Abstract
Description
Technical Field
[0001] The present invention relates to a template member suitable for sewing a fastener element member onto an object holding portion using a sewing machine, a sewing machine having the template member, and a sewing method for sewing a fastener element member onto an object holding portion using the template member. Background Art
[0002] Generally speaking, a zipper comprises: a pair of left and right zipper tapes, which are formed by forming a row of fastener elements at the side edges of the zipper tape; and a slider that slides along the left and right row of fastener elements. In a typical zipper, the zipper tape is used as an indispensable component (part) for constituting the zipper.
[0003] For example, International Publication No. 2018 / 142548 (Patent Document 1) describes a product with a zipper in which a zipper is formed without using a zipper tape.
[0004] For example Figure 11 As shown, the product (garment) 100 with a zipper described in Patent Document 1 is formed by attaching a fastener element member 102 to a material 101 of the garment 100 as a member to which the zipper is attached, by sewing using a sewing machine.
[0005] In this case, in the chain element component 102, a plurality of zipper elements 103 are formed at regular intervals on a rope-shaped fixing component 104 by injection molding. By directly sewing such a chain element component 102 to the clothing material 101, a chain element row is formed. In addition, a slider (not shown) is attached to the formed chain element row in a slidable manner. Thus, in Patent Document 1, a zipper that can open and close the left and right clothing materials 101 of a garment can be formed without using a zipper tape, thereby improving the lightweight and softness of the product (clothing).
[0006] In addition, Japanese Patent Application Laid-Open No. 2019-72466 (Patent Document 2) discloses a sewing machine for sewing the above-mentioned fastener element member 102 onto the clothing material 101 of the clothing. Figure 12 As shown, the sewing machine 110 of Patent Document 2 includes the following components as a conveying mechanism for conveying the element member 102: a conveying gear 111 that meshes with the zipper elements 103 of the element member 102; a conveying motor (not shown) that drives the conveying gear 111; and a needle plate portion (zipper guide) 112 that guides the element member 102. Furthermore, the sewing machine 110 of Patent Document 2 is provided with a feed tooth (not shown) as a conveying mechanism for conveying the material 101. By using the sewing machine 110 of Patent Document 2, the element member 102 described in Patent Document 1 can be directly sewn onto the material 101 of a product such as clothing.

[0009] Patent Document 1: International Publication No. 2018 / 142548
[0010] Patent Document 2: Japanese Patent Application Laid-Open No. 2019-72466 Summary of the Invention
[0011] Problems to be solved by the invention
[0012] When the fastener element member 102 described in Patent Document 1 is sewn onto a garment or other product, such as a garment, using the sewing machine 110 described in Patent Document 2, the fastener element member 102 is intermittently fed by the rotation of the feed gear 111 of the sewing machine 110. Simultaneously, the garment 101 is pressed by the needle plate 112 and the sewing machine presser foot 113 of the sewing machine 110, while the garment 101 is fed downstream by a feed tooth (not shown) that emerges and retracts relative to the needle plate 112. Thus, while the fastener element member 102 and the garment 101 are fed separately by independently driven feed mechanisms (i.e., the feed gear 111 and the feed tooth of the sewing machine 110), the sewing is performed by the raising and lowering of the sewing machine needle 114.
[0013] Furthermore, the plurality of zipper elements 103 are fixed to the fixing member 104, making it difficult for the element member 102 to expand or contract in the longitudinal direction. Meanwhile, the material (the member to which the zipper is attached) 101 to which the element member 102 is sewn has various properties depending on the characteristics and application of the product, such as softness and stretchability, which vary depending on the product (clothing).
[0014] Therefore, when the above-mentioned sewing machine 110 is used to sew the fastener element 102 to the clothing 101, there may be a difference in the feeding of the fastener element 102 and the feeding of the clothing 101 due to differences in the properties of the clothing 101. As a result, the clothing 101 to which the fastener element 102 is sewn may have an undulating shape or a partially protruding shape. In addition, since the clothing 101 expands and contracts during the sewing process, the length of the sewn portion of the clothing 101 is likely to vary in each sewing process step, resulting in deviations in product quality.
[0015] Furthermore, when manufacturing products (clothing) with zippers, a detachable insert that allows the left and right zipper element tapes to be separated, or a stopper that prevents the slider from falling off, is sometimes provided adjacent to the tooth array in the zipper formed on the product. In this case, although the various structural components forming the detachable insert or stopper are fixed to the fixing member of the tooth component together with the zipper elements, they are different in size and shape from the zipper elements. Therefore, it is sometimes difficult to use a single sewing machine to continuously sew the portion of a tooth component provided with multiple zipper elements and the portion provided with structural components such as the detachable insert.
[0016] In addition, in order to prevent the occurrence of such adverse conditions during the sewing process of the fastener element and the fabric, the operator sometimes presses the fabric while carefully guiding it downstream during the sewing process. However, such sewing operations are delicate and require experience, which also requires time and money for training the operators.
[0017] The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a template member, a sewing machine, and a sewing method that can easily and stably sew a fastener element member to an object member such as clothing.

[0042] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings while enumerating examples. In addition, the present invention is not limited to the embodiments described below, and various modifications may be made as long as the same structure as the present invention is substantially achieved and the same effects are achieved.
[0043] For example, in the following Examples 1 and 2, the case where the product with a zipper is a piece of clothing with a zipper is described, but the product with a zipper of the present invention is not limited to clothing (clothing), but includes a variety of products such as daily necessities such as shoes and bags, industrial equipment, various seats for cars, trains, aircraft, etc.

[0046] In the following description, the front-back direction is the direction in which the sewn objects (element members and clothing) are conveyed by the conveying mechanism of the sewing machine. Figure 2 The upper direction on the paper) is set as the front, and the opposite direction ( Figure 2 The up and down direction refers to the direction perpendicular to the flat mounting surface of the needle plate portion in the sewing machine, and the direction of the side where the sewing machine needle is arranged relative to the needle plate portion ( Figure 2 The direction of the front side in the paper) is set as the upward direction, and the opposite direction ( Figure 2 The left-right direction is a direction perpendicular to the conveying direction of the sewing article and parallel to the mounting surface of the needle plate. In the following embodiments 1 and 2, the direction on the side of the conveying mechanism of the sewing machine needle is set ( Figure 2 The right direction in the paper) is set as the right direction, and the opposite direction ( Figure 2 The left direction in the paper) is set as the left direction.
