ABSTRACT:
An apparatus for twisting two or more electrical conductors into a single cable, each of the conductors having a portion of their insulation stripped at each end. Wires of a desired length are cut and stripped and fed through a twist die having a belled entry to a point where the wires are gripped in a nip formed between a pinch roll and a power roll. These rolls are mounted so as to be swung about the longitudinal axis of the wires so as to twist the wires together into a single cable. A manifold and air supply system is provided so as to prevent lateral swinging of the twisted cable as it passes from the rollers to a wire guide from which the completed cable is dropped into a wire tray.
