Belt T (refer to Figure 22).

Further, as the first hammer 21 advances, the guided surfaces 62b of the left and right chamfered punches 62 are in contact with the guide surfaces 73a of the left and right chamfered punch guides 73, and the left and right chamfered punches 62 are widened. Moving forward inward, the chamfered portion 62a of the chamfering punch 62 is used to chamfer the corner of the fastener element Eb attached to the fastener tape T immediately before the fastener element Ea currently attached to the fastener tape T (see Figure 23).

Next, the operation of the fastener stringer manufacturing apparatus 10 will be described with reference to FIGS. 17 to 23.

First, FIG. 17 shows a state in which the fastener element E is attached to the fastener tape T in a state where the first hammer 21 is advanced. At this time, the wire supply unit 100 supplies the wire W to the insertion hole 22 a of the cutting die 22 to a thickness corresponding to the thickness of the fastener element E, and the wire W is formed on the cutting die 22 in a manner corresponding to the fastener element E. The degree of thickness is outstanding.

Next, as shown in FIG. 18, the first hammer 21 is retracted, and the wire W sandwiched between the insertion hole 22a of the cutting die 22 and the cutting recess 23a of the cutting punch 23 is cut into A fastener element E of a predetermined thickness. Then, the first hammer 21 is further retracted, the engaging head E1 of the fastener element E is fitted into the forming recess 43 a of the forming die 43, and a pair of leg portions E2 of the fastener element E are fitted into the pressing parts, respectively. The left and right pressing portions 61 a of the pressing portion 61 press the recessed portions 61 a of the punch 61. As a result, the fastener element E is in a state of being fitted and held in the forming recessed portion 43 a of the forming die 43 and the recessed portions 61 a of the right and left pressing punches 61. Then, at this time, the fastener tape T is conveyed upward by the tape supply unit 110 to a thickness corresponding to two fastener elements E.

Next, as shown in FIGS. 19 and 20, by the second hammer 41 moving downward, the element pressing pad 44 presses a pair of legs E2 of the fastener element E downward, and forms a punch 42. The engagement head E1 of the fastener element E is punched, and the engagement protrusion E3 and the engagement recess E4 are formed in the engagement head E1 of the fastener element E. In addition, the engaging convex portion E3 is formed by the forming concave portion 43 a of the forming die 43, and the engaging concave portion E4 is formed by the front end portion of the forming punch 42. Then, the second ram 41 moves quickly upward after the engagement head E1 is formed.

Next, as shown in FIG. 21 and FIG. 22, the first hammer 21 advances, and the fastener element E moves to one edge portion of the fastener tape T, and one side of the fastener tape T is inserted between the pair of legs E2. The edge portion, and the left and right pressing punches 61 that advance inward in the width direction of the pressing portion 60 press the pair of leg portions E2 toward the fastener tape T side, respectively, and attach the fastener element E to the fastener tape T Side edge.

Moreover, at this time, as shown in FIG. 23, the left and right chamfering punches 62 advance inward in the width direction together with the left and right pressing punches 61. Therefore, the chamfering portion 62a of the chamfering punch 62 is currently installed on the side. The corner of the fastener element Eb of the fastener tape T before the fastener element Ea of the fastener tape T is chamfered. Thereafter, by repeating the above-mentioned operation, the fastener element E is continuously attached to one edge portion of the fastener tape T.

As described above, according to the fastener stringer manufacturing apparatus 10 of this embodiment, the forming die 43 is integrally formed in the die body 28 of the cutting die 22, so that the number of parts can be reduced, thereby reducing manufacturing costs.

Furthermore, in the conventional fastener chain belt manufacturing device described above, the vertical alignment (height direction) of the spacer and the mold body is manually aligned. Therefore, it is necessary to stop the operation of the device for a long time when the mold body is replaced, and the device operation Reduced efficiency. However, in the present invention, the forming die 43 is integrally formed on the die body 28, and the die body 28 is positioned on the base portion 26a of the spacer fixing member 26 to position the die body 28 in the vertical direction. The position alignment operation exists. Therefore, it is not necessary to stop the operation of the device for a long time for the replacement of parts, so that the operation efficiency of the device can be improved.

Furthermore, according to the fastener stringer manufacturing apparatus 10 of the present embodiment, a fitting recessed portion 25 a is formed in the front end portion of the die holder 25 in a vertical direction by fitting the cutting die 22 in the left-right direction of the cutting die 22. Therefore, when installing the spacer 27 and the mold body 28, it is not necessary to manually position the spacer 27 and the mold body 28 in the left-right direction. Therefore, it is not necessary to stop the operation of the device for a long time for the replacement of parts, so that the operation efficiency of the device can be improved.

Furthermore, according to the fastener stringer manufacturing apparatus 10 of the present embodiment, an insert is formed on the rear surface of the spacer 27 in the left-right direction to position the spacer 27 in the vertical direction by fitting to the front end portion of the die holder 25. Since the recessed portion 27 b is fitted, it is not necessary to manually position the spacer 27 in the vertical direction when mounting the spacer 27. Therefore, it is not necessary to stop the operation of the device for a long time for the replacement of parts, so that the operation efficiency of the device can be improved.

In addition, the present invention is not limited to the contents exemplified in the embodiment, and can be appropriately modified without departing from the gist of the present invention. For example, a lightening member may be appropriately provided in the spacer of the cutting mold and the mold body.

Further, as a modification of the mold body 28, as shown in FIG. 25, there may be no communication hole 28c for communicating the two intersecting cutting grooves 28a and the two intersecting suction holes 28b. In this case, chips and the like generated when the wire W is cut are not sucked into the cutting groove 28 a but are sucked into only the suction hole 28 b.
