The bead at the end of the bead string is bent and separated at the connecting section (15, 18) a needle (27) passes through axial bore of the bead (14, 16, 19) so that the bead is separated from the bead string and sewed onto the cloth (26).

Description: A METHOD AND APPARATUS FOR EMBROIDERING BEADS BACKGROUND OF THE INVENTION The present invention relates to an automatic bead embroidering method which makes it possible to sew beads to a cloth by the use of an embroidering apparatus that is used for embroidery on cloth, and to an apparatus which is used together with the embroidering apparatus in order to perform the method. Conventionally, decorative beads are made from materials such as glass, ceramics, metals, and plastics. Such beads are embroidered on cloth, as ornamentation for clothing. In such an embroidery, the beads are sewn to the cloth one by one using hand embroidering needles. Meanwhile, in regard to clothing ornamentation other than beads, a method in which flat plate-form ornaments are sewn onto cloth is disclosed in Japanese Patent Application Publication No. 45-16985 (U.S. Patent No. 3,390,650). In this method, flat plate-form ornaments are sewn onto the cloth, and the disclosure does not address cylindrical objects such as beads cannot be embroidered. Furthermore, multi-head type embroidering machines which perform embroidery by causing needles to perform a reciprocating motion perpendicular to a cloth, and shuttle type embroidering machines with a size of 15 yards or greater (formed by scaling up the multi-head type embroidering machines) have been in a practical use and are thus well known (U.S. Patent Nos. 2,030,495 and 3,062,163). In the case of bead embroidering methods using conventional hand sewing techniques, considerable time and labor are required. Thus, the productivity of such a method is extremely low. This delays the finishing of bead-embroidered products such as clothing, so that there are problems in terms of late delivery dates. Such late delivery dates are an extremely serious problem in the clothing industry, which is subject to abrupt changes in fashion. Furthermore, in the case of bead embroidering methods using hand sewing techniques, the quality and pattern of the embroidery are not uniform, and the reliability of the sewn attachments is poor. Embroidering threads on which beads are sewn may become slack, or may break so that multiple numbers of beads are lost. As a result, there are problems in terms of product quality. Furthermore, since the conventional embroidering machines perform embroidery using embroidering threads with attached beads, the bead embroidering process itself cannot be automated. SUMMARY OF THE INVENTION In light of the prior art described above, the present invention provides a method and apparatus for embroidering beads which makes it possible to automate the embroidering of beads on a cloth by linking a conventional embroidering apparatus to a bead embroidering mechanism. The present invention employs a method for embroidering beads wherein needles which perform a reciprocating motion relative to the surface of a cloth are used to affix a bead severed from a continuous bead string to the cloth. The beads are provided to in a continuous bead string by connecting multiple numbers of beads via easily separable connecting sections. The respective individual beads of each of the continuous bead string include an axial bore therethrough, and the connecting sections are formed to arrange the beads in a virtually linear arrangement along the direction of the axial bore of the beads.

DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows a flow chart of the method of the present invention. First, in Step 1, continuous bead strings used in the present invention are prepared. Examples of the continuous bead strings used in the bead embroidering method of the present invention are shown in Figures 2(a), 2(b) and 2(c), Cylindrical beads are depicted as examples. A top view, longitudinal section, and front view of each of the examples shown in Figure 2(a) , 2(b) and 2(c) is shown in Figures 3, 4 and 5(a), 5(b) and 5(c), respectively. Moreover, in regard to the bead shape, the present invention is not limited to the cylindrical shapes shown in the drawings it being understood that the invention is also applicable to other bead shapes which include an axial bore including; beads with circular and angular cross sections including: (hexagonal, square and other polygonal shapes) . In the example shown in Figure 2(a), a multiple number of glass beads 14 which have been cut beforehand into separate cylinders are bonded in a continuous line to a slender transparent tape 15, e.g., consisting of an acetate film with a width of 1 mm, by means of an adhesive. The respective beads are connected to each other via the tape 15. This tape 15 has an adhesive strength which allows for easy separation during the bead embroidering operation . In the example shown in Figure 2(b) , individual beads 16 are formed by way of cut-outs 17 (e.g., at 4-millimeter