Method and apparatus for forming element-free spaces in slide fastener chain.

摘要

Discrete coupling elements (2) of a slide fastener chain (1) are removed using an apparatus comprising a pair of pressure pads (11), a punch (10), cutters (13), a pair of guides (14), and a die (16). To form element-free spaces (8) in the slide fastener chain (1), coupling elements (2) are removed by clamping the interengaged coupling elements (2) by the punch (10) and die (16), cutting one of the forked legs by the cutter (13), and removing the cut legs from both sides of the slide fastener chain (1).
