ABSTRACT:
An improved apparatus for finishing slide fasteners by cutting off an elongate slide fastener chain across longitudinally spaced element-free spaces is provided wherein a slider arresting mechanism is disposed between a cutting mechanism and a feed mechanism and movable into and out of a path of travel of the slide fastener chain for temporarily arresting a slide fastener against downstream movement while the slide fastener chain is being fed by the feed mechanism, and a detecting mechanism is operatively connected with the slider arresting mechanism for detecting the engagement between an end stop and the slider which occurs when the slide fastener chain is fed by the feed mechanism while the slider is being arrested by the slider arresting mechanism. The detecting mechanism is operative, upon detection of the engagement between the end stop and the slider, to stop the operation of the feed mechanism to terminate the feed of the slide fastener chain and activate the cutting mechanism to perform its cutting operation.
