ABSTRACT:
A rotary power transfer component incorporated in the rotary to reciprocating motion conversion drive mechanism which operates the reciprocating feeder of a multiple slide machine increases the time available to the forming operation by correspondingly decreasing the feed time of the wire or ribbon stock during each cycle. The rotary power transfer component comprises a drive wheel and crank wheel mounted for respective eccentric rotation. The drive wheel, which is driven at a uniform rate of rotation synchronized to the forming operation of the machine, has an eccentric fixed pin which engages a radial slot in the crank wheel to thereby impart to the latter a synchronized cycle with varying speed of rotation within the cycle to be converted to a rapid advance feed stroke and a slow return stroke for the reciprocating drive of the feeder during which return stroke the forming operations are performed.