[0047] The sewing machine 1 (sewing machine body 30) of the present embodiment 1 is a zigzag lockstitch sewing machine that can sew in a zigzag pattern while the sewing machine needle 33 is swung in a direction intersecting the feeding direction of the sewing machine 1. Figure 7The fastener element 50 is sewn to the clothing material 5 as the target member. The sewing machine 1 forms sewing portions (sewing lines) on the front and back surfaces of the clothing material 5 using sewing threads composed of an upper thread (needle thread) and a lower thread (shuttle thread), and fixes the fastener element 50 to the clothing material 5 using the sewing portions.
[0048] Among them, the product with a zipper manufactured using the sewing machine 1 of this embodiment 1 is a piece of clothing with a zipper. In this piece of clothing, the tooth component 50 is directly sewn to the front body (especially, the placket) as the opening and closing part, thereby forming a zipper. In this case, the material 5 constituting the placket of the clothing is the object component (the component for installing the zipper) to which the tooth component 50 is sewn, and a tooth mounting edge for mounting the tooth component 50 is provided on the side edge of the material 5. The tooth component 50 is sewn to the tooth mounting edge of the material 5, thereby forming a tooth row composed of a plurality of zipper teeth 52 of the tooth component 50, and a slider not shown in the figure is slidably mounted on the tooth row.
[0049] In this embodiment 1, Figure 7 As shown, the fastener element member 50 includes: a plurality of independent synthetic resin fastener elements 52 (also referred to as individual fastener elements); and a cord-like fixing member 51 (also referred to as a connecting member) that connects the plurality of fastener elements 52 at regular intervals. The fixing member 51 is a cord body (also referred to as a braided yarn) formed by wrapping a core yarn around a sack weave portion knitted with a plurality of knitting yarns, and has flexibility (softness).
[0050] In the fastener element member 50, a plurality of fastener elements 52 are fixed to the fixing member 51 at equal intervals along the longitudinal direction of the fixing member 51 and in the same posture (orientation). These fastener elements 52 are formed integrally with the fixing member 51 by injection molding a thermoplastic resin such as polyamide, polyacetal, polypropylene, or polybutylene terephthalate onto a single fixing member 51. In the present invention, the materials of the fastener elements 52 and the fixing member 51 forming the fastener element member 50 are not particularly limited.
[0051] Each zipper element 52 of the element member 50 has: a main body portion, which is fixed to the fixing member 51; a neck portion, which extends from the main body portion in the left and right directions (width direction) of the element member 50 and has a necked shape; an engaging head portion, which further extends continuously in the left and right directions from the neck portion; and a shoulder portion, which protrudes from the neck portion to the front and rear of the fixing member 51 in the longitudinal direction in the shape of a thin plate.
[0052] Each zipper element 52 is fixed to the rope-shaped fixing member 51 in such a manner that the fixing member 51 only passes through the main body in the longitudinal direction (front-back direction). In this case, the main body of each zipper element 52 is formed so as to enclose the fixing member 51, and when observing a cross-section perpendicular to the longitudinal direction of the element member 50, the entire outer peripheral surface of the fixing member 51 is covered by the main body of the zipper element 52.
[0053] The sewing machine 1 of the first embodiment includes a sewing machine body 30 and a template member 10 mounted on the sewing machine body 30 .
[0054] For example Figure 4 As shown, the sewing machine main body 30 includes: a sewing table portion 31, which serves as a base on which a needle plate portion 32 is provided; a foot portion not shown in the figure, which is uprightly provided at the right end portion of the sewing table portion 31; an arm portion not shown in the figure, which extends from the upper end portion of the foot portion toward the left side; and a conveying mechanism 40, which conveys the template component 10 placed on the sewing table portion 31.
[0055] At the top end (left end) of the arm (not shown), a needle bar (not shown) on which a sewing machine needle 33 is mounted and a presser foot (not shown) on which a sewing machine presser foot 34 is mounted are arranged in a manner protruding downward. In this case, the needle bar is supported by a needle bar driving mechanism (not shown) so as to be able to rise and fall (move up and down) along the direction in which the sewing machine needle 33 extends (up and down direction). In addition, the needle bar is arranged so that the position of the sewing machine needle 33 can be moved in a direction intersecting with the conveying direction of the sewing machine 1 by using a needle swing mechanism (not shown). In addition, the sewing machine needle 33, the needle bar, and the needle bar driving mechanism of this embodiment are formed in substantially the same manner as those of a conventional general zigzag lockstitch sewing machine.
[0056] The sewing machine presser foot 34 is installed in a manner that allows it to be maintained in a pressing position for pressing the template member 10 placed on the sewing table portion 31, and in an ascending position (separated position) in which it is ascended from the pressing position and separated from the template member 10. The sewing machine presser foot 34 is provided with a slit-shaped through-hole 34a for the sewing machine needle 33 to pass through. In addition, the top end portion of the sewing machine presser foot 34 is formed in a shape that is bent upward toward the top edge of the presser foot (toward the rear) while extending, so as to guide the template member 10 toward the lower surface side of the sewing machine presser foot 34. In addition, in this embodiment 1, the sewing machine main body 30 can also be formed in a manner that does not provide a sewing machine presser foot 34.
[0057] The needle plate portion 32 of the sewing platform 31 has a flat upper surface on which the template member 10 is placed. A slit-shaped needle hole 32a for passing a sewing machine needle 33 is provided in the needle plate portion 32 in the left-right direction, corresponding to the position of the through hole 34a provided in the sewing machine presser foot 34. Furthermore, a rotary hook mechanism for storing the bobbin is provided on the lower side of the needle plate portion 32.
[0058] The conveying mechanism 40 for the template member 10 is arranged separately from the sewing machine presser foot 34 and the sewing machine needle 33. The conveying mechanism 40 includes: a mechanism body 41; a first conveying gear 42 rotatably provided at the lower end of the mechanism body 41; a second conveying gear 43 rotatably provided in front of (downstream of) the first conveying gear 42; a rotation drive unit (not shown) that rotates the first conveying gear 42 and the second conveying gear 43; and a first pressing unit 44 and a second pressing unit 45 that press the conveyed template member 10 from above.
[0059] The first conveying gear 42 and the second conveying gear 43 are spur gears having a plurality of teeth provided on their outer peripheries. The teeth of the first conveying gear 42 and the teeth of the second conveying gear 43 are respectively provided so as to be meshed with the rack portion 15 of the template member 10, which will be discussed later. The first conveying gear 42 and the second conveying gear 43 are supported by a gear support mechanism (not shown) of the mechanism main body 41 so as to be parallel to the upper surface of the needle plate portion 32 and to be rotatable. In addition, in the present embodiment 1, the first conveying gear 42 and the second conveying gear 43 are arranged separately from the upper surface of the needle plate portion 32, thereby providing a small gap between the lower surfaces of the first conveying gear 42 and the second conveying gear 43 and the upper surface of the needle plate portion 32.
