ABSTRACT:
An apparatus for folding and forming a continuous train of slide fastener coupling element bodies into a train of coupling elements includes a rotating forming disc against which the coupling element bodies are fed. The train is held on the forming disc for a portion of the disc rotation by a pair of flexible discs which clamp the leg portions of the bodies against the sides of the forming disc. After rotation through a portion of the forming disc circumference, the flexible discs are cammed outwardly and the train of coupling elements is pulled from the discs.
