ABSTRACT:
In a method of and an apparatus for processing a pair of continuous slide fastener stringers having element-free spaces between a plurality of longitudinally spaced chains of partly interengaged coupling elements with sliders mounted respectively thereon, the stringers are fed downwardly in a vertical direction at a low speed by an upper roller feed unit until their leading ends are sensed, whereupon they are fed at a high speed by a lower roller feed unit. The coupling element chains are fully closed one by one by the respective sliders which are releasably held by a slider holder disposed between the feed units while the stringers are fed at the high speed. The stringers are stopped by a chain stopper having means insertable in the element-free space in response to the full closure of the coupling element chain, and are severed across the element-free spaces by a cutter disposed between the slider holder and the lower roller feed unit, the severed chains being automatically neatly stacked on a chute in juxtaposition to each other.
