  • Patent number: 3939552
    Abstract: A method and apparatus for feeding a pair of wires in which the length of the fed wires may be varied relative to each other and also in which accurate positioning of the wires at the receiving station is accomplished. At the start of a cycle of operation the leading end portions of a pair of supply wires are engaged by wire clamp means immediately adjacent a wire support. The wire clamp means is then moved to an extended position to feed the leading end portions away from the wire support, and as the wire clamp means is being moved to its extended position a bight is formed in one of the wires to vary its length relative to the other wire. A trailing portion of the pair of wires is now cut and the insulation is stripped from the trailing end portions of the cut wires as well as the new leading end portions of the pair of supply wires.
