ABSTRACT:
In straightening steel sections, a machine is used having straightening rollers and pressing rollers each formed with a contact surface and arranged oppositely on vertical line of the straightening rollers. The cross-section of the steel section to be straightened is held between the contact surfaces of the rollers, and the pressing rollers are displaceable in the reduction direction as well as in the axial direction to adjust the amount of displacement.
