Abstract
A machine for straightening an elongated workpiece has a plurality of coacting tools which include first and second sets of tools arranged in alternate series along a fixed longitudinal axis to engage successive longitudinally spaced portions of a workpiece positioned therebetween with its longitudinal center line generally aligned with a longitudinal axis. A cam operated lever system simultaneously reciprocates the tools of the first and second sets in opposite transverse directions relative to the longitudinal axis and each other to alternately displace portions of the center line of the workpiece to one and the opposite side of the longitudinal axis. A mechanism is provided to vary the magnitude of reciprocating lever movement to vary center line displacement between a position of maximum displacement and a position wherein workpiece portions are substantially longitudinally aligned.
