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.

Abstract: Movable shears and a method for the automatic or non-automatic bending of the trailing end of bars in bending-shaping machines having a bending assembly located downstream of a shears (24) and of a bar feeder unit are disclosed. The bars may be already straightened or already straightened and sheared to size or may require straightening and the bar (29), after the required bends have been applied to its leading end (T), is fed forwards with a movement of distancing of its leading end (T) by an appreciable length at least partly by the feeder unit. When this forward length of feed has been completed, the bar (29) is sheared by the shears (24), thus creating a trailing end (C) of the residual bar (129). The movable shears (24) are able to slide on a longitudinal slide block (45) which is positioned as required in a direction lengthwise to the bar (29) so as to determine the length of the trailing end (C) of the residual bar (129) in relation to the bending assembly (35).