[0060] The first and second conveying gears 42, 43 rotate while meshing with the rack portion 15 of the template member 10, thereby enabling the template member 10 to be moved in the front-to-back direction. In particular, in the first embodiment, in order to convey the template member 10 in the conveying direction (front-to-back direction) of the sewing machine 1, the feed gears provided in conventional sewing machines are not provided, and the template member 10 is conveyed solely by the rotation of the first and second conveying gears 42, 43. Furthermore, in the first embodiment, both the first and second conveying gears 42, 43 are provided in the conveying mechanism 40 as the gears for conveying the template member 10. However, in the present invention, only a single conveying gear may be provided in the conveying mechanism to convey the template member 10.
[0061] The rotation drive unit (not shown) of the conveying mechanism 40 includes a conveying motor that imparts rotational motion to the first conveying gear 42 and the second conveying gear 43, and a transmission mechanism that transmits the rotational force of the conveying motor to the first conveying gear 42 and the second conveying gear 43. In the present invention, the structure of the rotation drive unit is not particularly limited as long as the first conveying gear 42 and the second conveying gear 43 can be rotated and controlled. For example, a rotation drive unit having a structure substantially similar to that described in Patent Document 2 may be employed.
[0062] The first pressing portion 44 and the second pressing portion 45 of the conveying mechanism 40 are fixed to the mechanism main body 41. The first pressing portion 44 is arranged on the rear side (upstream side) of the second pressing portion 45. The lower surface of the first pressing portion 44 and the lower surface of the second pressing portion 45 are formed flat and are separated from the position of the upper surface of the needle plate portion 32 by the same distance. In addition, the first pressing portion 44 is provided in a manner that presses the template member 10 from the upper side in the range from the approximate center of the first conveying gear 42 to the front end of the second conveying gear 43 in the front-to-back direction. The second pressing portion 45 is provided in a manner that extends from the approximate center of the second conveying gear 43 to the rear side of the second conveying gear 43 in the front-to-back direction.
[0063] like Figure 5 and Figure 6 As shown, the template member 10 placed on the sewing machine body 30 includes: a chain element storage portion 11, which stores the chain element member 50; an object holding portion (clothing material holding portion) 12, which holds the object member (clothing material 5 of clothing) to which the chain element member 50 is sewn; a slit portion 13, which is provided along the chain element storage portion 11; a connecting portion 14, which is provided at the front end and the rear end of the template member 10 to connect the chain element storage portion 11 and the object holding portion 12; and a rack portion 15, which is provided at the side edge of the template member 10. In addition, in the present invention, the material of the template member 10 is not particularly limited.
[0064] The element receiving portion 11 of the template member 10 is provided along the longitudinal direction of the template member 10, substantially entirely from the front end to the rear end thereof, and is shaped to receive at least a portion of the fastener elements 52 in the element member 50. Specifically, the element receiving portion 11 includes a first support portion 16 on which the fastener elements 52 of the element member 50 are placed; a second support portion 17 disposed upwardly and spaced apart from the first support portion 16; an intermediate support portion 18 disposed between the first and second support portions 16, 17; and a receiving space 19 formed between the first and second support portions 16, 17, adjacent to the intermediate support portion 18. In this element receiving portion 11, the fastener elements 52 of the element member 50 are inserted into the receiving space 19 and held therebetween by the first and second support portions 16, thereby receiving a plurality of fastener elements 52.
[0065] The first support portion 16 of the element receiving portion 11 is formed in a comb-like shape. Specifically, the first support portion 16 comprises a plate-like first base portion 16a that is continuous in the longitudinal direction (front-back direction) of the template member 10, and a plurality of first protruding pieces 16b that protrude from the first base portion 16a in the width direction (left-right direction) toward the object holding portion 12.
[0066] The first protrusion 16b of the first support portion 16 is a portion that supports the zipper elements 52 of the element member 50 from the lower side and extends straight from the first base portion 16a in the width direction. A gap that is continuous with the slit portion 13 is provided between adjacent first protrusions 16b. The intervals between the first protrusions 16b formed along the longitudinal direction (the formation pitch of the first protrusions 16b) are the same size as the intervals between the zipper elements 52 formed along the longitudinal direction (the formation pitch of the zipper elements 52). Therefore, when the element member 50 is stored in the element storage portion 11, one zipper element 52 is placed on one first protrusion 16b.
[0067] In the first embodiment, the dimension of the first protrusion 16b protruding from the first base portion 16a (the width dimension of the first protrusion 16b) is larger than the width dimension of the meshing head of the zipper element 52 and smaller than the width dimension of the entire zipper element 52 (i.e., the maximum value of the width dimension). The length dimension of the first protrusion 16b (the length dimension from the front edge to the rear edge of the first protrusion 16b) is larger than half the length dimension of the meshing head of the zipper element 52 and smaller than the maximum value of the length dimension at the meshing head. In particular, in the case of the first embodiment, the length dimension of the first protrusion 16b is approximately the same as the minimum value of the length dimension at the neck of the zipper element 52. In addition, the width dimension refers to the dimension in the width direction (left-right direction) of the template member 10. The length dimension refers to the dimension in the length direction (front-back direction) of the template member 10.
[0068] The first protruding piece 16b has the aforementioned width and length dimensions, thereby facilitating the operation of attaching the fastener elements 52 of the element member 50 to the element receiving portion 11 of the template member 10. Furthermore, the first protruding piece 16b reliably supports each fastener element 52, allowing the element member 50 to be stably received in the element receiving portion 11. Furthermore, the first protruding piece 16b is formed to be thinner than the fastener elements 52.
[0069] The second support portion 17 of the element receiving portion 11 is formed of a leaf spring member and has a comb-like shape with fewer teeth than the first support portion 16. The second support portion 17 includes a second base portion 17a that is continuous in the longitudinal direction of the template member 10 and a plurality of second protruding pieces 17b that protrude from the second base portion 17a in the width direction toward the target holding portion 12.
[0070] In this case, the side edge of the second base portion 17a facing the slit portion 13 is positioned farther from the target holding portion 12 in the width direction than the side edge of the first base portion 16a facing the slit portion 13. The second protruding piece 17b is a portion that presses the fastener elements 52 of the element member 50 from above and holds the fastener elements 52 of the element member 50 between the first protruding piece 16b. The second protruding piece 17b extends straight from the second base portion 17a in the width direction.
