Description

Chain and zipper

The present invention relates to a chain belt and a zipper, and more particularly to a zipper-like chain belt and a zipper which are attached to a side of a cloth such as a garment and which are branched into two front and back sheets.

The zipper chain belt includes: a chain cloth extending in the longitudinal direction; and a chain longitudinally mounted on one end side of the chain cloth in the width direction (the direction perpendicular to the longitudinal direction and parallel to the front and back surfaces of the chain cloth) tooth. In the chain belt, a cloth such as clothes is attached to a portion on the opposite side of the fastener element in the width direction of the chain fabric by sewing or the like. In the U.S. Patent No. 2,368,911, a sheet-like chain tape in which the portion of the chain fabric in the width direction and the opposite side of the fastener element (the cloth mounting side) is branched into two sheets of the front and back is disclosed. This chain tape is attached to the fabric by an adhesive in a state in which the sheets of the front and back sheets are opposed to each other, and the film is interposed between the sheets of the front and back sides. Further, it is also possible to attach the cloth between the sheets which are branched into the front and back, and to mount them by sewing. Thereby, the fabric and the like of the clothes can be improved in body feeling.

Here, the chain fabric is formed by weaving the warp yarns in the longitudinal direction and the weft yarns in the width direction, and the weaving in the width direction is smaller than the narrow width in the longitudinal direction. As the woven structure, one weft yarn is shuttled in the width direction with respect to a plurality of warp yarns arranged in the width direction, and is folded back on one end side (sprocket mounting side) of the chain cloth, and a yarn loop is formed on the other end side. Fold back and repeat this operation for woven. Regarding the yarn loop, another yarn loop adjacent in the longitudinal direction is passed through a loop, and the loop is continuously chain-like in the longitudinal direction. Therefore, the other end side on which the yarn loop is formed is thickened to cause thickening, and if a usual chain cloth is used, in the above manner When the cloth is placed in a state where the cloth is interposed, the step between the chain of the back and the back of the two pieces is easily generated.

An object of the present invention is to provide a chain belt and a zipper which can reduce the step difference between the chain cloth and the cloth after the sheet-like portion of the fabric of the chain cloth is branched into a sheet-like portion of the front and back sheets and the cloth is sewn.

In order to solve the above problems, according to the present invention, a fastener tape comprising a chain cloth and a fastener element which is attached to one side in a width direction perpendicular to a longitudinal direction of the chain cloth and which is installed along the longitudinal direction is provided. And the chain cloth is disposed on the other side opposite to the one side in the width direction, and is branched into a branch portion of the front side sheet portion and the back side sheet portion, and the chain cloth is made of warp yarns along the length direction. The weft yarn is woven by the weft yarn in the width direction, and the weft yarn is folded back at the other end of the width direction of each of the front side sheet portion and the back side sheet portion, and the length is formed at the end of the one side in the width direction. Fold back in a chain of continuous loops.

In the present invention, the chain fabric is woven by a warp yarn in a longitudinal direction and a weft yarn in a width direction, and the weft yarn is folded back at the other end of the width direction of each of the front side sheet portion and the back side sheet portion. Further, a yarn loop continuous in the longitudinal direction is formed at the end of the one side in the width direction to be folded back. Therefore, the thickness of the front side of the other side of the chain cloth is formed to be thinner than the thickness of the front side of the one side of the chain cloth.

In one embodiment of the present invention, the weft yarn is integrally formed by two yarns on the one side in the width direction of the chain fabric, and the two yarn-like yarns are branched from the chain fabric. Each of the starting points is separated from the front side sheet portion toward the front side sheet portion. In this case, the two yarn-like yarns forming the weft yarn are divided into the front side sheet portion and the back side sheet portion in each of the branch portions, whereby the front side and the back side can be made smaller than the portions other than the branch portion of the chain cloth. The amount of the weft yarns in each of the side sheet portions is halved, so that the thickness of each of the front and back side sheet portions is made thin. Therefore, when the cloth is sewn between the front side and the back side sheet portion, the step difference between the front side and the back side sheet portion and the cloth is small. Further, since the portion other than the branch portion of the chain cloth (the element attaching portion) is thick, the mounting state of the fastener element is stabilized, and the mounting strength of the fastener element can be easily maintained.

