, being friendly to the environment, and a small influence on a base material or a core material (swelling or dissolution). 
     In the adhesive body having a core material, an adhesive layer may cover the entire surface of the core material (a surface in a longitudinal direction), or may cover only at least a part of the surface of the core material. Although an adhesive layer is typically formed to be continuous, the adhesive layer is not limited to such a form, and may be formed in a regular such as a dot pattern or a stripe pattern or random pattern. An end surface of the core material may or may not be covered with an adhesive layer. For example, when the adhesive body is cut during a producing process or during use, the end surface of the core material may not be covered with the adhesive layer. 
     As the core material used in the threadlike adhesive  2 , for example, a resin, a rubber, a foam, an inorganic fiber, a composite thereof, or the like can be used. Examples of the resin include: polyolefins such as polyethylene (PE), polypropylene (PP), an ethylenepropylene copolymer, and an ethylene-vinyl acetate copolymer; polyesters such as polyethylene terephthalate (PET); a vinyl chloride resin; a vinyl acetate resin; a polyimide resin; a polyamide resin; and a fluorine-based resin. Examples of the rubber include a natural rubber, and a synthetic rubber such as a urethane rubber. Examples of the foam include a foamed polyurethane and a foamed polychloroprene rubber. Examples of the fiber include a glass fiber, a carbon fiber, a metal fiber, a chemical fiber (a regenerated fiber, a semi-synthetic fiber, a synthetic fiber, etc.), and a natural fiber (a plant fiber, an animal fiber, etc.). A cross-sectional shape of the core material is not particularly limited, and is usually a cross-sectional shape corresponding to a cross-sectional shape of the adhesive body. 
     Examples of a material of the threadlike core material that can be used in the threadlike adhesive  2  include various polymer materials such as rayon, cupra, acetate, promix, nylon, aramid, vinylon, vinylidene, polyvinyl chloride, polyester, acryl, polyethylene, polypropylene, polyurethane, polychlal, and polylactic acid; glasses, carbon fibers, various rubbers such as natural rubber and synthetic rubber such as polyurethane; natural materials such as cotton and wool; and metal. As the form of the threadlike core material, for example, monofilaments, multifilaments, span yarns, finished yarns generally called textured yarn, bulky yarn and stretched yarn that have been subjected to crimping or bulking or combined yarns obtained by, for example, twisting those can be used. The cross-sectional shape is not limited to only a circle, and can be a rectangular shape such as a square shape, a star shape, an elliptical shape, a hollow shape, and the like. 
     The core material may contain various additives such as a filler (inorganic filler, organic filler or the like), an age resister, an antioxidant, a UV absorber, an antistatic agent, a lubricant, a plasticizer, and a coloring agent (pigments, dyes or the like) as necessary. A known or common surface treatment such as a corona discharge treatment, a plasma treatment or application of an undercoat agent may be performed on the surface of the core material. 
     A size of a cross-section of the core material is not particularly limited and may be appropriately selected depending on a purpose. For example, when the cross-sectional shape of the core material is a circular shape, a diameter of the cross-sectional shape of the core material is preferably 1 µm to 2000 µm, and more preferably 10 µm to 1000 µm from the viewpoint of handleability (flexibility, difficulty in cutting). 
     A thickness of the adhesive layer is not particularly limited, and is, for example, preferably 1 µm or more, and more preferably 3 µm or more from the viewpoint of adhesiveness. The thickness of the adhesive layer is, for example, preferably 200 µm or less, and more preferably 150 µm or less from the viewpoint of thickness unevenness and drying properties. Further, the thickness can be increased according to an application by stacking layers. 
     In particular, the threadlike adhesive  2  is preferably a pressure-sensitive adhesive body in which the adhesive forming the adhesive layer  2   b  has adhesiveness at room temperature and that can be stuck to a surface of an adherend by a pressure generated when a surface of the adhesive and the surface of the adherend are brought into contact with each other. When the adhesive body is a pressure-sensitive adhesive body, the adhesive body does not need to be heated and can be applied to an adherend that is sensitive to heat. 