[0071] The second protruding pieces 17b are arranged at regular intervals (forming pitches) in the longitudinal direction. Each second protruding piece 17b is arranged to correspond to the position of the first protruding piece 16b in the longitudinal direction. Furthermore, a gap continuous with the slit portion 13 is provided between adjacent second protruding pieces 17b. In this case, the longitudinal spacing of the second protruding pieces 17b is at least three times the spacing of the first protruding pieces 16b, and one second protruding piece 17b is provided for every three first protruding pieces 16b.
[0072] By increasing the spacing between the second protruding pieces 17b and making the number of second protruding pieces 17b smaller than the number of first protruding pieces 16b, when the fastener elements 52 of the element member 50 are mounted on the element receiving portion 11 of the template member 10, interference between the fastener elements 52 and the second protruding pieces 17b is less likely to occur, thereby facilitating the mounting of the element member 50. Furthermore, since the second supporting portion 17 is formed of a leaf spring, the second protruding pieces 17b can easily press the fastener elements 52 from above, allowing the first protruding pieces 16b and the second protruding pieces 17b to stably hold the fastener elements 52.
[0073] In addition, in the present invention, the number of the first protrusion 16b and the number of the second protrusion 17b are not limited and can be changed arbitrarily. It is preferred that the number of the second protrusion 17b is less than the number of the first protrusion 16b as in the present embodiment 1. Thus, as described above, the installation operation of the chain tooth component 50 to the template component 10 can be easily performed.
[0074] In this first embodiment, the second protruding piece 17b is formed so that its tip overlaps the tip of the first protruding piece 16b in the width direction. The second protruding piece 17b is larger than the first protruding piece 16b's tip from the second base portion 17a (i.e., its width). The length of the second protruding piece 17b (the dimension from the front edge to the rear edge of the second protruding piece 17b) is the same as the length of the first protruding piece 16b. These width and length dimensions of the second protruding piece 17b ensure an appropriate elastic force of the second protruding piece 17b formed by the leaf spring member, and furthermore, the first protruding piece 16b and the second protruding piece 17b can stably hold and store the fastener element 52.
[0075] The intermediate support portion 18 of the element storage portion 11 is formed integrally with the first support portion 16, and fixes the second base portion 17a of the second support portion 17. The intermediate support portion 18 is formed with the same thickness as the thickness of the zipper element 52, or is formed to be slightly thinner than the thickness of the zipper element 52. A storage recess 18a for inserting and storing a part of the engaging head of the zipper element 52 is provided on the side wall portion of the intermediate support portion 18 opposite to the storage space portion 19. The storage recess 18a is formed to be concave in the left and right directions relative to the front-to-back direction corresponding to the shape of the top portion of the engaging head that is curved into a convex shape. In addition, the storage recess 18a is provided in the entire intermediate support portion 18 along the up-down direction.
[0076] The storage recesses 18a are provided at regular intervals along the longitudinal direction in the intermediate support portion 18, corresponding to the positions of the first protruding pieces 16b. By storing a portion of the fastener elements 52 supported by the first protruding pieces 16b in the storage recesses 18a, the fastener elements 52 stored in the element storage portion 11 can be stably held in an appropriate posture.
[0077] Furthermore, a first step portion 21 is provided on the upper surface of the element storage portion 11 for contacting the first pressing portion 44 and the second pressing portion 45 of the feeding mechanism 40 provided on the sewing machine main body 30 (see FIG. Figure 3 When the template member 10 is placed on the sewing machine body 30, the first pressing portion 44 and the second pressing portion 45 of the conveying mechanism 40 are brought into contact with the first step 21 of the element receiving portion 11, thereby enabling the template member 10 to be placed at a predetermined position on the sewing machine body 30. This stabilizes the position of the template member 10 relative to the sewing machine body 30. Furthermore, when the template member 10 is conveyed by the first conveying gear 42 and the second conveying gear 43 of the sewing machine body 30, the contact between the first pressing portion 44 and the second pressing portion 45 and the first step 21 facilitates the conveying direction of the template member 10 in the front-rear direction.
[0078] The object holding portion (clothing holding portion) 12 of the template member 10 includes a first plate portion 12a, which is a plate-shaped portion for placing the clothing 5, and a second plate portion 12b, which is a plate-shaped portion disposed above the first plate portion 12a. The object holding portion 12 holds the clothing 5 in place by sandwiching at least a portion of the clothing 5 between the first plate portion 12a and the second plate portion 12b. The first plate portion 12a has a flat upper surface, which is a surface for placing the clothing 5, and a flat lower surface, which is disposed opposite the upper surface. The second plate portion 12b has a flat lower surface, which faces the first plate portion 12a, and an upper surface, which is disposed opposite the lower surface.
[0079] In this first embodiment, magnets (not shown) are provided at corresponding positions on the first plate portion 12a and the second plate portion 12b. When the clothing 5 is placed on the first plate portion 12a, the magnetic force between the magnets on the first plate portion 12a and the magnets on the second plate portion 12b causes the second plate portion 12b to be placed on the clothing 5. This allows the second plate portion 12b to be superimposed on the first plate portion 12a at a predetermined position across the clothing 5. Furthermore, the superimposed state of the first and second plate portions 12a, 12b can be maintained. This allows the clothing 5 to be stably held between the first and second plate portions 12a, 12b.
[0080] In this first embodiment, an anti-slip tape that increases frictional resistance may be bonded to the upper surface of the first plate portion 12a and / or the lower surface of the second plate portion 12b. This can more effectively prevent the garment 5 held between the first and second plate portions 12a, 12b from shifting. Alternatively, the first and second plate portions 12a, 12b may be connected by a hinge. This allows the second plate portion 12b to be stably superimposed on the first plate portion 12a at a predetermined position.
[0081] The side edge of the second plate portion 12b on the side opposite to the element receiving portion 11 is provided with: a second step portion 22, so that the sewing machine presser foot 34 provided to the sewing machine main body 30 contacts the second step portion 22; and a presser foot contact surface 23, which extends from the second step portion 22 toward the element receiving portion 11 (refer to Figure 3 and Figure 5 When the template member 10 is placed on the sewing machine main body 30, the sewing machine presser foot 34 is brought into contact with the second step portion 22 and the presser foot contact surface 23 provided on the object holding portion 12, thereby allowing the template member 10 to be placed and pressed at a predetermined position on the sewing machine main body 30. This further stabilizes the position of the template member 10 relative to the sewing machine main body 30. Furthermore, when the template member 10 is conveyed by the first conveying gear 42 and the second conveying gear 43 of the sewing machine main body 30, the contact between the second step portion 22 and the presser foot contact surface 23 and the sewing machine presser foot 34 allows the template member 10 to be smoothly conveyed in the front-to-back direction.
