  • Wire drawing machine with wire-relaxing roller
    Patent number: 4827752
    Abstract: An in-line wire drawing machine in which a roller with a one-way clutch allows wire to unwind from a rotatable drum while preventing the wire from slipping reversely on the drum. The roller is supported to float axially relative to the drum so as to track the natural course of the final wrap of wire and is spring-urged against the wire in all of its axial positions.

  • In-line wire drawing machine
    Patent number: 4099403
    Abstract: The drum of an in-line wire drawing machine is rotated by a mechanical variable speed drive whose speed is automatically adjusted by a speed trim control which senses the difference between the speed of the wire being supplied by the drum and the speed at which wire is being consumed by a using station. The final wrap of wire on the drum is engaged by a roller connected to a one-way clutch, the roller serving to prevent the wire from slipping on the drum and thus serving to increase the traction between the wire and the drum.