     As described above, the shape of the threadlike adhesive  2  is not particularly limited. The larger a ratio (major axis/minor axis) of a length of the major axis (the longest axis that passes through the center of gravity of the cross-sectional shape) to a length of the minor axis (the shortest axis that passes through the center of gravity of the cross-sectional shape) of the cross-sectional shape of the threadlike adhesive  2  is, the flatter the shape of the threadlike adhesive  2  is. On the other hand, as the ratio becomes smaller, the cross-sectional shape of the threadlike adhesive  2  comes close to a circular shape. When the cross-sectional shape of the threadlike adhesive  2  is a circular shape, the ratio has a minimum value of  1 . When the ratio has a minimum value of  1 , the cross-sectional shape of the threadlike adhesive  2  also includes a special shape such as a triangle and a star shape. 
     The threadlike adhesive  2  may have a release liner. When the threadlike adhesive  2  has a release liner, the release liner is released from the adhesive layer before the threadlike adhesive  2  reaches the nozzle  107  or the like, and the adhesive body is stuck to the object. Since the threadlike adhesive  2  has the release liner, the self-adhesion force of the adhesive can be reduced, and thus the threadlike adhesive  2  can be pressed against an object in a state where the tension of the threadlike adhesive  2  is reduced. Therefore, it is possible to prevent a problem that the threadlike adhesive  2  pressed against the object is peeled off, cut, re-stuck, and entangled by tension, and to smoothly stick the threadlike adhesive  2 . 
     Embodiments and usage methods of the threadlike adhesive  2  are roughly classified into the following four patterns. Here, a non-adhesive layer is a layer that covers a surface (a surface in the longitudinal direction) of the adhesive body, and the non-adhesive layer includes, for example, a layer that covers the adhesive body in an initial state before stretching and is cut out by stretching the adhesive body to exhibit adhesiveness of the adhesive body. A type, a material, and the like of the non-adhesive layer are not particularly limited. 
     1) An adhesive body without a non-adhesive layer is directly pressure-bonded.   2) An adhesive body without a non-adhesive layer + a release liner (the release liner is released before pressure-bonding)   3) An adhesive body covered with a non-adhesive layer   4) An adhesive body covered with a non-adhesive layer + a release liner (the release liner is released before pressure-bonding)   

     Further, the threadlike adhesive  2  of the present embodiment has flexibility and has a threadlike shape that can be bent in various directions and angles like a filament. The adhesive body having flexibility, in particular, an adhesive body having a threadlike shape, has an advantage in that the adhesive body can be easily applied to complicated shapes such as a curved line, a curved surface, and unevenness in addition to the effects described above. 
     For example, when an adhesive tape is stuck to an adherend having a part with a complicated shape such as a curved line, a curved surface, or an uneven shape, a wrinkle or overlapping may occur in the adhesive tape in such a part, and it is difficult to finely stick the adhesive tape while preventing a protrusion. The part where a wrinkle or overlapping occurs may cause a decrease in the adhesive strength. In order to stick the adhesive tape while preventing the occurrence of a wrinkle or overlapping, it is conceivable to stick the adhesive tape while finely cutting the adhesive tape. However, workability significantly deteriorates. On the other hand, an adhesive body having flexibility, in particular, a threadlike adhesive body can be firmly stuck without causing a wrinkle or overlapping even when being stuck to a part having a complicated shape such as a curved line, a curved surface, and an uneven shape. Further, since such an adhesive body can be stuck to a part to be stuck at one time, that is, in one step, the adhesive body is excellent in workability and can be applied to an automation line. 
