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.
