ABSTRACT:
Method for orthogonal adjustment of straightened bars and an orthogonal adjustment unit located downstream of a bar straightening machine, 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. 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) by the orthogonal adjustment unit. The orthogonal adjustment unit includes at least one adjustment roll (13) which imparts deformation to the bar (14-114) by acting thereon radially in a desired position, within an angle of 360.degree., lying on a plane normal tothe nominal axis of the straightening machine working and having as its axis that nominal axis.