     Specific examples of an application of the threadlike adhesive body include an application to fix cables such as electric wires or optical fibers, optical fiber sensors such as LED fiber light and Fiber Bragg Gratings (FBG), various wire members (linear members) such as a yarn, a string, and a wire, and a narrow member, in a desired form. For example, even in a case where a wire member or a narrow member is fixed to another member in a complicated shape, the threadlike adhesive body can be firmly fixed with excellent workability while preventing protrusion, wrinkles, and overlapping in accordance with the complicated shape that the wire member or the narrow member have. In a case where the wire member or the narrow member is fixed to another member, the threadlike adhesive body is stuck in advance in accordance with a form in which the wire member or the narrow member is to be fixed on a surface of the other member, and then, the wire member or the narrow member can be bonded and fixed in accordance with the adhesive body stuck to the surface of the other member. Alternatively, the threadlike adhesive body is stuck to a wire member or a narrow member, and then, the wire member or the narrow member may be fixed to another member in a desired form. 
     The threadlike adhesive body can also be suitably used for temporary fixing (temporary tacking) of an article for temporarily fixing (temporarily tacking) one article to a surface of another article. More specifically, the threadlike adhesive body can be particularly suitably used for temporary fixing (temporary tacking) in producing, for example, fiber products and leather products such as clothes, shoes, bags, and hats. However, the application is not limited to this example, and the threadlike adhesive body is suitably used for various applications in which temporary fixing (temporary tacking) is desired. 
     For example, when one article is fixed to a surface of another article, the one article is temporarily fixed and positioned on the surface of the other article in advance using the threadlike adhesive body, and then both articles are fixed (finally fixed) by a fixing method such as thermocompression bonding and sewing. In this case, the threadlike adhesive body easily and temporarily fixes the two articles with avoiding a fixing unit provided between the two articles. For example, in a case where a fiber product or a leather product is sewn, when temporary fixing is performed using the threadlike adhesive body, the temporary fixing can be easily performed while avoiding a part to be sewed, and the adhesive can be easily prevented from adhering to a needle. 
     In addition, the threadlike adhesive body can be well stuck while preventing a protrusion, a wrinkle, and overlapping even when shapes of two articles are a complicated shape such as a curved line, a curved surface, and an uneven shape. Further, the threadlike adhesive body can be stuck in one step, and workability is improved. 
     Even in a case of a member that is likely to be deformed, such as fabric, cloth, and leather that forms a fiber product or a leather product, temporary fixing can be performed using the threadlike adhesive body, so that deformation of the member due to tension can be inhibited, and a design after fixing (final fixing) is improved. 
     Further, in the case of using the threadlike adhesive body, after two articles are fixed (finally fixed), the threadlike adhesive body can be pulled out and removed if necessary from the two articles that are fixed (finally fixed). In this case, the adhesive can be prevented from squeezing out, and deterioration of a design due to aging discoloration of the remaining adhesive can be satisfactorily prevented. 
     Furthermore, the threadlike adhesive body can be twisted with a yarn made of other material to form a composite yarn or can be woven with a yarn or cloth (including nonwoven fabric and sheet) made of other material, thereby function combination can be attempted. 
     Further, the threadlike adhesive  2  stuck to the release liner (temporary support) can be transferred to the adherend by the threadlike adhesive sticking apparatus and the method of sticking threadlike adhesive of the present embodiment. The method will be described below. 
     First, the threadlike adhesive  2  is stuck to a temporary support in the form of a film or the like by the threadlike adhesive sticking apparatus and the method of sticking a threadlike adhesive of the present embodiment described above. In order to stuck the threadlike adhesive  2  to the adherend in a desired shape, the threadlike adhesive  2  is stuck (drawn) on the temporary support in a shape obtained by inverting the desired shape. 
     Next, the adhesive surface of the threadlike adhesive  2  stuck to the temporary support is brought into contact with the adherend, and the threadlike adhesive  2  is pressed and bonded to the adherend through the temporary support by a roller, a finger, or the like. 
     Thereafter, the temporary support is released and removed from the threadlike adhesive  2  adhered to the adherend to expose the threadlike adhesive  2 . In this way, the threadlike adhesive  2  is stuck to the adherend in a desired shape. 
