1. A method of continuous production of twisted or stranded conductors including a plurality of wires along a machine line comprising the steps of supplying at a selected speed a plurality of strands that have been work hardened; inline annealing said strands; inline cooling the annealed strands following said annealing step to a predetermined temperature; inline stranding on a strander with the annealing and cooling steps for imparting at least one twist to the annealed and cooled strands; controlling the selected speed of the strands along the machine line for adjusting and controlling the selected speed of the strands moving along the line to be compatible with a take up speed for stranding, said steps being performed in succession without interruption to provide continuous operation.
