ABSTRACT:
The specification discloses a self-compensating die in which a plurality of roller sets mounted in a rotating rotor rotate about a wire passing through the rotor and compressively engage the wire to thereby reduce its diameter. A sleeve rotatable with the rotor but axially slidable with respect thereto includes cams which control the roller sets in response to adjusting signals from a control system to thereby automatically compensate the roller pressure applied in response to roller wear and other errors, and to thereby provide a means for adjusting the die for production of different sized wires from a wire of a given starting diameter.