According to another aspect of the present invention, there is provided a zipper comprising a left and right chain cloth; left and right sprocket teeth, which are attached to one side of a width direction perpendicular to a longitudinal direction of each chain cloth, are mounted along a length direction; and a slider And the chain cloth is opened and closed between the left and right fastener elements; and the chain cloth is included on the other side opposite to the one side in the width direction, and the two branches are branched into the front side sheet portion and the back side sheet portion. a branching portion, wherein the chain fabric is woven by a warp yarn in a longitudinal direction and a weft yarn in a width direction, and the weft yarn is folded back at an end of the other side in a width direction of each of the front side sheet portion and the back side sheet portion. And at the end of the one side of the width direction, a continuous loop of yarns in the longitudinal direction is formed and folded back. Such a zipper uses the above-described chain belt of the present invention.

In one embodiment of the present invention, the weft yarn is formed on the one side in the width direction of the chain fabric, and includes two yarn-like yarns integrally combined, and the two yarn-like yarns are each from a branch starting point of the chain fabric. One piece of the sheet is separated from the back side sheet portion toward the front side sheet portion. In this case, the two yarn-like yarns forming the weft yarn are divided into the front side sheet portion and the back side sheet portion in each of the branch portions, whereby the front side and the back side can be made smaller than the portions other than the branch portion of the chain cloth. The amount of the weft yarns in each of the side sheet portions is halved, so that the thickness of each of the front and back side sheet portions is made thin. Therefore, when the cloth is sewn between the front side and the back side sheet portion, the step difference between the front side and the back side sheet portion and the cloth is small.

In one embodiment of the present invention, the chain cloth includes a fastener element mounting portion to which the fastener element is attached, and the branching portion is from the end of the fastener element mounting portion toward the other side, starting from the branch point The front side sheet portion and the back side sheet portion are branched, and a stopper is attached to the element attaching portion side at the end portion in the longitudinal direction of the element row. The stop includes an upper stop, a lower stop, and a detachable insert.

In the present invention, the chain fabric is formed by woven a warp yarn in a longitudinal direction and a weft yarn in a width direction, and the weft yarn is attached to the end of the one side in the width direction to form a yarn continuous in the longitudinal direction. The loop is folded back, and the thickness of the front side of the other side of the chain cloth is formed to be thinner than the thickness of the front side of the side of the chain cloth. Thereby, after the sheet-like portion which is branched into the back of the fabric of the chain cloth is sewn into the sheet-like portion of the front and back sheets, the step difference between the chain cloth and the cloth can be reduced. Therefore, it is possible to further enhance the sense of the fabric such as clothes and the chain belt.

The preferred embodiments of the present invention are described below, but the present invention is not limited to the embodiments, and may be appropriately modified within the scope of the claims and the scope of the claims. Fig. 1 is a plan explanatory view showing a zipper 100 using a fastener tape 10 according to an embodiment of the present invention in a longitudinal direction (based on the upper and lower directions of the paper surface of Fig. 1). Figure 2 is a cross-sectional view taken along line A-A of Figure 1. The zipper 100 includes a pair of woven fabrics 11 on the left and right sides (left and right based on the paper sheets of Figs. 1 and 2); a pair of right and left sprocket teeth 20, which are oriented in the width direction of each of the chain fabrics 11 (vertical to the longitudinal direction) And on the opposite side end portions of the direction parallel to the front and back sides of the chain cloth 11 are mounted in the longitudinal direction; the metal sliding member 30 is used for engaging and disengaging the fastener elements 20; Or a resin upper stop 40 and a detachable insert 50 (stop), which are disposed at both ends of the longitudinal direction of the fastener element 20 in the longitudinal direction, and define the orientation length of the slider 30. The limit of moving one direction and the other. The sprocket 20 of the present embodiment is formed by bending a monofilament fiber made of a thermoplastic synthetic resin such as polyester or polyamide, into a loop shape or the like, and continuously including the meshing head 21, the upper leg 22, and the opposite. The rotating portion 23 and the lower leg portion 24. Moreover, the ring-shaped sprocket 20 may be attached to the reverse side of the chain fabric 11 (the side opposite to the mounting surface side in Fig. 1). Further, the direction perpendicular to the front and back surfaces of the fastener fabric 11 (front and back directions) is referred to as a thickness direction, and in the following description, the thickness means the dimension in the thickness direction.

