A straightening apparatus for metallic bars, rods, wires, tubes and the like is provided which includes a rotor which is adapted for being rotated about a longitudinal axis thereof. At least three rollers are mounted to the rotor body and are clearly rotatable about their respective axis. A bar which is to be straightened passes along the axis of the rotor. The rollers are alternately disposed on either side of the rotor axis so as to sequentially engage the bar to be straightened. The rollers are mounted so as to be pivotal so that the plane of each roller can be pivoted with respect to a plane passing through the axis of the rotor. When the rotor is rotated, the bar to be straightened is urged along the axis of the rotor due to friction between the surface of the rollers and the surface of the bar. At the same time, the rollers straighten the bar. A flying cutter is preferably provided down stream of the bar straightening rotor, and furthermore, a cut bar collector is preferably provided for collecting bars cut by the flying cutter.
