ABSTRACT:
An apparatus for cutting off lengths of slide fasteners from a continuous chain thereof includes a cutting punch coactive with an anvil, there being feed rolls disposed in the path of movement of the fastener chain upstream from the cutting punch, and a pair of delivery rolls in such path downstream of the cutting punch. The upper delivery roll is arranged to reciprocate with the cutting punch and to engage the chain before the cutting punch does, and to continue to engage the chain until the cutting punch has been slightly retracted. Such retraction of the delivery roll facilitates feeding of the chain even though the leading end may be slightly curled.