The slider 30 includes a slider body 30a including an upper blade 31, a lower blade 32, and the like, a cover member 33 fixed to the upper blade 31, and a pull tab 34 rotatably coupled to the cover member 33. The slider main body 30a is moved to the upper side of the sheet of FIG. 1 (hereinafter referred to as "upper direction") by the user's holding tab 34, and the engaging heads 21 of the left and right fastener elements 20 are closed, and by sliding The main body 30a is moved to the lower side of the sheet of FIG. 1 (hereinafter referred to as "lower in the longitudinal direction"), and the engaging heads 21 are opened. The upper stopper (stop) 40 includes left and right upper stopper members 41 attached to the upper end in the longitudinal direction of the element rows of the fastener elements 20 on the left and right chain cloths 11. The detachable insert 50 includes: a pin 51 and a pin 53 attached to a lower end of the sprocket row of the sprocket 20 of the left and right chain cloths 11; and a tail cylinder 52 integrated with the pin 51 The other latch 53 can be inserted to engage. When the tail cylinder 52 is engaged with the above-described plug 53, the longitudinal end portions of the left and right chain belts 10 are coupled to each other. Then, the slider 30 is moved down to the detachable insert 50, and the latch 53 is pulled out from the tail cylinder 52 through the slider 30, whereby the left and right chain belts 10 are separated. The chain belt 10 is attached to the chain cloth 11 with a fastener element 20, an upper stop (stop) 40, and a detachable insert (stop) 50. Alternatively, a lower stop (stop) may be installed instead of the detachable insert 50. The zipper 100 includes engaging the respective sprocket teeth 20 of the left and right chain belts 10. Separate slider 30.

Referring to Fig. 2, each of the chain fabrics 11 is divided into a fastener attachment portion 12 on the side (one side or the opposite side) on which the fastener elements 20 are attached in the width direction, and the other side in the width direction (hereinafter referred to as "clothing". The two sides of the mounting side ") are branched into the branch portion 13 of the front and back. The element attaching portion 12 is included in the intermediate portion 14 of the sprocket mounting portion 12 that is out of the range of the sprocket 20. The branch portion 13 includes a front side sheet portion 13a and a back side sheet portion 13b which are divided into two from the branch start point 15 which is the boundary of the element attaching portion 12 (the intermediate portion 14) toward the cloth mounting side. The length of the back sheet portion 13b in the width direction, that is, the length from the branch start point 15 to the cloth attachment side end is longer than the length of the front side sheet portion 13a in the width direction by 0.3 mm to 3.0 mm. In other words, the other end of the back side sheet portion 13b (the end on the cloth mounting side) is offset in the width direction with respect to the other end of the front side sheet portion 13a (the end on the cloth mounting side), and the width direction thereof The difference in offset is 0.3 mm to 3.0 mm, which is fixed over the entire length direction. The difference can be set based on the thickness of the cloth or the like attached to the front side and the back side sheet portions 13a and 13b.

Here, in order to sandwich the cloth between the front side sheet portion 13a and the back side sheet portion 13b, the front side sheet portion 13a (or the back side sheet portion 13b) is folded by hand with respect to the back side sheet portion 13b (or the front side sheet portion 13a). In the case where the lengths of the front side and the back side sheet portions 13a and 13b in the width direction are equal, it is difficult to fold. However, as described above, the other end of the back side sheet portion 13b is offset in the width direction with respect to the other end of the front side sheet portion 13a, and therefore, it is easy to fold when the cloth is sandwiched. Further, in general, the sewing system operator performs the visual inspection on the front side of the fastener tape, so that the front side branch sheet is surely sewn to the front side. On the cloth, there is a case where the back side branch sheet portion cannot be successfully sewn to the cloth. Such a sewing error is particularly likely to occur in the case where the fabric is attached to the side end of the fabric in the width direction of the chain fabric, the back side branch sheet is bulged in the thickness direction of the cloth due to the thickness of the cloth, and the width of the back side branch sheet is woven. The position in the width direction of the mounting side end is shifted to the element side in the width direction of the cloth mounting side end in the width direction of the front side branching sheet, but the length in the width direction of the back side sheet portion 13b is longer than the front side sheet portion 13a. The length of the width direction makes the sewing error less likely to occur.

