Abstract

A fastener stringer continuous manufacturing apparatus which eliminates a necessity of increasing a size of a manufacturing apparatus and is capable of chamfering attaching legs of an engaging element which is produced continuously from a metallic wire rod having a Y-shaped section, securely and accurately, without changing a load and stroke of a pressurizing hammer, the manufacturing apparatus comprises a pair of chamfering punches each of which is disposed above the pressurizing hammer at a height corresponding to a preceding engaging element implanted to a fastener tape in advance, the chamfering punch reciprocating with respect to a side face of the preceding engaging element and having a chamfering face which chamfers outer ridge portions of right and left legs of the preceding engaging element.

Description

Technical field [0001] The present invention relates to a method and equipment for continuously manufacturing a fastener stringer in which a plurality of engaging elements are implanted on one side of the fastener tape at predetermined intervals. Background technique [0002] As disclosed in, for example, Japanese Patent Publication No. 59-51813, this type of fastener chain is generally obtained as follows. That is, a long metal wire with a circular cross-section is molded into a transverse cross-section having a substantially Y-shaped shape by a plurality of rolls, and is sequentially cut with a predetermined thickness by a cutting punch and a cutting die to obtain each engaging element. The engaging head is formed into a mountain-like shape by a forming punch and a forming die, so as to obtain an engaging element including an engaging head and an additional leg (hereinafter referred to as a "wire engaging element"). Afterwards, the engaging elements are sequentially implanted o...