     In order to reliably transfer the threadlike adhesive, that is, in order to prevent the threadlike adhesive from being peeled off from the adherend and remaining on the temporary support, it is preferable to peel off the temporary support from the adherend by peeling, and a peeling angle at this time is preferably 5° or more, more preferably 10° or more, and still more preferably 20° or more. When peeling the temporary support by peeling, the temporary support may be peeled off while being deformed, the adherend may be peeled off while being deformed, or both the temporary support and the adherend may be peeled off while being deformed. A suitable peeling method may be appropriately selected according to the hardness (deformability) of the temporary support and the adherend. 
     As described above, the threadlike adhesive  2  is formed (drawn) on the temporary support into a shape obtained by inverting a desired shape and then transferred to stick the threadlike adhesive  2  to the adherend in a desired shape. Accordingly, the threadlike adhesive  2  can be easily stuck to the adherend even when the sticking shape is complicated. 
     Based on such a feature, the method of sticking the threadlike adhesive by transfer is suitable as, for example, a method of sticking the threadlike adhesive body for fixing a cable such as an electric wire or an optical fiber, a LED fiber light, optical fiber sensors such as fiber Bragg gratings (FBG), various wires (linear members) such as a yarn, a string, or a wire, or a narrow member in a desired form. Even in the case of fixing a wire or a narrow member to another member having a complicated shape, with the method of sticking the threadlike adhesive by transfer, the threadlike adhesive can be easily stuck to a member to which a wire or a narrow member is stuck according to a complicated shape of the wire or the narrow member. 
     For example, in a case where the threadlike adhesive is used for temporary fixing when sewing fiber products or leather products such as clothes, shoes, bags, or hats, it is easy to temporarily fix the threadlike adhesive while avoiding a part to be sewed, and it is possible to easily prevent the adhesive from adhering to the needle. When an article to be sewn has a complicated shape or is easily deformed, it may not be easy to stick the threadlike adhesive. However, even in such a case, the threadlike adhesive can be easily stuck by the method of sticking the threadlike adhesive by transfer. 
     The present invention is not limited to the above embodiment, and modifications, improvements, and the like can be made as appropriate. Materials, shapes, sizes, numerical values, forms, numbers, arrangement positions, and the like of components in the embodiments described above are set as desired and are not limited as long as the present invention can be achieved. 
     EXAMPLE 
     Hereinafter, the present invention will be described in more detail with reference to Examples and the like, but the present invention is not limited to the following Examples. 
     Example 
     Preparation of Coating Solution 
     Into a reaction vessel equipped with a cooling tube, a nitrogen introduction tube, a thermometer, and a stirrer, 40 parts by mass of ion-exchanged water was added, and stirring was performed at 60° C. for 1 hour or more while introducing nitrogen gas to carry out nitrogen substitution. To this reaction vessel, 0.1 parts by mass of 2,2′-azobis[N-(2-carboxyethyl)-2-methylpropionamidine] n hydrate (polymerization initiator) was added. While the system was maintained at 60° C., a monomer emulsion A was gradually added dropwise thereto over 4 hours to allow an emulsion polymerization reaction to proceed. 
     As the monomer emulsion A, used as an emulsion obtained by adding and emulsified 98 parts by mass of 2-ethylhexyl acrylate, 1.25 parts by mass of acrylic acid, 0.75 parts by mass of methacrylic acid, 0.05 parts by mass of lauryl mercaptan (chain transfer agent), 0.02 parts by mass of y-methacryloxypropyltrimethoxysilane (manufactured by Shin-Etsu Chemical Co., Ltd., trade name: “KBM-503”), and 2 parts by mass of sodium polyoxyethylene lauryl sulfate (emulsifier) to 30 parts by mass of ion-exchanged water. 
     After completion of the dropwise addition of the monomer emulsion A, the system was further kept at 60° C. for 3 hours and cooled to room temperature, and pH was then adjusted to 7 by addition of 10% ammonia water to obtain an acrylic polymer emulsion (water-dispersible acrylic polymer). 