In this manner, the chain belt 1 described above is attached to the branch portion 13 of the chain fabric 11, and the other side of the front side sheet portion 13a in the width direction (the side opposite to the side on which the fastener elements are attached) and the back side sheet are provided. The other end of the portion 13b in the width direction is shifted in the width direction, whereby the length in the width direction of the front side sheet portion 13a and the back side sheet portion 13b, that is, in the width direction from the beginning toward the front and back sides The length at which the sheet portions 13a and 13b are branched into two places (the branch start point) 15 to the ends of the other side is different. Thereby, when the cloth is interposed between the front side sheet portion 13a and the back side sheet portion 13b, the front side sheet portion 13a (or the back side sheet portion 13b) is easily folded over the back side sheet portion 13b (or the front side sheet portion 13a). . Further, when the operator performs the sewing on the front side of the fastener tape 10, it is preferable that the length of the back side sheet portion 13b in the width direction is longer than the front side sheet portion 13a. When the cloth such as clothes or bags is inserted between the front side and the back side sheet portions 13a and 13b to be sewn, even if the back side sheet portion 13b is swollen in the thickness direction of the cloth (see FIGS. 4 and 5), the back side sheet can be prevented. The position in the width direction of the fabric-mounted side end of the width direction of the portion 13b is shifted to the side of the element 20 in the width direction of the cloth-mounted side end in the width direction of the front side sheet portion 13a. In the case where the operator performs the sewing while viewing the back side of the fastener tape, it is preferable that the length of the front side sheet portion in the width direction is longer than that of the back side sheet portion.

Fig. 3 is an explanatory view schematically showing a woven structure of the chain fabric 11. The chain fabric 11 is formed by weaving a warp yarn 11a (see Fig. 3) in the longitudinal direction and a weft yarn 11b in the width direction. In the present embodiment, the weft 11b is present in a plurality of warp yarns 11a arranged in the width direction. After the front side of one warp yarn 11a, it appears on the back side of the next warp yarn 11a (the warp yarn 11a adjacent to the one warp yarn 11a in the width direction), and the front and back are alternately woven in the width direction. In this manner, in the warp yarn 11a, the weft yarn 11b from the opposite side in the width direction toward the cloth mounting side with respect to the warp yarn 11a in the front and back alternating pattern (first pattern) does not form the following yarn loop (11c) at the cloth mounting side end. The direction is slightly staggered and faces the opposite side in the width direction. At this time, the front and back alternating pattern of the weft 11b with respect to the warp yarn 11a is opposite to the front first pattern. The weft yarn 11b is folded back after forming the yarn loop 11c at the opposite side end, and is slightly shifted in the longitudinal direction to face the fabric attachment side in the width direction. The other loop 11c adjacent in the longitudinal direction is passed through a loop 11c while the loop 11c is continuously chain-like in the longitudinal direction. Further, the weft yarn 11b is formed by integrally combining two yarn-like 11ba in the element attaching portion 12 of the chain cloth 11, and the two yarn-like 11ba are oriented one by one from the branch starting point 15 of the chain cloth 11 toward the front side sheet. The portion 13a is separated from the back side sheet portion 13b. Therefore, each of the front side sheet portion 13a and the back side sheet portion 13b of the weft yarn 11b includes one yarn shape 11ba, and the thickness of each of the front side sheet portion 13a and the back side sheet portion 13b becomes thinner than the thickness of the element attaching portion 12 ( Refer to Figure 2). Further, the thickness of the end where the yarn loop 11c is formed becomes thicker than the thickness of the fastener element mounting portion 12. The thickness of the chain fabric 11 can be measured by a dial thickness gauge (DIAL THICKNESS GAUGE). For example, when the chain fabric 11 is measured, the thickness of the portion of the yarn loop 11c formed at one end is 0.4 mm or more. The thickness of the front side sheet portion 13a or the back side sheet portion 13b at the end of the other side of 0.9 mm or less is 0.2 mm or more and less than 0.4 mm, respectively. The fastener element 20 is attached to the fastener element mounting portion 12 of the chain fabric 11 by the mounting yarn 11e. Further, reference numeral 11d in Fig. 2 is passed through the center line of the fastener element row of the fastener element 20.