intervals) in a slender tube (consisting of plastic, etc.) with an external diameter of 2.5 to 3 mm and an internal diameter of 1.5 to 2 mm. These cut-outs 17 are formed in a cross-sectional direction by means of a cutter, with a portion of the tube left in each cut-out as a connecting section 18. Like the tape 15, these connecting sections 18 have a connecting strength that allows for easy separation during the bead embroidering operation. In the example shown in Figure 2(c), a belt is formed into a tube by bending, and individual beads 19 are formed by forming cut-outs 17 in the tube with connecting sections 18 left intact as in the same manner as in the example illustrated in Figure 2(b) . These connecting sections 18 have a strength which allows for easy separation during the bead embroidering operation. Figure 6 shows one example of a method which can be used to manufacture a continuous bead string of the type shown in Figure 2(c). A tape 20, for example a polyester film, which can withstand relatively high temperatures but also possesses thermoplasticity, is fed out from a roll and is formed into a long, slender tube with an external diameter of approximately 2.5 mm and an internal diameter of approximately 2 mm by means of forming rollers 21. This shape is fixed by means of a heater 22. The cut-outs 17 are formed in this tube material by means of a cutter 23. As a result, a continuous bead string 25 is formed, and this continuous bead string 25 is taken up on a reel 24. In cases where a bead string is manufactured by the forming and working of such a plastic film, various types of printing (using heat transfer printing, etc.) and finishing (using vacuum evaporation of aluminum, etc.) may be performed on the film before it is formed into a tube. Furthermore, various types of films can be manufactured relatively easily by lamination, and bead strings of various colors can be manufactured using these films. The connecting sections 18 of the bead strings are formed in a generally linear arrangement aligned with the direction of the axis of the axial bore of each bead. The reason for this is that it is necessary to bend each bead in a fixed direction, as will be described below. Accordingly, as long as each bead can be sent in a substantially fixed direction, it is not strictly necessary for the connecting sections 18 to be located on a straight line. Returning to Figure 1, in Step 2, the continuous bead strings are set in an embroidering apparatus which is itself a universally known type of apparatus. In this case, as will be described in concrete terms below, the bead embroidering mechanism or apparatus of the present invention is mounted beforehand on a universally known embroidering apparatus, and the continuous bead strings are set as described below in the bead embroidering apparatus of the present invention. Figure 7(a) illustrates one of the continuous bead strings 25 in its set state. Each bead string 25 is preferably set so that its connecting sections 18 face toward the cloth 26 that is to be embroidered. Each needle 27 in the embroidering apparatus performs a reciprocating motion, together with a corresponding shoulder or pushing part 28 which will be described later, in a direction preferably perpendicular to the cloth 26. In Step 3, when the setting of the continuous bead strings is completed, the embroidering apparatus is driven so that the embroidering operation is initiated. Each needle 27 performs a reciprocating motion as indicated by arrow A in Figure 7(a) , so that an embroidering thread 29 is stitched to the cloth 26. The cloth 26 is moved in accordance with the direction of embroidering, as shown by arrow B, relative to the reciprocating path 90 of each needle 27. Here, assuming that the embroidering thread 29 of each needle 27 is a surface-thread with respect to the cloth 26, the back thread on the opposite side of the cloth 26 is not shown in the drawings. Next, in Step 4, bead embroidering is started in accordance with a command to initiate bead stitching. As a result in, in Step 5, a linking means which links the bead embroidering mechanism with the driving mechanism or mechanisms of the needles 27 is actuated so that beads are embroidered by the action of the needles 27 as will be described later. First, in Step 6 and in accordance with the withdrawing action of each needle 27, indicated by arrow C in Figure 7(b), tip bead 25a of each bead string 25 is bent as indicated by arrow D. In this case, the tip bead 25a is bent about the corresponding connecting section 18 so that the bead 25a is oriented perpendicular to the cloth 26. This is done in order to open the rear end of the bead so that the needle 27 can be inserted into the axial bore of bead. Accordingly, as long as an opening which is sufficient to guide the needle 27 into the bead is formed, it is not absolutely necessary that the bead be bent into a perpendicular position. In linkage with the withdrawing motion of each needle 27, in Step 7, each bead string 25 is fed by one pitch (the length of one