ABSTRACT:
Apparatus which repeatedly severs wire segments from a wire strand and conveys them for further processing comprises a pair of wire feed clamps which are reciprocably movable in opposite directions to feed the wire strand along a first path. The wire feed clamps are affixed to parallel flights of a pulley-supported steel cable which is axially driven back and forth by an oscillatably rotatable cable drum. The cable drum is oscillatably driven by a rack-and-pinion mechanism which includes a drive rod or rack bar reciprocably movable by an orbiting crank pin on a support member which is adjustably mounted on a motor-driven rotatable feed crank. A locking mechanism releasably locks the support member and its crank pin in selected positions relative to the feed crank. The crank pin orbit determines drive rod stroke, cable drum position and wire feed clamp spacing and travel. A feed clamp engaging mechanism engages a wire feed clamp to reposition both wire feed clamps, the cable, the cable drum, the drive rod and the crank pin support member and its crank pin relative to the feed crank to thereby change feed clamp spacing and travel. The locking mechanism unlocks to enable the drive rod to reposition the crank pin support member. An electronic system controls wire processing operations and repositioning operations.
