As shown in FIG. 1, FIG. 2, and FIG. 5, the monofilament guide 17 is disposed such that its axis is along the thickness direction of the needle bed 14, and is set to be the second from the end in the width direction of the needle bed 14. One end in the width direction between the needle 12 and the third needle 13 and the needle bed 14 Reciprocating motion is possible along the width direction of the needle bed 14. Further, the monofilaments 20 are sequentially fed from the openings of the front end portions of the monofilament guides 17. Further, the monofilament 20 is always fed from the monofilament guide 17 while the rack manufacturing device 10 is knitting the rack 30. Further, although the monofilament 20 of the present embodiment has a substantially circular cross section, the present invention is not limited thereto, and may have an elliptical cross section.

The reciprocating motion of the monofilament guide 17 is performed as shown in Figs. 5 to 8 at the time when the respective needles 11 are moved to the lowest position. Further, by the single reciprocation of the monofilament guide 17, the monofilament 20 is bent to form one of the fastener element portions 34 of the spiral fastener element row 33, and is knitted on the fastener cloth 31.

The head holding member 18 ensures the curved shape of the engaging head portion 35 of the monofilament 20 and the position of the engaging head portion 35, and is formed in an arm shape so as to be from the rear of the needle bed 14 (inside of FIG. 5) toward the upper side of the needle bed 14. Extended configuration. Further, the front end portion of the head holding member 18 is formed in a hook shape. Further, the head holding member 18 is provided to reciprocate up and down between the holding position of the predetermined portion to be formed of the engaging head portion 35 of the monofilament 20 from the upper end portion of the hook shape and the standby position at which the holding is released.

Further, in the present embodiment, when the head holding member 18 is at the standby position, the monofilament guide 17 moves in the direction approaching the head holding member 18, and when the head holding member 18 is in the holding position, the monofilament The guide 17 moves in a direction away from the head holding member 18.

Next, the operation of the rack manufacturing apparatus 10 of the present embodiment will be described with reference to Figs. 5 to 8 .

The side of the engaging head portion 35 is moved in the width direction of the needle bed 14, whereby the upper leg portion 36 of the fastener element portion 34 is formed.

Next, as shown in FIG. 6, the head holding member 18 is moved downward, whereby the predetermined portion to be formed of the engaging head portion 35 of the monofilament 20 is pressed from the upper end portion of the hook-shaped front end portion of the head holding member 18, thereby The formed predetermined portion of the engaging head portion 35 of the wire 20 is held. Further, the engaging head portion 35 of the fastener element portion 34 is formed by the hook-shaped front end portion of the head holding member 18 by the reverse movement of the subsequent monofilament guide 17.

Next, as shown in Fig. 7, in the state where the head holding member 18 is moved downward, the width direction movement of the monofilament guide 17 is reversed, and the engagement head of the monofilament guide 17 from the fastener element portion 34 is engaged. The portion 35 side faces the coupling portion 38 side and returns to the initial position, thereby forming the lower leg portion 37 of the fastener element portion 34.

Next, as shown in FIGS. 7 and 8, after the monofilament guide 17 is returned to the initial position, the needles 11 are moved upward and downward, and the knitting yarn guide 16 performs the pendulum motion and the yaw motion. The zipper cloth 31 is knitted, and one zipper element portion 34 formed by the action is woven to the zipper cloth 31. Then, the head holding member 18 is moved up to the standby position, thereby releasing the holding of the monofilament 20.

By the above-described series of operations, the following one-cycle operation is completed, that is, one linear fastener element portion 34 is formed while bending the linear monofilament 20, and is knitted on the fastener fabric 31 simultaneously with the knitting of the fastener fabric 31. Zipper element row 33. and, By repeating the series of actions, the one zipper element portion 34 is woven on the zipper cloth 31 each time a zipper element portion 34 is formed.

As described above, the rack manufacturing apparatus 10 according to the present embodiment includes a plurality of needles 11 arranged in parallel, and a substantially rectangular plate-shaped needle bed 14 having a plurality of needles 11 accommodated and slidably guided a plurality of knitting grooves 15 and a plurality of knitting yarn guides 16 for guiding the plurality of knitting yarns 41 to 43 respectively for the pitching motion and the yaw motion; and the substantially cylindrical monofilament guiding members 17 Arranged between the needle bed 14 and the knitting yarn guide 16 and on the side of the plurality of needles 11, the monofilaments 20 are sequentially fed out to form the fastener element row 33, and the sliding direction of the plurality of needles 11 and the zipper cloth 31 are knitted. The directions are parallel, and the monofilament guide 17 is disposed along the plate thickness direction of the needle bed 14 and along the needle bed between the predetermined needles 11 of the plurality of needles 11 and one end in the width direction of the needle bed 14. The width direction of 14 reciprocates. Therefore, the operation of the monofilament guide 17 becomes simpler than the operation of the monofilament carrier of the double needle bed type raschel apparatus. Therefore, the structure of the apparatus 10 can be simplified and the maintenance can be easily performed as compared with the double needle bed type Rachel apparatus.

Moreover, the rack manufacturing apparatus 10 according to the present embodiment includes the head holding member 18 that holds the monofilament 20 at the time of bending forming of the engaging head portion 35 of the fastener element portion 34, and the head holding member 18 is engaged with the head portion.
