A method and an apparatus for simultaneously performing fixing and manufacturing have not been proposed yet.

[Problems to be Solved by the Invention] The present invention is directed to woven fastener tapes, molding dentition,
An object of the present invention is to provide a method and a device for manufacturing a hidden woven slide fastener stringer by simultaneously performing weaving and fixing at a high speed.

[Means for Solving the Problems] The invention according to claim 1 provides a synthetic resin monofilament for forming a coupling tooth into a tape warp group for fastener tape woven and a mounting warp group for mounting a coupling tooth. On the other hand, the fastener tape is supplied from the outside of the attached warp yarn group and is formed into a helical coupling tooth in the vicinity of the cloth fell while the fabric structure of the warp yarn group and the weft yarns wefted into the warp group is used. At the same time as weaving, weaving a dentition row on one side edge of the fastener tape,
In the method of manufacturing a fastener stringer to be fixed,
The synthetic resin monofilament is engaged with a hook arranged on one side of the attachment warp thread group closer to the tape warp thread group from the outside of the attachment warp thread attachment thread for guiding to the cloth fell by beating. , The meshing head faces the tape warp group side, and the upper and lower legs are formed into coupling teeth existing in the mounting warp group, and by the mounting warp group and the weft, the meshing head is formed on one side edge of the fastener tape. The structure is such that the dentition row is woven and fixed so that it faces the center of the fastener tape.

In order to carry out the above-mentioned method, the invention according to claim 2 provides a front lead for guiding a tape warp group for weaving a fastener tape and a mounting warp group for attaching a coupling tooth, and a front lead arranged in the mounting warp. And a coupling tooth forming plate that operates in the same direction as the front lead, and a hook for forming a coupling tooth that has a free end facing the weave in the side portion of the mounting warp group near the tape warp group, On the outer side of the attachment warp thread group for attaching the engagement tooth, a first carrier for inserting a weft into the tape warp thread group and the attachment warp thread group, and a synthetic resin monofilament for forming the engagement tooth are located outside the attachment warp thread group. To a position engaging with the hook, a second carrier that performs a reciprocating motion is arranged.

[Operation] According to the method of claim 1, the synthetic resin monofilament engaged with the hooks in the area adjacent to the tape warp group and the attached warp group has the engagement head in the posture of facing the tape warp side. At least the upper and lower legs are woven in a woven structure in which the attachment warp yarns and the weft yarns are interwoven, and the weft yarns are interlocked with the tape warp yarns to form a fastener tape, thereby being fixed on one side of the fastener tape. Therefore, when the other side of the fastener tape is folded back toward the coupling inversion portion side of the coupling tooth row and heat-set, it is sewn to the adherend in that state to form a hidden woven slide fastener stringer.

According to the device of claim 2, the synthetic resin monofilament engaged with the hook for forming the coupling tooth by the second carrier is wound around the hook in a coil shape by the reciprocating motion of the second carrier. Therefore, if the meshing head preformed on the monofilament is set in advance so that the winding position of the monofilament faces the tape warp side,
After that, it is continuously and accurately formed into the dentition on the coil.
At the forming position, the meshing head faces the tape warp group side, and the upper and lower legs thereof are present in the attached warp group.

After forming with hooks, the engaging teeth formed with the engaging tooth forming plate that operates in the same direction as the front lead are pressed against the cloth fell, and the upper and lower legs occupy accurate positions, at which position the warp and the weft are attached. Interwoven and fixed.

Since the first carrier for inserting the weft and the second carrier for engaging the synthetic resin monofilament with the hook for forming the coupling tooth are arranged outside the attached warp group, they interfere with the opening movement of the warp group. In addition, since the continuous synthetic resin monofilament is introduced from the outer side of the attached warp group to be engaged with the hook for forming the coupling tooth, the continuous synthetic resin monofilament before molding is of the warp group. It does not hinder the opening movement.
