A METHOD AND RELATED APPARATUS FOR FORMING AN ELEMENT-FREE GAP IN A CONTINUOUS SLIDING CLASP FASTENER STRINGER

摘要

A method and related apparatus for forming an element-free gap in a continuous slide fastener chain, which method is characterized by causing the interengaged parts of the fastener elements on the chain to pivot on themselves in a direction opposite to each other, with the results that the adjacent tapes edges are spread apart to expose therebetween said interengaged parts of the elements which are cut along a length corresponding to a desired gap to be formed.