FIG. 4 is a cross-sectional explanatory view showing a state in which the cloth 1 such as clothes is attached to the zipper 100. The cloth 1 is inserted between the front side sheet portion 13a and the back side sheet portion 13b of the branch portion 13 of each of the fastener tapes 10, but at this time, the end of the cloth-side mounting side of each of the front side sheet portion 13a and the back side sheet portion 13b is offset. Therefore, the front side sheet portion 13a can be easily folded over with respect to the back side sheet portion 13b. After the fabric 1 is interposed between the branch portions 13, the front side sheet portion 13a, the cloth 1 and the yarn 2 are separated by the yarn 2. The back side sheet portion 13b is sewn and thereby attached to the chain cloth 11. In this example, the opposite sides of the branch portion 13 and the two portions on the cloth mounting side are sewn in the entire longitudinal direction. In general, the sewing system is performed while visually observing the side of the front side sheet portion 13a of the fastener tape 10. According to FIG. 4, when the fabric 1 is interposed between the front side sheet portion 13a and the back side sheet portion 13b, the back side sheet portion 13b is bulged in the thickness direction of the cloth due to the thickness of the cloth 1, so that the back side sheet is swelled. The width-direction cloth mounting side end of the portion 13b is offset to the opposite side. However, since the back side sheet portion 13b has a length in the width direction longer than the front side sheet portion 13a, the cloth mounting side end of the back side sheet portion 13b which is bulged in the thickness direction of the cloth is still slightly smaller than the cloth mounting side end of the front side sheet portion 13a. Located on the fabric mounting side. Therefore, particularly in the sewing of the cloth mounting side of the branch portion 13, the back side sheet portion 13b which is invisible to the operator can be surely sewn. Further, since the front side sheet portion 13a and the back side sheet portion 13b are thinner than the element attaching portion 12 of the chain cloth 11, the step difference between the stitched front side and the back side sheet portions 13a and 13b and the cloth 1 is small. , the impression of a clear appearance.

FIG. 5 is a cross-sectional explanatory view showing a state in which the end portion of the cloth 1 is folded back and sewn to the branch portion 13 of the fastener tape 10. In this case, the thickness of the cloth 1 interposed between the front side sheet portion 13a and the back side sheet portion 13b is partially doubled, and accordingly, the back side sheet portion 13b is directed toward the back side (based on the lower side of the sheet of FIG. 5). It also becomes larger than that of FIG. 4, so that the offset toward the opposite side of the cloth-mounted side end of the back side sheet portion 13b also becomes larger than that of FIG. However, since the cloth attachment side end of the back side sheet portion 13b is located at substantially the same width direction as the cloth attachment side end of the front side sheet portion 13a, sewing error to the back side sheet portion 13b is hardly generated.

Fig. 6 shows a variation of the chain belt, and the configuration other than the chain cloth is the same as that described. The chain fabric 61 in the fastener tape 60 of Fig. 6 includes a front side chain portion 61a and a back side chain portion 61b. The front and rear side chain portions 61a and 61b are joined to each other by the element attaching portion 62, and the branch portion 63 is maintained in a state of being separated without being joined. That is, the other side is branched into two strands from the fastener element mounting portion 62 which is joined by the mounting yarn. The branch portion 63 includes a front side sheet portion 63a which is a portion of the front side chain portion 61a which is branched from the branch start point 65 toward the cloth mounting side, And a portion of the back side chain portion 61b, that is, the back side sheet portion 63b. The cloth attachment side end of the back sheet portion 63b is offset from the cloth attachment side end of the front side sheet portion 63a to the cloth attachment side, and the back side sheet portion 63b is longer than the front side sheet portion 63a in the width direction. In this example, the front side chain portion 63a and the back side chain portion 63b are woven, and the weft yarns on the cloth mounting side with respect to the warp yarn from the opposite side in the width direction are not formed with a loop at the cloth attachment side end. It is slightly staggered in the longitudinal direction and faces the opposite side in the width direction. At this time, the alternating pattern of the weft yarns with respect to the warp yarns is opposite to the front first pattern. The weft yarn is folded back after forming the yarn loop at the opposite side end, and is slightly shifted in the longitudinal direction to face the width direction cloth mounting side. Another yarn loop adjacent in the longitudinal direction is passed through a loop, while the loops are chain-likely continuous in the length direction. In the above description, the length of the back side sheet portion 63b in the width direction is longer than that of the front side sheet portion 63a. However, in the sewing operation, the back side sheet portion may be sewn while being viewed. In response to this, the length of the front side sheet portion in the width direction is longer than that of the back side sheet portion.