bead) toward the reciprocating path 90 of the corresponding needle 27 as shown by arrow E in Figure 7(c) . As a result, the tip bead 25a of each bead string 25 is positioned in the reciprocating path 90 of the corresponding needle 27. The bending action of Step 6 and the feeding action of Step 7 are both performed in linkage with the withdrawing motion of each needle 27, as will be described later; however, the order of these actions may be reversed. Next, in Step 8, each needle 27 advances as indicated by arrow F in Figure 7(d) and enters the corresponding tip bead 25a. Furthermore, in Step 9, as each needle 27 advances, the corresponding tip bead 25a is separated from the continuous bead string 25 by the corresponding pushing part 28 as shown in Figure 7(e) . Next, in Step 10, the needle 27 withdraws, and the tip end of the tip bead 25a is stitched to the cloth 26 as shown in Figure 7(f) . Next, in Step 11, the cloth 26 is moved in the direction indicated by arrow G in Figure 7(g), i.e., in such a direction that the needle 27 is caused to return to a previous position. As a result, the bead 25a is caused to fall over by the thread 29 as shown in Figure 7(g). With the bead 25a fallen over, in Step 12, the needle 27 makes one reciprocating motion as shown in Figure 7(h), sewing the tail end of the bead 25a. In Step 13, sewing action on one bead is thus finished. Next, a concrete embodiment of the bead embroidering apparatus which is mounted on the universally known embroidering apparatus in order to perform the bead embroidering operation will be described with reference to the subsequent figures. Figure 8 illustrates the structure of one embodiment of the bead embroidering apparatus of the present invention. A universally known shuttle type embroidering apparatus is equipped with a needle bar 30. A multiple number of needles 27 are fastened together with corresponding pushing parts 28 to the needle bar 30 at prescribed intervals via bolts 69. Bead embroidering mechanisms 33 constructed according to the present invention are installed at positions corresponding to the needles 27. These bead embroidering mechanisms 33 are fastened to the static part (not shown in the figures) of the embroidering apparatus via the fastening member 57 of the brackets 32 that are installed at prescribed intervals on a plate 31. Guide pipes 44 which guide bead strings 25 to the respective needles 27 are fastened to the plate 31. Three shafts, i.e., first, second and third shafts 34, 35 and 40, are mounted to the brackets 32. Hexagonal rollers 36 are rotatabl mounted on the first shaft 34. The bead strings 25 are carried around these hexagonal rollers 36 so that the cut-outs 17 (see Figure 2) are opened up. Bead-feeding sprocket wheels 37 are mounted on a second shaft 35. This shaft 35 is connected to an air cylinder 39 via a ratchet 38, so that the shaft 35 is intermittently driven by a prescribed pitch in one direction. Levers 42 are connected to the third shaft 40 via links 41. These levers 42 are installed so that they can rotate about supporting points 91 which are fastened to the plate 31. Furthermore, a pin 43 is installed at the tip end of each lever 42. The shaft 40 is connected to an air cylinder 45, so that the shaft 40 is caused to perform a reciprocating rotary motion. Reference numeral 51 is a jacquard punch tape used in the embroidering apparatus. The horizontal and vertical movements, i.e., movements in the X and Y directions, of the cloth frame (not shown) , on which the cloth that is to be embroidered is installed, are controlled by the hole program data of the tape 51, so that a desired embroidery pattern is automatically stitched. A bead embroidering ■■ start*' command is programmed, by punching, into this punch tape 51. The reciprocating motion, indicated by arrow A, of the needle bar 30 on which the needles 27 are installed is controlled by a cam 46. Timing projections 47 and 48 are formed on this cam 46, and switches 49 and 50 are provided so as to face the projections. As a result of this construction, the respective switches 49 and 50 are actuated for desired time periods by the timing of the reciprocating motion of the needles 27. The bead embroidering •■ start" command punched into the punch tape 51 is detected by a switch 52. When this command is detected, the outputs of the switches 49 and 50 are sent to the driving circuits 55 and 56 of the air cylinders 39 and 45 via AND circuits 53 and 54. As a result, the respective shaft 35 and 40 of the bead embroidering mechanisms 33 are rotated in linkage with the needles 27. The operation of the embodiment described above is illustrated in sequence in Figures 9 through 13. Figure 9 shows the state in which the bead strings 25 are set prior to the initiation of the bead embroidering operation. Each 5 bead string 25 is carried around one of the hexagonal rollers 36 so that the spaces between the beads are enlarged. The respective pins of the adjacent sprocket wheel 37 come into the respective space 92. Each bead string 25 is then guided into the