Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be specifically described based on the drawings.

[0035] The illustrated embodiment is a shaped implant applying the present invention to an engaging element for a slide fastener. Of course, the present invention is not limited to the shaping implantation device, and can also be applied to, for example, an engaging element forming device that does not implant the engaging elements formed one by one into a fastener tape, but is temporarily recovered, or is applied to a device having a forming mechanism other than the above-mentioned devices. , All devices in which engaging elements are formed from metal wire.

[0036] figure 1 It is a perspective view of the continuous manufacturing apparatus of the fastener stringer of the present invention, and the cutting die 1 arranged on the not-shown hammer is supported so as to be freely reciprocable in the directions of arrows c and d via a not-shown guide mechani...

Abstract

The invention provides an engaging element forming device for a zipper and an engaging element for the zipper. The engaging element forming device comprises a cutting die, a forming die, a cutting punch slidingly arranged on the upper surface of the cutting die in a contact manner, and a forming punch which is coordinated with the forming die to lift, wherein the cutting punch comprises a main body provided with a first cutter part coordinated with the cutter part of the cutting die at the top end to cut a wire rod for the engaging element. A sliding part which slides relative to the cutting die is arranged on the surface, relative to the cutting die, of the main body in an extending manner from the main body. The sliding part is provided with a second cutter part which protrudes forwards along the sliding direction of the cutting die for forming a concave part on a part of the wire rod for the engaging element. The first cutter part is provided with a first cutter face which is consistent with a part, which forms a head of the engaging element, of the wire rod for the engaging element in shape. The second cutter part is provided with a second cutter face which has a flat inclined face formed in a manner of enabling the protruding cutter to become shorter from top to bottom in length.

Description

technical field [0001] The present invention relates to an engaging element for a slide fastener and an engaging element forming device that are continuously formed by cutting an engaging element wire having a substantially Y-shaped cross section in a cross-sectional direction perpendicular to the longitudinal direction of the engaging element wire. More specifically, The present invention relates to an engaging element and an engaging element forming device for a slide fastener in which an inclined surface is formed at the front end of a surface of an engaging head on which an engaging recess is formed. Background technique [0002] As a method of manufacturing an engaging element for a so-called two-way slide fastener that can be opened and closed in either direction, the following method is known: while intermittently supplying a metal wire having a substantially Y-shaped cross section, using a cutting punch and The cutting die sequentially cuts off an engaging element th...