Fig. 7 is a partial plan explanatory view showing the zipper 101 of the chain belt 80 according to another embodiment of the present invention taken along a line. Fig. 8 is a cross-sectional explanatory view taken along line B-B of Fig. 7. The slide fastener 101 includes left and right chain cloths 81 and left and right fastener elements 90 attached to opposite end portions of the respective link fabrics 81 in the width direction. A slider or the like of the zipper 101 is omitted from illustration. The fastener element 90 is a resin manufacturer formed by injection molding a thermoplastic resin such as polyacetal, nylon or polypropylene onto the chain cloth 81. Each of the fastener fabrics 81 is divided into a fastener element mounting portion 82 to which the fastener element 90 is attached in the width direction, and a branch portion 83 which is branched into the front and back sides of the fabric attachment side. The branch portion 83 includes a front side sheet portion 83a and a back side sheet portion 83b that are divided into two from the branch starting point 85, which is the boundary with the element attaching portion 82, toward the cloth mounting side. The end of the front side sheet portion 83a on the cloth mounting side is formed in a shape in which the circular arc 83c is continuous in the longitudinal direction. The end of the front side sheet portion 83a on the cloth mounting side can be formed by cutting the end of the fabric mounting side of the front side sheet portion 83a by, for example, an ultrasonic type cutter after the chain cloth 81 including the branch portion 83 is formed. . On the other hand, the end of the back sheet portion 83b on the cloth mounting side is linearly along the longitudinal direction. Front side sheet portion 83a Among the ends of the cloth mounting side, the first position 83d corresponding to the vertex (83d) which protrudes most from the arc 83c to the cloth mounting side is aligned with the end of the back side sheet portion 83b on the cloth mounting side. The portion other than the first point 83d of the end on the cloth mounting side of the front side sheet portion 83a is offset from the end on the cloth mounting side of the back side sheet portion 83b to the element attaching portion 82 side. This offset is the largest at the second spot 83e corresponding to the arc ends (83e) of the arc 83c which is the most recessed to the element attaching portion 82 side in the end of the front side sheet portion 83a on the cloth mounting side. Therefore, the length of the front side sheet portion 83a in the width direction is changed over the entire longitudinal direction, and the length of the back side sheet 83b is the same in the width direction at the first point 83d, and the width direction is the same at the second point 83e and the back side sheet 83b. The difference in length becomes the largest. When the fabric 1 is sandwiched between the front side and the back side sheet portions 83a and 83b, the branch portion 83 can easily fold the front side sheet portion 83a with respect to the back side sheet portion 83b, thereby improving the workability at the time of sewing. . The circular arc 83c at the end of the front side sheet portion 83a can be formed by cutting the chain cloth 81 after being woven by a cutter. However, the method is not limited to this, and the arc 83c may be formed so that the weft yarn may be folded back at the end of the front side sheet portion 83a.

Fig. 9 shows a branch portion 93 which is a variation of the branch portion 83 of the chain belt 80 of Fig. 7, and the configuration other than the branch portion 93 is the same as that of Fig. 7, and the same reference numerals are attached. Similarly to the front side sheet portion 83a of the branch portion 83, the branch portion 93 of the branch portion 93 of the front side sheet portion 93a and the back side sheet portion 93b is formed such that the circular arc (83c) is continuous in the longitudinal direction. Among the ends of the front side of the front side sheet portion 93a, the first point 93aa corresponding to the apex of the circular arc and the first side of the mounting side of the back side sheet portion 93b correspond to the first point 93ba corresponding to the apex of the circular arc in the width direction. The branch starting points (85) are equally spaced apart, but are offset by a half arc in the length direction. In the end of the mounting side of the front side sheet portion 93a, the second point 93ab corresponding to both ends of the arc and the end of the mounting side of the back side sheet portion 93b are also at the second point 93bb corresponding to both ends of the arc. The length direction is staggered by a half arc. In this case, when the fabric 1 is sandwiched between the front side and the back side sheet portions 93a and 93b, the front side sheet portion 93a can be easily folded over with respect to the back side sheet portion 93b, and the workability at the time of sewing can be improved. The The arc of the end of the front side sheet portion 93a and the end of the back side sheet portion 93b can be formed by cutting the chain cloth 81 after being woven by a cutter. However, the present invention is not limited to this forming method, and an arc may be formed so that the weft yarns are folded back at the ends of the front side sheet portion 93a and the back side sheet portion 93b. Further, the end of the cloth mounting side in FIGS. 7 to 9 is not limited to an arc shape, and may be a triangular shape or a rectangular shape.

Further, the shapes may be formed on one of the ends of the cloth mounting side. That is, in one of the longitudinal direction of the fastener fabric, the front side sheet portion and the back side sheet portion may be shifted in the width direction. Here, the offset is in the width direction, and the chain tape or the zipper is observed from the front side (or the back side), and the back side sheet portion (or the front side sheet portion) can be seen.

In the above description, the chain belt and the zipper of the present invention are easy to fold when the fabric is interposed, and the following points may be referred to as features.