corresponding guide pipe 10 44 with the connecting sections 18 of the bead string 25 facing toward the cloth 26. Thus, the cloth 26 is ready to be embroidered by the reciprocating action of the needle bar 30. When the bead embroidering "start" command of the 15 punch tape 51 is detected, the shaft 35 rotates by one pitch as shown in Figure 10. As a result, the sprocket wheel 37 is caused to rotate, so that each bead string 25 is fed out by one pitch. Accordingly, the tip bead 25a of the bead string 25 protrudes from the tip of the guide pipe 20 44 and moves into the reciprocating path 90 of the corresponding needle 27. Next, as shown in Figure 11, the shaft 40 is driven so that the lever 42 is rotated via the link 41 in the direction indicated by arrow H. As a result, the tip-end 25 pin 43 on the lever 42 presses against the tip bead 25a, and bends the bead 25a as indicated by arrow D. Next, as shown in Figure 12, the needle 27 advances and enters the tip bead 25a. At the same time, the lever 42 rotate in a reverse direction so that the pin 43 moves 0 away from the guide pipe 44. Furthermore, by the advancing motion of the needle bar 30 as shown by arrow F, the pushing part 28 comes into contact with the tip bead 25a and separates the tip bead 25a from the bead string 25 as shown in Figure 13. 5 Subsequent operations are performed as illustrated in Figures 7(f) through 7(h) . Front, top and side views of a second embodiment of -li¬ the bead embroidering apparatus of the present invention are shown in Figures 14, 15 and 16, respectively. Like the previous embodiment described above, this second embodiment is mounted on a known bead embroidering apparatus. In this embodiment, as shown in Figure 22, the fastening part 57 of the bracket 32 is fastened to a drill base 80 which is used to open embroidering holes in the cloth. A shaft 60 is rotatably mounted onto the bracket 32 via bearings 64. A shaft 61 is also mounted to the bracket 32, and the bead string 25 is wound around hexagonal rollers 61a which are mounted on this shaft 61. A plate 31 is fastened to the brackets 32. Grooves are formed in this plate 31 at intervals corresponding to the spacing of the needles, and guide pipes 44 are spot-welded in these grooves as shown in Figure 17. Bead string guide pipes 65 are inserted into the guide pipes 44 with sleeve bearings 85 interposed so that the bead string guide pipes 65 are free to slide. The bead strings 25 are inserted into these bead string guide pipes 65. Figure 18 is a front view of the needle bar 30. The needle 27 and pushing part 28 are fastened to the needle bar 30 by a bolt. As illustrated in Figure 14, collars 62 are fastened to the shaft 60, and a lever 42 is connected to each of these collars 62 via a link 41. Two pins 66 and 67 are mounted on each lever 42 as shown in Figure 16. The respective pins 66 and 67 engage with both ends of a pipe 68 which is fastened to each of the bead string guide pipes 65. As shown in Figures 19 and 20, an air cylinder 71 is installed for each predetermined number of bead embroidering mechanisms 33. The piston rod 72 of each of these air cylinders 71 is connected to a link lever 73 via a shaft 74. This link lever 73 is fastened to the shaft 60. As a result, when the piston rod 72 of each air cylinder 71 performs a reciprocating motion as indicated by arrow I, the shaft 60 is caused to perform reciprocating rotary motion, as indicated by arrow J, via the corresponding link lever 73. Figure 21 illustrates the structure of the electrical control system of the embodiment. A shaft 75 is used to drive the needle bar 30. The needle bar 30 performs a reciprocating motion in accordance with the shape of a cam 46 which is fastened to the shaft 75. A switch cam 76 is also fastened to the shaft 75, and a switch 77 is also installed so as to be actuated by this switch cam 76. When bead stitching positions are reached during the embroidery process using an embroidering thread, the switch 52 detects a bead embroidering "start" command via pins 95 in accordance with program data which is formed in the punch tape 51 beforehand. Here, when the switch 77 is actuated, a relay 96 is actuated so that the contact S and RS 12 are actuated. These act together with the previously actuated switch 52 so that a further relay 98 is actuated. As a result, the contacts RS 31 and RS 32 of the relay 98 are actuated. The contact RS 31 maintains the relay 98 in the actuated state and also actuates an air valve 79 via a solenoid 78. As a result, the air cylinder 71 is driven so that the shaft 60 is caused to rotate. When the shaft 75 enters its second revolution, the switch 52 has already been returned. When the switch 77 is again actuated by the cam 76, the relay 96 is actuated. Accordingly, the contacts RS n and RS 12 of the relay 96 are actuated so that the relay 97 is actuated. As a result of the actuation of this relay 97, the contact RS 21 of the relay 97 is actuated so that the self-maintenance of the relay 98 is released and relay 98 is no longer actuated. The contacts RS 31 