[0082] A reinforcement portion 24 formed by thickening the second plate portion 12 b is provided on the left side of the second step portion 22 (the side in the direction away from the element accommodating portion 11 ) of the second plate portion 12 b.
[0083] A slit portion 13 is provided between the element receiving portion 11 and the object holding portion 12 of the template member 10, extending vertically through the template member 10 to allow the sewing machine needle 33 to pass therethrough. The slit portion 13 is provided continuously along the longitudinal direction of the template member 10, extending between the front connecting portion 14 and the rear connecting portion 14 of the template member 10.
[0084] The front and rear ends of the template member 10 are provided with connecting portions 14 (see FIG. Figure 5 In the first embodiment, the connecting portion 14 is integrally connected to a portion of the intermediate supporting portion 18 of the element accommodating portion 11 , the first supporting portion 16 , and the first plate portion 12 a of the target holding portion 12 .
[0085] The rack portion 15 of the template member 10 is provided at the right edge portion (the side edge portion on one side in the left-right direction) of the template member 10 along the entire longitudinal direction of the template member 10. In this case, the element receiving portion 11 of the template member 10 is provided at a position sandwiched between the slit portion 13 and the rack portion 15 along the longitudinal direction. In other words, the rack portion 15 is provided along the longitudinal direction on the opposite side of the slit portion 13 in the width direction relative to the element receiving portion 11.
[0086] The rack portion 15 has a plurality of teeth 15 a formed by cutting the right edge of the template member 10 , and is formed to be engageable with a first conveying gear 42 and a second conveying gear 43 provided to the sewing machine body 30 .
[0087] Hereinafter, a sewing method according to the first embodiment of the present invention for sewing the element member 50 to the clothing material 5 of clothing using the above-mentioned sewing machine 1 will be described.
[0088] First, the fastener element member 50 , the clothing material 5 cut into a predetermined shape, and the aforementioned template member 10 are prepared.
[0089] Next, the prepared tooth member 50 is stored and held in the tooth storage portion 11 of the template member 10. In this case, the tooth member 50 is inserted from the slit portion 13 of the template member 10, and one or more zipper teeth 52 arranged at one end of the tooth member 50 are stored in one end of the tooth storage portion 11. Specifically, the engaging head of the zipper tooth 52 is inserted between the first protrusion 16b of the first support portion 16 and the second protrusion 17b of the second support portion 17 in the tooth storage portion 11 and stored in the storage space portion 19. At this time, a part of the engaging head is inserted into the storage recess 18a of the intermediate support portion 18. Thus, one end of the tooth member 50 can be easily stored in the tooth storage portion 11.
[0090] Next, the fastener elements 52 are sequentially inserted and housed in the element housing portion 11 from one end portion to the other end portion of the element member 50. Figure 7 As shown, the entire fastener element member 50 can be held in the element receiving portion 11 of the template member 10. In particular, in the first embodiment, the number of second protruding pieces 17b provided in the element receiving portion 11 is reduced compared to the number of first protruding pieces 16b provided. This facilitates insertion of the zipper elements 52 from the second supporting portion 17 side of the element receiving portion 11. Therefore, the operation of storing and installing the fastener element member 50 in the template member 10 can be easily performed in a relatively short time.
[0091] After the element member 50 is secured to the template member 10, the material 5, which is the member to be attached to the zipper, is secured to the target retaining portion 12 of the template member 10. In this case, the second plate portion 12b of the template member 10 is lifted and separated from the first plate portion 12a, and the material 5 is placed on the first plate portion 12a. At this point, one side edge of the material 5 placed on the first plate portion 12a is brought into contact with all of the zipper elements 52 of the element member 50 housed in the element housing portion 11.
[0092] Next, the second plate portion 12b is placed at a predetermined position on the clothing 5, thereby overlapping the second plate portion 12b with the first plate portion 12a and the clothing 5. By placing the second plate portion 12b on the clothing 5 in this manner, the clothing 5 is sandwiched between the first plate portion 12a and the second plate portion 12b by the magnetic force of the unillustrated magnet provided on the first plate portion 12a and the unillustrated magnet provided on the second plate portion 12b. At this time, it is preferable to maintain the clothing 5 on the object holding portion 12 in a state where appropriate tension is applied in the longitudinal direction. Thus, in the template member 10, the chain tooth member 50 and the clothing 5 can be maintained in appropriate positions, respectively, and in a state of contact with each other. In addition, the holding state of the chain tooth member 50 and the clothing 5 can be stably maintained.
[0093] Next, the template member 10, holding the element member 50 and the material 5, is placed on the sewing machine body 30. In this case, one longitudinal end of the template member 10 is placed on the needle plate 32 of the sewing machine body 30, so that the lower surface of the first plate portion 12a of the template member 10 and the lower surface of the first support portion 16 of the element receiving portion 11 contact the upper surface of the needle plate 32. Furthermore, the rack portion 15 of the template member 10 is meshed with the first and second feed gears 42 and 43 of the sewing machine body 30. Simultaneously, the first step 21 of the template member 10 is brought into contact with the first and second pressing portions 44 and 45 of the sewing machine body 30. Furthermore, the sewing machine presser foot 34 is lowered so that it contacts the second step 22 and presser foot contact surface 23 of the template member 10, thereby pressing the template member 10 with the sewing machine presser foot 34. Thus, the template member 10 is properly placed in the sewing machine body 30.
[0094] Afterwards, the fastener element member 50 held by the template member 10 is sewn to the clothing 5. In this case, the coordinate data of the needle drop position at which the sewing machine needle 33 is lowered is pre-set in the sewing machine body 30, and the sewing process can be automatically performed using a program pre-programmed into the sewing machine body 30. In the present invention, the needle drop position of the sewing machine 1, the stitch pattern formed by the sewing process, and the like are not particularly limited.
[0095] During the sewing process performed by the sewing machine main body 30, the first conveying gear 42 and the second conveying gear 43 of the conveying mechanism 40 are rotated at a predetermined speed and timing by a rotation drive unit (not shown), thereby enabling the template member 10 to be automatically and intermittently or continuously conveyed toward the downstream side of the conveying direction (the front side of the front-to-back direction).
[0096] In particular, in the first embodiment, the feed teeth provided in conventional general sewing machines are not used, and the template member 10, which already holds the fastener element 50 and the clothing 5, is conveyed solely by the conveying mechanism 40 having the first conveying gear 42 and the second conveying gear 43 rotating at the same speed. Therefore, in the first embodiment, compared to the case where the template member 10 is conveyed solely by, for example, conventional feed teeth, the speed and timing of conveying the template member 10 can be easily and accurately controlled, thereby enabling the template member 10 to be conveyed stably, intermittently or continuously, under predetermined conditions.
