ABSTRACT Method for orthogonal adjustment of straightened bars, whereby the bars may be of a rolled, drawn or extruded type or be obtained with a forming machine and may have any round, oval, square, rectangular or polygonal, etc. section and be solid or hollow, whereby a desired variable deformation opposed to the curved development determined by the last three staggered rolls (30-31-131) of a straightening assembly (11) is imparted to the bar (14-114) after the straightening and immediately downstream of the straightening assembly (11), the deformation imparted to the bar (14-114) acting thereon radially in a desired position, within an angle of 360°, lying on a plane normal to the nominal axis of the straightening machine working and having as its axis that nominal axis. Orthogonal adjustment unit located downstream of a bar straightening machine, wherein the bar may be of a rolled, drawn or extruded type or be obtained with a forming machine and may have any round, oval, square, rectangular or polygonal, etc. section and be solid or hollow, the orthogonal adjustment unit (10) being located immediately downstream of a straightening assembly (11) and between the straightening assembly (11) and the contrast unit (12),the orthogonal adjustment unit comprising at least one adjustment roll (13) capable of idling and of being positioned as required within an angle of 360° on a plane normal to the nominal axis of the straightening machine and having that nominal axis as its axis, the adjustment roll (13) being in contrast with the last outlet roll (131) of the straightening assembly (11), the contrast unit (12) and straightening assembly (11) lying substantially on the same plane parallel to or coinciding with the plane on which the adjustment roll (13) lies.