and RS 32 of the relay 98 then return to their original positions, so that the air valve 79 is reset. As a result, the air cylinder 71 performs a reverse driving action so that the shaft 60 is caused to rotate in reverse. The operation of the above-described embodiment is illustrated in sequence in Figures 22 through 27. The operation is substantially the same as that shown in Figure 7 which is described based upon the flow chart of Figure 1. Figure 22 shows the state in which the bead string 25 is set. As described above, the bead strings 25 are loaded in the bead string guide pipes 65 with their connecting sections facing the cloth 26. The tip end bead 25a of each bead string 25 protrudes from the tip of the corresponding bead string guide pipe 65. In accordance with the bead embroidering "start" command, the shaft 60 is driven as indicated by arrow K, as shown in Figure 23, in linkage with the withdrawing motion of the needle bar 30, so that the link 41 is pushed in the direction indicated by arrow L, thus causing the lever 42 to rotate in the direction indicated by arrow M. As a result, the pin 43 on the tip of the lever 42 bends the corresponding tip bead 25a toward the cloth. At this time, the pin 67 on the lever 42 contacts the pipe 68 provided on the corresponding bead string guide pipe 65, thus stopping the rotation of the lever 42. Afterward, when the collar 62 rotate further during the withdrawing action of the needle bar 30, the lever 42 moves together with the pipe 68 in a direction parallel to the movement of the link 41 as indicated by the arrow P in Figure 24, since the lever 42 cannot rotate. Furthermore, the levers 42 are connected to the pipes 68 via supporting points 100 so that the levers 42 are free to rotate. As a result, the bead string guide pipes 65 slide through the guide pipes 44 toward the needles, so that the tip bead 25a of each bead string 25 is positioned in the reciprocating path of the corresponding needle 27. As a result of this action, each bead string 25 is fed by one pitch in the direction indicated by arrow N. Next, as shown in Figure 25, the needle 27 advances and enters the tip beads 25a, and the pushing part 28 contacts the tip end bead 25a so that the bead 25a is separated from the bead string 25. Next, as shown in Figure 26, the shaft 60 is caused to rotate reversely, as indicated by arrow Q, together with the withdrawing motion of the needles 27. Accordingly, the link 41 is drawn in the direction indicated by arrow R, so that the lever 42 is caused to rotate in the direction indicated by arrow S. As a result, the pin 43 at the tip of the lever 42 is caused to move away from the tip of the bead string guide pipe 65. Then, when the pin 69 on the lever 42 contacts the pipe 68 which is fastened to the corresponding bead string guide pipe 65, the rotation of the levers 42 is stopped. When the shaft 60 rotates even further, the bead string guide pipes 65 are drawn upward in the direction indicated by arrow T in Figure 27 via the pipe 68 together with the motion of the link 41, since the lever 42 cannot rotate. As a result, the next bead 25b of the bead string 25 becomes the tip bead and is caused to protrude from the tip of the corresponding bead string guide pipe 65. Together with this operation, the bead stitching operation is performed as illustrated in Figure 7. Figure 28 illustrates third embodiment of the present invention. This embodiment illustrates a case in which bead embroidering mechanism or mechanisms 33 constructed according to the present invention are attached to a single-head type or multi-head type embroidering apparatus 81 which performs embroidery on a horizontally positioned cloth 26. By changing the shape of mounts of the brackets, it is possible to mount bead embroidering mechanisms of the present invention onto embroidering machines of various shapes and dimensions. According to the present invention, as described above, cylindrical beads or angular tube shaped beads are automatically stitched at predetermined positions during an embroidering process utilizing an ordinary embroidering thread. Furthermore, bead embroidering mechanisms constructed according to the present invention can easily be attached to existing embroidering machines, thus making it possible to utilize the embroidering machines effectively and to improve the functioning of the machines. The use of the bead embroidering method and apparatus of the present invention makes it possible to manufacture desired stable bead embroidery patterns with high reliability compared to methods using conventional hand sewing techniques. Accordingly, the quality and the productivity can be greatly improved while lowering the cost. Furthermore, along with the improvement in quality and increase in productivity, there is a reduction in the time required for manufacturing. Accordingly, product delivery times can be stabilized and shortened even in areas remote from the manufacturing site. As a result, clothing fashions, which are subject to abrupt changes, can be dealt with timely.

