Description

Fixing member, sewing machine, and sewing method Technical Field The present invention relates to a fixing member used in a sewing process for sewing a fastener element member to a cloth member using a sewing machine, a sewing machine having the fixing member, and a sewing method for sewing a fastener element member to a cloth member using a sewing machine. Background The slide fastener generally includes a pair of right and left fastener stringers in which fastener element rows are formed at tape side edges of the fastener stringers, and a slider that slides along the right and left fastener element rows. In a conventional slide fastener, a fastener tape is used as an indispensable component constituting the slide fastener. On the other hand, for example, international publication No. 2018/142548 (patent document 1) describes a tape-fastener product in which a fastener is formed without using a fastener tape. For example, as shown in fig. 8, the fastener-attached article (garment) 100 described in patent document 1 is formed by attaching the element member 102 to the cloth member 101 of the garment 100 as a fastener attachment member by sewing with a sewing machine. In this case, in the fastener element member 102, a plurality of fastener elements 103 are formed on a string-like fixing member 104 at fixed intervals by injection molding. The fastener element 102 is directly sewn to the cloth member 101 to form a fastener element row. A slider, not shown, is slidably attached to the formed element row. In this way, in patent document 1, since the slide fastener of the cloth member 101 capable of opening and closing the left and right clothes can be formed without using the slide fastener tape, the weight of the product (clothes) can be reduced and the flexibility can be improved. In addition, japanese patent application laid-open No. 2019-72466 (patent document 2) discloses a sewing machine for sewing the fastener element 102 to the cloth member 101 of the clothing. For example, as shown in fig. 9, the sewing machine 110 of patent document 2 includes, as a conveying mechanism for conveying the fastener element 102, a conveying gear 111 that meshes with the fastener element 103 of the fastener element 102, a conveying motor, not shown, that drives the conveying gear 111, and a needle plate portion (fastener guide) 112 that guides the fastener element 102. In the sewing machine 110 of patent document 2, a feed gear, not shown, is provided as a feed mechanism for conveying the cloth member 101. By using the sewing machine 110 of patent document 2, the fastener element 102 described in patent document 1 can be directly joined to the cloth member 101 of a product such as clothing. Prior art literature Patent literature Patent document 1 International publication No. 2018/142548 Patent document 2 Japanese patent application laid-open No. 2019-72466 Disclosure of Invention Problems to be solved by the invention When the fastener element 102 described in patent document 1 is sewn to the cloth member 101 using the sewing machine 110 described in patent document 2, the fastener element 102 is intermittently conveyed by rotation of the conveying gear 111 of the sewing machine 110. At the same time, the cloth member 101 is conveyed downstream by feeding teeth, not shown, which are exposed to the needle plate portion 112 while the cloth member 101 is pressed by the needle plate portion 112 and the sewing machine presser foot 113 of the sewing machine 110. Accordingly, the fastener element 102 and the cloth member 101 are sewn by the sewing needle 114 while being conveyed by the conveying mechanisms (i.e., the conveying gear 111 and the feed gear of the sewing machine 110) which are driven independently of each other. In this case, the fastener element 102 is fixed to the fixing member 104, and the plurality of fastener elements 103 are less likely to expand and contract in the longitudinal direction. On the other hand, the cloth member (fastener attaching member) 101 to which the element member 102 is sewn has various properties according to the characteristics, uses, and the like of the product. The properties of cloth members such as softness and stretchability vary depending on the product (clothing). Therefore, when the sewing process for sewing the fastener element 102 to the cloth member 101 using the sewing machine 110 as described above is performed, there is a case where a difference occurs between the conveyance of the fastener element 102 and the conveyance of the cloth member 101 due to the property of the cloth member 101 or the like. As a result, the cloth member 101 to which the element member 102 is sewn may have a corrugated shape, a partially ejected shape, a shape in which wrinkles (puckering) are generated, or the like. In addition, the cloth member 101 stretches during the sewing process, and thus the length of the sewn portion of the cloth member 101 may vary, and as a result, variations in the qual
