    Abstract: A bar straightening machine comprises a pair of rolls between which there is defined a path including two bends along which bar to be straightened is passed. The rolls are preferably of identical form, each comprising a first end portion of hyperbolic form, a second end portion also of hyperbolic form and an intermediate portion which merges smoothly with the end portions. The hyperbola from which one end portion is generated differs from the hyperbola from which the other end portion is generated, one end portion having a diameter somewhat greater than the corresponding diameter of the other end portion. The rolls are arranged with identical end portions remote from each other.
