In performing operations on a continuous slide fastener chain at spaced locations therealong, the slide fastener chain is incrementally advanced to successively advance the spaced locations to an operating station. The chain is advanced from a reel which is braked only when a loop of maximum size is sensed in a loop forming mechanism. Tension is relieved in the slide fastener stringer by means of a continuously rotating capstan which will grip the slide fastener stringer to advance the chain and overcome inertia of the reel.