[0097] Furthermore, in the first embodiment, when conveying the template member 10, the first pressing portion 44 and the second pressing portion 45 of the sewing machine body 30 are brought into contact with the first step 21 of the template member 10, and the sewing machine presser foot 34 is brought into contact with the second step 22 and the presser foot contact surface 23 of the template member 10. Thus, the template member 10 can be conveyed stably and linearly forward. At this time, the operator can assist in conveying the template member 10 by placing their hands on the template member 10, or they can convey the template member 10 without placing their hands on the template member 10.
[0098] Furthermore, while the template member 10 is conveyed forward, the sewing machine needle 33 is raised and lowered to pass through the slit portion 13 of the template member 10 and the gap between the first protruding piece 16b and the gap between the second protruding piece 17b that are connected to the slit portion 13, while performing flat sewing. Thus, a zigzag sewn portion, such as that described in Patent Document 1, can be formed between the material 5 and the fastener element 50 by the sewing thread, and the fastener element 50 can be sewn to the side edge of the material 5 and fixed by this sewn portion.
[0099] By performing the above-mentioned sewing process, even without manually pressing and guiding the clothing 5 during the sewing process, the element member 50 can be easily sewn to the clothing 5 using the sewing machine 1. Thus, the component part of the clothing formed by sewing the element member 50 to the clothing 5 can be stably manufactured.
[0100] In particular, in the first embodiment, the material 5 and the fastener element 50 are held in an appropriately positioned relationship on the template member 10, while the template member 10 is transported by the single transport mechanism 40 and the sewing machine body 30 performs the sewing process. Consequently, even if the material 5 is flexible or stretchable, the material 5 is prevented from stretching during sewing, allowing for automatic and stable transport of the material 5. Consequently, the material 5 sewn with the fastener element 50 is less likely to develop defects such as undulating shapes or locally protruding shapes, allowing for the production of garment components in which the fastener element 50 is precisely and satisfactorily attached to the predetermined position of the material 5.
[0101] Furthermore, when a plurality of garment components are manufactured using the sewing method of the first embodiment, garment components of the same quality can be manufactured stably with well-finished sewn portions. Therefore, for example, the length of the sewn portion of the garment material 5 can be less likely to vary. This stabilizes the quality of the garment with a zipper.
[0102] Furthermore, in the sewing method of the first embodiment, the template member 10 holding the material 5 and the tooth member 50 can be automatically conveyed by the first conveying gear 42 and the second conveying gear 43 of the conveying mechanism 40. Therefore, it is no longer necessary for an operator to press the material 5 and carefully guide it during the sewing process, as in the past, and the sewing process can be performed easily and smoothly. Therefore, the burden on the operator can be greatly reduced, and the time and cost required for operator training can be reduced.
[0103] Example 2
[0104] Figure 8 It is a perspective view schematically showing the main parts of the sewing machine of the second embodiment. Figure 9 It is a top view showing a part of the fastener element member used in the present second embodiment. Figure 10 It is enlarged and schematically represented Figure 8 A perspective view of the element receiving portion of the template member shown.
[0105] In addition, in this embodiment 2, the components or parts having substantially the same structure as the components or parts described in the above-mentioned embodiment 1 are denoted by the same reference numerals, and their description is omitted.
[0106] The zippered product manufactured using the sewing machine 2 of the second embodiment is a zippered garment, in which a fastener element member 50a is sewn to the side edge (element attachment edge) of the material 5 of the garment. Furthermore, in the case of the second embodiment, a fastener element row consisting of a plurality of fastener elements 52 of the fastener element member 50a is formed on the side edge of the material 5, and a detachable insert having an inserting rod portion and a seating rod portion (not shown) is provided adjacent to one end of the fastener element row.
[0107] For example Figure 9 As shown, the chain element member 50a includes: a longitudinal fixing member 51; a plurality of independent zipper elements 52 fixed to the fixing member 51; and an inserter component (inserter structure component) 53 fixed to the fixing member 51. In this case, the fixing member 51 and the zipper elements 52 are formed in the same manner as the chain element member 50 of the aforementioned embodiment 1. In addition, in this embodiment 2, among the plurality of zipper elements 52 provided in the chain element member 50a, the zipper element 52 arranged at the end portion (e.g., the front end portion) closest to the side in the longitudinal direction is set as the first chain element 52a.
[0108] The insert rod forming portion 53 is a component that forms the insert rod portion of the detachable insert by sewing the fastener element 50a to the clothing material 5. The insert rod forming portion 53 is fixed to the fixing member 51 at a position adjacent to the first fastener element 52a in the longitudinal direction of the fastener element 50a, and a predetermined gap is provided between the insert rod forming portion 53 and the first fastener element 52a.
[0109] The plunger component 53 includes a substantially rectangular parallelepiped plunger body 53a that encloses the fixing member 51; a fin portion 53b that extends from one side of the plunger body 53a in the width direction (left-right direction); an engaging portion 53c and a tab portion 53d that protrude from the other side of the plunger body 53a in the width direction. The one side and the other side of the plunger body 53a refer to the side faces of the plunger body 53a that face opposite sides in the width direction.
[0110] The plunger body 53a has a flat upper surface and a flat lower surface perpendicular to the vertical direction. The thickness dimension between the upper and lower surfaces of the plunger body 53a is the same as or substantially the same as the thickness dimension between the upper and lower surfaces of the main body of the zipper element 52. The plunger body 53a is fixed to the fixing member 51 in such a manner that the plunger body 53a encloses the fixing member 51 and the fixing member 51 passes through the plunger body 53a in the longitudinal direction.
[0111] The fin 53b is connected to the center of the plunger body 53a in the thickness direction and has an outer opening 53e and two inner openings 53f extending therethrough in the vertical direction for the sewing needle 33 of the sewing machine 2 to pass therethrough.
[0112] The outer opening portion 53e is provided linearly and continuously along the longitudinal direction in a portion of the fin portion 53b farther from the plunger body portion 53a than the widthwise center position in the widthwise direction of the element member 50a.
