Abstract
An apparatus and method of continuously drawing and annealing wire in a slip mode. The method comprises the steps of directing a wire successively through a plurality of drawing dies of a continuous wire drawing machine, and from the next to the last die of the machine continuously directing the wire to and through apparatus for annealing the wire. From the annealing apparatus the wire is continuously returned to the machine for a final drawing operation. Before the wire is returned to the machine, however, the temperature of the wire is controlled to provide the wire with metallurgical properties suitable for further processing, such as the final drawing operation.
