Abstract: A wire feed mechanism alternately feeds a pair of parallel wire strands A and B through spaced-apart turret jaws on a rotatable turret, through a cutter-stripper head, through a wire gathering device and through spaced-apart conveyor clamps in a conveyor. When a desired length of first wire strand A is fed, a first conveyor clamp closes on strand A and the cutter-stripper head severes a wire segment 12A from strand A and strips the newly-severed ends of strand A and wire segment 12A.
