In addition, the reed 13 reciprocates along the weaving direction between the waiting position on the warp supply side (the position shown in FIG. 2) and the beating-up position (the position of the two-dot chain line in FIG. 8). In addition, the reed 13 moves to the beating-up position and performs beating-up every time the weft Y2 is inserted and the fastener element E is formed (refer to FIG. 8), so that the weaving of the fastener tape T and the fastener element E The weaving is completed. The zipper element E is pushed by the reed 13 during beating-up, and is arranged into a prescribed shape.

As shown in Fig. 1, the weft thread guide 20 is a narrow plate-shaped or rod-shaped member 20 bent into a hook shape, and is attached to the first member M1 arranged on the first side S1. The weft thread guide 20 moves forward from the first side S1 to the second side S2 and returns from the second side S2 to the first side S1 by the rotation of the first member M1 about the first axis M1a.

In addition, as shown in FIGS. 2 and 4, a recess 20a for accommodating the weft Y2 is formed at the tip of the weft thread guide 20. The weft Y2 is supplied toward the supply path R from the first side S1. The weft thread guide 20 is located at a place where the weft thread Y2 is not in contact with the weft thread Y2 on the first side S1 before the movement from the first side S1 to the second side S2 is started. At this time, the weft Y2 is not hooked (not housed) in the recess 20a. And, as shown in FIG. 6, when the weft thread guide 20 moves from the first side S1 to the second side S2, it approaches the weft Y2 and pushes the weft Y2 to the second side S2. At this time, the weft Y2 is hooked (contained) ) In the recess 20a of the weft thread guide 20.

In addition, as shown in FIG. 5, instead of the recessed portion 20a, a thread through hole 20b through which the weft thread Y2 passes may be formed at the tip of the weft thread guide 20. In this case, the weft Y2 passes through the thread penetration hole 20b when the weft thread guide 20 is located on either side of the first side S1 and the second side S2. Then, when the reciprocating movement of the weft thread guide 20 is switched, the weft Y2 is caught by the knitting needle 12.

As shown in Fig. 1, the monofilament guide 30 is a rod-shaped member bent into a hook shape, and is attached to the second member M2 arranged on the second side S2. The monofilament thread guide 30 by the second The member M2 rotates centered on the second axis M2a, moves forward from the second side S2 to the first side S1, and moves back from the first side S1 to the second side S2.

In addition, as shown in FIGS. 2 and 3, a recessed portion 30 a for accommodating the monofilament MF is formed at the tip portion of the monofilament guide 30. The monofilament guide 30 is not in contact with the monofilament MF when it is located on the second side S2. That is, the monofilament MF is not hooked (not housed) in the recess 30a. And, as shown in FIG. 6, when the monofilament guide 30 moves from the second side S2 to the first side S1, it approaches the monofilament MF arranged in the supply path R and pushes the monofilament MF to the first side S1 . At this time, the monofilament MF is hooked (accommodated) in the recess 30a of the monofilament guide 30. Then, when the reciprocating movement of the monofilament guide 30 is switched, the monofilament MF is wound around the mandrel 11.

In the fastener stringer manufacturing device 10 configured in this way, as shown in FIGS. 6 and 8, the monofilament guide 30 is hooked at the first position P1 of the supply path R when moving forward to the first side S1. Hang the monofilament MF and move the monofilament MF to the second position P2 on the first side S1. When the monofilament guide 30 moves back to the second side S2, it separates from the monofilament MF at the first position P1 . That is, the monofilament thread guide 30 releases the hook of the monofilament MF. Therefore, by the reciprocating movement of the monofilament guide 30, the monofilament MF moves between the first position P1 located on the supply path R and the second position P2 located on the first side S1. Therefore, the monofilament MF swings by the distance D between the first position P1 and the second position P2. By this, the moving distance D of the monofilament MF can be shortened compared with the conventional device, and therefore, an excessive load is not applied to the monofilament MF. Therefore, in order to make the tension of the monofilament MF constant, a tension absorption mechanism is not required.

Also, the monofilament MF will not move to the second side S2 than the first position P1 Therefore, the monofilament MF will not be interwoven with the warp Y1 located on the second side S2 than the first position P1. Thereby, a plurality of warp threads Y1 are selected to be interwoven with the monofilament MF to fix the fastener element E to the fastener tape T to the fastener element fixing warp and the ground warp constituting the fastener tape T.

In addition, as shown in FIG. 7, when the weft thread guide 20 and the monofilament thread guide 30 are moved between the first side S1 and the second side S2, the warp yarn Y1 supplied from the upper side and the warp yarn Y1 supplied from the lower side Pass through the open shuttle L between the openings.

As described above, according to the fastener stringer manufacturing apparatus 10 of this embodiment, when the monofilament guide 30 moves from the second side S2 to the first side S1, it approaches the monofilament MF arranged in the supply path R, and The monofilament MF is pushed to the first side S1. At this time, the monofilament MF is hooked to the recess 30a of the monofilament guide 30, and therefore, the fastener stringer FS can be manufactured without applying an excessive load to the monofilament MF. In addition, since an excessive load is not applied to the monofilament MF, the tension absorbing mechanism can be eliminated.

In addition, according to the fastener stringer manufacturing apparatus 10 of the present embodiment, the monofilament MF does not move to a position closer to the second side S2 than the first position P1, and the monofilament MF does not move to a position closer to the second side S2 than the first position P1. The warp Y1 at the side S2 is interlaced. Thereby, a plurality of warp threads Y1 can be selected into the element fixing warp threads that are interwoven with the monofilament MF to fix the fastener element E to the fastener tape T and the ground warp threads constituting the fastener tape T.

In addition, as a modification of the present embodiment, as shown in FIG. 9, a hook (element forming member) 41 may be used instead of the mandrel 11. A protrusion 41a for winding the monofilament MF is formed at the tip of the hook 41. While the hook 41 moves from the position shown by the two-dot chain line in FIG. 9 to the position shown by the solid line, the monofilament MF is wound around the protrusion 41a And make the monofilament MF bend. Then, after the beating-up, in order to release the state where the monofilament MF is wound around the protrusion 41a, the hook 41 is retracted from the position shown by the solid line in FIG. 9 to the position shown by the two-dot chain line.

In addition, the present invention is not limited to the configuration exemplified in the above-mentioned embodiment, and can be appropriately changed within a range that does not deviate from the gist of the present invention.