[0113] The two inner openings 53f have a Figure 9 ) is in a roughly circular or roughly elliptical shape. The two inner opening portions 53f are provided in the area between the insert rod main body portion 53a and the outer opening portion 53e in the width direction. In the sewing process performed by the sewing machine 2, the sewing machine needle 33 penetrates the outer opening portion 53e and the inner opening portion 53f provided to the fin portion 53b to form the sewing portion of the sewing line into a serrated shape. By using the serrated sewing portion to press the fin portion 53b toward the clothing 5, the insert rod constituting portion 53 is sewn to the clothing 5. In addition, in the present invention, as long as the insert rod constituting portion 53 can be sewn to the clothing 5 using the sewing machine 2, the shape and size of the insert rod constituting portion 53 (for example, the shape and size of the hole portion provided to allow the sewing machine needle 33 to penetrate the fin portion 53b) are not particularly limited.
[0114] The engaging portion 53c of the inserter-forming portion 53 is located at the end (rear end) of the inserter body 53a, closer to the first element 52a, in the longitudinal direction of the element member 50a. The tab 53d of the inserter-forming portion 53 is located farther from the first element 52a in the longitudinal direction than the engaging portion 53c. Furthermore, the engaging portion 53c is formed so as to be engageable with the first element of the element member having a seat-forming portion (not shown) that forms a detachable insert.
[0115] The sewing machine 2 of the second embodiment forms a zigzag sewing portion (not shown) on the clothing 5 and uses the sewing portion to sew the clothing 5. Figure 9 The fastener element member 50a is fixed to the zigzag lockstitch sewing machine of the clothing 5. The sewing machine 2 includes a sewing machine body 30 and a template member 60 mounted on the sewing machine body 30. The sewing machine body 30 is formed similarly to the sewing machine body 30 described in the first embodiment.
[0116] The template member 60 of this embodiment 2 has: a chain element storage portion 61, which stores a part of the chain element member 50a; an object holding portion (clothing holding portion) 62, which holds the clothing material 5 of the clothes; a slit portion 63, which is arranged along the chain element storage portion 61; a connecting portion 64, which is arranged at the front end portion of the template member 60 to connect the chain element storage portion 61 and the object holding portion 62; and a rack portion 65, which is arranged at the side edge portion of the template member 60.
[0117] The element storage portion 61 is provided along the longitudinal direction of the template member 60. The element storage portion 61 includes a first support portion 66 on which a portion of the element member 50a is placed; a second support portion 67 disposed upwardly and spaced apart from the first support portion 66; an intermediate support portion 68 and an alignment portion 70 disposed between the first support portion 66 and the second support portion 67; and a storage space 69 formed between the first support portion 66 and the second support portion 67 so as to be adjacent to the intermediate support portion 68. Furthermore, a step portion 71 is provided on the upper surface of the element storage portion 61 to allow the first pressing portion 44 and the second pressing portion 45 of the feed mechanism 40 provided on the sewing machine body 30 to contact each other.
[0118] The first support portion 66 is formed substantially similarly to the first support portion 16 of the aforementioned first embodiment. Specifically, the first support portion 66 has a first base portion 66a that is continuous in the longitudinal direction (front-to-back direction) and a plurality of first protrusions 66b that protrude straight from the first base portion 66a in the width direction (left-to-right direction), forming a comb-like shape. Gaps that are continuous with the slit portion 63 are provided between adjacent first protrusions 66b. Furthermore, the pitch of the first protrusions 66b along the longitudinal direction is the same as the pitch of the zipper elements 52 of the element member 50a along the longitudinal direction.
[0119] The second support portion 67 is formed of a leaf spring member. Furthermore, the second support portion 67 has a second base portion 67a fixed to the intermediate support portion 68 and a plurality of second protruding pieces 67b protruding from the second base portion 67a, forming a comb-like shape. In this second embodiment, the plurality of second protruding pieces 67b correspond to the first protruding pieces 66b and are arranged in the longitudinal direction at the same number and pitch as the first protruding pieces 66b.
[0120] Furthermore, the second protruding piece 67b is formed so that its tip overlaps the tip of the first protruding piece 66b. This allows the plunger-forming portion 53 to be stably held between the first and second protruding pieces 66b, 67b. Furthermore, in the present invention, the number, spacing, and width of the first and second protruding pieces 66b, 67b are not particularly limited.
[0121] The intermediate support portion 68 is formed integrally with the first support portion 66 and fixes the second base portion 67a of the second support portion 67. The intermediate support portion 68 is formed to have the same thickness as the thickness of the insert rod body portion 53a, or is formed to be slightly thinner than the thickness of the insert rod body portion 53a. The side wall portion of the intermediate support portion 68 opposite to the storage space portion 69 is provided with: a first storage recess 68a, which is provided for inserting and storing a portion of the engaging head of the zipper element 52; and a second storage recess 68b, which is provided for inserting and storing a portion of the engaging portion 53c of the insert rod constituting portion 53. By respectively storing a portion of the zipper element 52 and a portion of the insert rod constituting portion 53 in the first storage recess 68a and the second storage recess 68b, the zipper element 52 and the insert rod constituting portion 53 stored in the element storage portion 61 can be stably maintained in an appropriate posture. Furthermore, in the second embodiment, the first housing recess 68 a and the second housing recess 68 b may be formed in the same shape as each other.
[0122] The alignment portion 70 is formed at a predetermined longitudinal position, extending in the width direction from the intermediate support portion 68 toward the object holding portion 62. A groove portion 70a is formed along the longitudinal direction on the lower surface of the alignment portion 70 to accommodate the fixing member 51 extending from the inserter forming portion 53 of the element member 50a. This alignment portion 70 stably accommodates and holds the element member 50a at a predetermined longitudinal position within the element receiving portion 61 by bringing the inserter forming portion 53 into contact with the alignment portion 70 when the inserter forming portion 53 is received in the element receiving portion 61.
[0123] Furthermore, in the second embodiment, the positioning portion 70 may be formed so as to be attachable to and detachable from the intermediate support portion 68. Furthermore, the positioning portion 70 may be formed so as to be positionally adjustable relative to the intermediate support portion 68. Thus, even if the counterpart components, such as the insert forming portion and the seat forming portion, to be housed in the element housing portion of the template member have various shapes and lengths, the counterpart components can be housed and held in the appropriate position in the element housing portion.
[0124] The chain element storage portion 61 of this embodiment 2 has: a first storage portion (storage portion for inserting rods) 76, which stores the inserting rod forming portion 53 of the chain element component 50a; and a second storage portion (storage portion for zipper chain elements) 77, which stores one or more zipper chain elements 52 arranged near the inserting rod forming portion 53 of the chain element component 50a.
