FIXING MEMBER, SEWING MACHINE, AND SEWING METHOD

The present invention relates to a fixing member used in a sewing process of sewing a fastener element member to a fabric member using a sewing machine, a sewing machine having the fixing member, and sewing to sew the fastener element member to the fabric member using the sewing machine. Regarding the method.

A slide fastener generally has a pair of left and right fastener stringers with element rows formed on the tape side edges of a fastener tape, and a slider that slides along the left and right element rows. In general slide fasteners, a fastener tape is used as an indispensable member for constructing the slide fastener.

On the other hand, for example, International Publication No. 2018/142548 (Patent Document 1) describes a product with a slide fastener in which a slide fastener is formed without using a fastener tape.
For example, as shown in FIG. 8, in a product (clothing) 100 with a slide fastener described in Patent Document 1, an element member 102 is attached to a fabric member 101 of a clothing 100, which is a fastener receiving member, by sewing using a sewing machine. It is formed by being

In this case, in the element member 102, a plurality of fastener elements 103 are formed at regular intervals on a string-shaped fixing member 104 by injection molding. By directly sewing such an element member 102 to the fabric member 101, an element row is formed. Also, a slider (not shown) is slidably attached to the formed element row. As a result, in Patent Document 1, a slide fastener capable of opening and closing the fabric members 101 on the left and right sides of the garment can be formed without using fastener tapes, thus reducing the weight of the product (clothing) and improving flexibility. can be realized.

Further, Japanese Patent Application Laid-Open No. 2019-72466 (Patent Document 2) discloses a sewing machine for sewing the element member 102 as described above to the fabric member 101 of clothes. For example, as shown in FIG. 9, the sewing machine 110 of Patent Document 2 has a transport gear 111 that meshes with the fastener element 103 of the element member 102 and a transport gear 111 that drives the transport gear 111 as a transport mechanism for transporting the element member 102 . and a throat plate portion (fastener guide) 112 for guiding the element member 102 . Further, the sewing machine 110 of Patent Document 2 is provided with a feed dog (not shown) as a feed mechanism for conveying the fabric member 101 . By using such a sewing machine 110 of Patent Document 2, it is possible to directly sew the element member 102 described in Patent Document 1 to the fabric member 101 of a product such as clothes.