     A tackifying resin emulsion (manufactured by Arakawa Chemical Industries, Ltd., trade name: “E-865NT”) was added in an amount of 24 parts by mass based on the solid content per 100 parts by mass of the acrylic polymer contained in the above acrylic polymer emulsion. Further, ion exchange water was added to adjust the solid content concentration to 50 mass%, thereby obtaining a coating solution. 
     Production of Threadlike Adhesive 
     As a core material, a multifilament yarn was prepared by twisting seven polyester fibers having the number of filaments of  336  and a fineness of 1155 dtex 70 times/m. 
     The core material was coated by dipping the coating solution, in which a viscosity of the coating solution under the condition of a shear rate of 100 (1/s) was 0.4 Pa·s, and a viscosity of the coating solution under the condition of a shear rate of 0.1 (1/s) was 47 Pa·s, using a coating roller being rotated at the same speed as the feeding speed. At this time, a tension of 1.3 mN/dtex was applied to the core material. Thereafter, the resultant was dried at 100° C. for 4 minutes to obtain a threadlike adhesive body having a diameter (width in a lateral direction) of 0.45 mm. 
      Viscosity of Coating Solution 
     A viscosity of the coating solution was measured when the shear rate was changed from high speed (viscosity decrease) to low speed (viscosity recovery). 
     Specifically, 1 g of a sample (coating solution) was placed in a measurement plate (MP35 Steel, 18/8, sensor: Rotor C35/1, Cone with D = 35 mm, 1 ° Titan, gap between plates: 0.225 mm), and the solution viscosity (Pa·s) of the coating liquid was first measured at a shear rate of 0.01 (1/s) for 10 seconds under a condition of 23° C. using a viscosity-viscoelasticity measuring device (rheometer, trade name “RS-600”, manufactured by HAAKE). Thereafter, the shear rate was changed to 9000 (1/s) (A) over 20 seconds, and then, the shear rate returned to 0.01 (1/s) (B) over 20 seconds, and the solution viscosity (Pa·s) of the coating solution during this period was measured. 
     A value of the solution viscosity (Pa·s) of the coating solution at a time point when a shear rate was 100 (1/s) during the period in which the above shear rate was changed to 9000 (1/s) (A) was the solution viscosity (Pa·s) at a shear rate of 100 (1/s). A value of the solution viscosity (Pa·s) of the coating solution at a time point when a shear rate was 0.1 (1/s) during the period in which the shear rate returned to 0.01 (1/s) (B) was the solution viscosity (Pa·s) at a shear rate of 0.1 (1/s). 
     Tension of Core Material 
     The tension of the core material was measured using a digital force gauge (AD-4932A) during coating. Specifically, the tension between a feeding point of the core material and a coating roll was measured by reading the stress applied to a terminal of the force gauge. 
     Evaluation Results When Nozzle Hole Diameter Is Changed 
     Using the threadlike adhesive having a diameter of 0.45 mm produced as described above, a linear shape/curved shape (R = 10 mm, 5 mm, 2 mm, 1 mm) was drawn by changing the sticking speed of the threadlike adhesive to 1, 10, 20, 50, 100, 150, 200 mm/sec when the nozzle hole diameter was set to 1 mm and 2 mm. The experimental results are as follows. 
     In the case of a nozzle hole diameter of 1 mm, when drawing a linear shape, the threadlike adhesive was accurately stuck at each sticking speed excluding 200 mm/sec. In the case of drawing a curved shape, the threadlike adhesive was stuck at a sticking speed of 20 mm/sec or less (10 mm/sec or less in the case of R = 1 mm). 
     In the case of a nozzle hole diameter of 2 mm, when drawing a linear shape, the threadlike adhesive was accurately stuck at each sticking speed of 20 mm/sec or less. When drawing a curved shape, the threadlike adhesive was stuck at a sticking speed of less than 10 mm/sec in the case of R = 10 mm.