[0125] In addition, the size (especially the size in the length direction) of the first receiving portion 76 in the element receiving portion 61 can be changed in accordance with the length dimension of the object component (in the present embodiment 2, the insert forming portion 53) held in the element receiving portion 61. That is, when the length dimension of the object component is smaller than that of the present embodiment 2, a portion of the first receiving portion 76 of the present embodiment 2 functions as the second receiving portion 77. On the other hand, when the length dimension of the object component is larger than that of the present embodiment 2, a portion of the second receiving portion 77 of the present embodiment 2 functions as the first receiving portion 76. Depending on the circumstances, the second receiving portion 77 may not be provided, and the element receiving portion 61 may be formed using only the first receiving portion 76. In addition, in the present embodiment 2, the first supporting portion 66 and the second supporting portion 67 in a portion of the element receiving portion 61 (for example, the portion forming the first receiving portion 76) may not have the comb-like shape described above, but may be formed in other shapes such as a rectangular plate-like shape.
[0126] In the template member 60 of this second embodiment, the target holding portion 62 for holding the clothing 5 includes a first plate portion (not shown) on which the clothing 5 is placed, and a second plate portion 62b disposed above the first plate portion. Furthermore, magnets (not shown) are provided on each of the first and second plate portions 62b, enabling the second plate portion 62b to be superimposed on the first plate portion at a predetermined position. The target holding portion 62 holds the clothing 5 in place by sandwiching at least a portion of the clothing 5 between the first and second plate portions 62b.
[0127] The length and width dimensions of the first plate portion of the present embodiment 2 are formed to be larger than the length and width dimensions of the second plate portion 62b. Thus, the clothing 5 can be stably placed on the first plate portion. The first plate portion and the second plate portion 62b of the present embodiment 2 have an avoidance portion 62c provided in a manner of cutting off the side edge portion opposite to the tooth receiving portion 61. By providing such an avoidance portion 62c, when the clothing 5 is fixed to the object retaining portion 62, the first plate portion and the second plate portion 62b can be prevented from interfering with the rod forming portion 53 of the tooth member 50a. In addition, the peripheral portion of the portion of the clothing 5 to which the rod forming portion 53 is fixed can be easily retained by clamping the first plate portion and the second plate portion 62b.
[0128] The rack portion 65 of the template member 60 is provided on the right edge portion of the template member 60 over the entire longitudinal direction of the template member 60. The rack portion 65 has a plurality of teeth 65a that mesh with the first and second feed gears 42, 43 provided on the sewing machine body 30.
[0129] When sewing the fastener element 50a to the clothing material 5 using the sewing machine 2 of the second embodiment, first, similarly to the case of the first embodiment, the fastener element 50a, the clothing material 5 cut into a predetermined shape, and the template element 60 are prepared.
[0130] Next, the prepared element member 50a's insert rod forming portion 53 and the three zipper elements 52 adjacent to the insert rod forming portion 53 are stored and held in the element receiving portion 61 of the template member 60. In this case, the element member 50a is inserted from the slit portion 63 of the template member 60, and the insert rod forming portion 53 and the zipper elements 52 are inserted into the receiving space portion 69 of the element receiving portion 61. Figure 8 As shown, a part of the element member 50 a can be easily accommodated in the element accommodating portion 61 .
[0131] Furthermore, the clothing material 5 is held by the object holding portion 62 of the template member 60. In this case, the clothing material 5 is placed on the first plate portion of the template member 60 so that the clothing material 5 and the fastener element 50a are in contact. Then, the second plate portion 62b is placed on the clothing material 5, thereby sandwiching the clothing material 5 between the first and second plate portions 62b and holding it. This allows the fastener element 50a and the clothing material 5 to be held in contact with each other on the template member 60 and to be fixed in their proper positions. Furthermore, the fastener element 50a and the clothing material 5 can be stably maintained.
[0132] Next, the template member 60 holding the fastener element 50a and the clothing 5 is placed on the sewing machine body 30. At this time, the rack portion 65 of the template member 60 is meshed with the first conveying gear 42 and the second conveying gear 43 of the sewing machine body 30. At the same time, the step portion 71 of the template member 60 is brought into contact with the first pressing portion 44 and the second pressing portion 45 of the sewing machine body 30. In addition, the sewing machine presser foot 34 is lowered, thereby pressing the template member 60 with the sewing machine presser foot 34. In this way, the template member 60 is properly placed on the sewing machine body 30.
[0133] After that, the tooth member 50a held by the template member 60 is sewn to the clothing 5. The sewing process of the second embodiment is substantially the same as the sewing process described in the first embodiment. While the template member 60 is stably conveyed in a straight line toward the front, the sewing machine needle 33 is raised and lowered to perform flat sewing, so that the portion of the tooth storage portion 61 held by the tooth member 50a (and further, the portion near it) can be automatically sewn to the side edge of the clothing 5 and fixed.
[0134] In addition, in the second embodiment, for example, the rack portion 65 of the template member 60 is provided with a Figure 8 When the shape shown is extended rearward, the template member 60 can be smoothly transported forward along the rack portion 65. Thus, not only the portion of the element member 50a held in the element receiving portion 61 but also the portion of the element member 50a not held in the element receiving portion 61 can be sewn to the clothing 5 and fixed.
[0135] By performing the sewing process of the second embodiment described above, the fastener element member 50a can be easily and stably sewn to the clothing material 5. Furthermore, the clothing material 5 is less likely to expand or contract during the sewing process, and the clothing material 5 to which the fastener element member 50a is sewn is less likely to develop defects such as undulating shapes or locally protruding shapes. This allows the production of a garment component in which the fastener element member 50a is accurately and satisfactorily attached to a predetermined position on the clothing material 5.
[0136] Furthermore, when a plurality of garment components are produced by sewing, garment components of the same quality with well-finished sewing portions can be stably produced, and it is difficult for the length of the sewing portion of the clothing material 5 to vary. Thus, the quality of the garment with a zipper can be stabilized.
[0137] Furthermore, as also described in the aforementioned first embodiment, the burden on the operators can be significantly reduced, and the time and cost required for operator training can be reduced.
[0138] Furthermore, in the above-described embodiments 1 and 2, the template members 10 and 60 are transported downstream by the transport gears (the first transport gear 42 and the second transport gear 43) of the transport mechanism 40 provided on the sewing machine body 30. However, in the present invention, instead of providing the transport gears on the sewing machine body 30, the sewing machine may be constructed so that the needle plate portion of the sewing machine body is movable in the front-to-back direction and the template member can be fixed to the needle plate portion. Even when such a sewing machine is used, the template members 10 and 60 can be transported stably in a straight line along the front-to-back direction while the tooth members 50 and 50a can be accurately and satisfactorily attached to the predetermined position of the material 5.
