Abstract: Apparatus for making electrical harnesses including wires and electrical connectors, the apparatus comprising a wire feed path extending and substantially horizontally and axially of the apparatus; a connector attaching device comprising a cooperating assembling punch and die pair disposed on respective sides of the wire feed path, and a wire cutting blade located adjacent to the punch and die pair; a connector supplying device for supplying the connectors to the assembling die; a first chuck reciprocally movable along the wire feed path for pulling out the wires in its advancing movement for a distance corresponding to a desired length of the electrical harness; a second chuck for holding the supplied wires laterally at equal intervals, and guiding the same to the connector attaching device along the wire feed path, the second chuck reciprocally movable in a small range during which movement to align the top ends of the wires; an insulation covering stripping device mounted on the second chuck; whereby, upon

Abstract: An insulation covering stripping device for use in combination with automatic apparatus for manufacturing electrical harnesses, the device being included in a moving chuck for pulling out the insulation clad wires to a desired length so that the insulation covering stripping is carried out as the same time as when the lengths of the wires are measured, thereby shortening the operation time of manufacturing electrical harnesses.