AMENDED CLAIMS [received by the International Bureau on 17 February 1992(17.02.92); original claims 1, 2 and 5 amended; other claims unchange (2 pages)] CLAIMS: 1. A method for embroidering beads (14) onto a cloth (26) comprising: providing an embroidering apparatus equipped with 5 at least one thread carrying needle (27) which performs a reciprocating motion relative to the surface of a cloth (26) to attach a thread stitch to said cloth (26) ; providing at least one continuous bead string having multiple numbers of beads (14,16) each having 10 aligned axial bores therethrough, said beads (14,16) of said continuous bead string interconnected via separable connecting sections; installing said continuous bead strings in said embroidering apparatus in an arrangement conducive to the 15 respective sewing of said beads (14,16) to the surface of said cloth (26) ; repetitively engaging a tip bead (14,16) of said continuous bead string with said thread carrying needle (27) ; 20 severing said connecting section (15, 18) between said needle engaged tip bead (14, 16) and said continuous bead string; and affixing said severed tip bead (14,16) to said cloth (26) . 25 2. The method according to Claim 1, wherein said engaging, severing and affixing steps of said method further comprise: bending a tip bead (14,16) of said continuous 30 bead string about said connecting section (15,18); feeding the continuous bead string such that, following said bending and feeding steps, said axial bore of said tip bead (14, 16) of said continuous bead string is positioned in the path of reciprocating motion of said at 35 least one needle (27) ; inserting said needle (26) into and through the axial bore of said tip bead (14,16); forcibly advancing said tip bead (14,16) toward said cloth (26) to cause said connecting section (15,18) to break; affixing a thread proximate a tip end of said tip bead (14,16) to said cloth (26); withdrawing said needle (27) from said bead (14,16); shifting said cloth (26) with respect to said needle (27) so that said separated bead orients properly on said cloth (26) surface; and sewing said thread proximate a tail end of said tip bead (14,16) to said cloth (26) after said tip bead (14,16) has oriented onto the cloth surface. 3. The method for embroidering beads (14) according to Claims 1 or 2, wherein the continuous bead strings are initially formed by bonding beads to a belt-form material (15). 4. The method for embroidering beads (16) according to Claims 1 or 2, wherein said at least one continuous bead string is formed by forming cross-sectional cut-outs (17) in a tube-form material with a portion of the tube-form material left intact as a connecting section (18) between successive beads (16) . 5. The method for embroidering beads according to Claims 1 or 2, wherein the method further includes forming said at least one continuous bead string by the steps of: bending a long belt-form material (20) to form a tube-form material; and forming cross-sectional cut-outs (23) in said tube-form material to define individual beads (19,25) with a portion of the tube-form material left intact as a connecting section (18) between successive beads (19,25) . 6. An embroidering apparatus, of the type equipped STATEMENT UNDER ARTICLE19 The specification on page 1, line 18 has been amended as suggested by the Examiner. Additionally, Claim l, line 15, Claim 2, line 16, and Claim 5, line 4 have been amended as suggested. These changes are included in the attached substitute pages 1, 16 and 17. These changes do not change the scope or subject matter of the application. Applicant's invention details an apparatus and method of affixing beads from a continuous bead string, wherein the bead have aligned axial bores. to the surface of a cloth. By comparison, the two references which the Search Report indicated were of particular relevance to certain claims (U.S.A. 3,390,650 and U.S.A. 4,807,546) both address affixing disk shaped sequins to a cloth. It is particularly relevant that the sequins of the references have holes which are oriented perpendicular to the continuous sequin chain. Thus, these holes are not "aligned" as are the axial bores of the bead string of the present application. Further, there is no discussion of "bending the tip bead" (or sequins) about the connection section to align the axial bore with the needle. Thus, the two references do not anticipate the claims of the present invention. In view of the corrections and these comments, it is believed that all of the claims are directed to allowable subject matter.
