  • Patent number: 5406692
    Abstract: This invention concerns an improvement in the wire reversing apparatus in the wire terminating equipment that fabricates terminal-attached wires of wiring harness. The turntable, which forms the wire into a loop by reversing one end of the wire fed out from the wire supply device, is provided at the underside with a gear secured to the rotating center thereof. A drive gear shaft that meshes with the gear of the turntable is shifted toward the wire feeding side so that the wire ends will not strike against the drive gear shaft to be bent when the wire is carried by a carrier chain in a direction perpendicular to the wire feeding direction.
