ABSTRACT:
A cyclical wire stitching machine head includes a reciprocating staple-forming and driving apparatus which is coupled to a wire gripping and feeding mechanism which reciprocates with it. During each cycle of the machine the supply wire is gripped and a predetermined length thereof is fed through a cutter to a holder and severed while, simultaneously, the length severed in the preceding cycle is formed into a staple and driven through the work against a clincher. On the retraction stroke, the holder is rotated to bring the severed length of wire into position for forming and driving during the next drive stroke. A guide tube positively guides and supports the unstraightened wire from a supply coil along a feed path from the input end of the head to the gripping and feeding mechanism. Guide means are also provided for guiding the wire from the cutter to the holder while accommodating rotation of the severed length of wire with the holder.
