Abstract

A machine (10) for straightening elongated workpieces (W) comprises at least three sets of coacting tools which include first and second sets (S1, S2) of tools arranged in alternate series along a fixed longitudinal axis (14) for engaging successive longitudinally spaced portions of a workpiece (W) positioned in the machine (10) with its longitudinal center line generally aligned with the longitudinal axis (14). Each set (S1, S2) of tools includes two transversely opposed tools (30) which have transversely spaced work engaging surfaces for engaging opposite sides of the workpiece (W). An operating means (16) is provided for simultaneously reciprocating the tools (30) of the first and second sets (S1, S2) relative to the axis (14) and in opposite direction relative to each other to alternately displace portions of the center line of the workpiece (W) to one and the opposite side of the longitudinal axis with a vibratory motion.
