ABSTRACT:
A pair of continuous slide fastener stringers are longitudinally fed by longitudinally reciprocable grip assemblies and driving rollers that is selectively actuatable. As the slide fastener stringers are advanced, one of the stringers is threaded through a slider held fixedly in its path of travel. The slide fastener stringers are cut off transversely across element-free gaps, and then the severed stringer pieces are moved forwardly until their leading end portions are positioned in a molding device, which molds a separable end stop on the leading end portions. The driving rollers are continuously driven to advance the slide fastener stringers until element-free gaps arrive at the cutter, whereupon the driving rollers are de-energized.
