Abstract
An apparatus and method for continuous operation for the production of conductors that include twisted or stranded wires or filaments includes supply payoff for providing a plurality of strands that have been work hardened. The wires or strands are annealed in line with the payoff and subsequently cooled by a chiller in line with the annealer for cooling the annealed strands output from the annealer to a predetermined temperature. A dancer between the supply payoff and the annealer ensures the speed at the output of the payoff is matched to the intake speed of the annealer. A strander in line with the annealer and cooler or chiller is provided for imparting at least one twist to the annealed and cooled strands. Speed control, for example an additional dancer, is provided in line between the cooler and the strander for adjusting and controlling the speed or velocity of the strands moving along the line to maintain a speed compatible with the take up speed of the strander. The predetermined temperature is selected to be the ambient operating temperature of the strander for copper or aluminum cable.
