Abstract
A method and a machine for straightening sections by eliminating multi-axle deviations from the required section and from the required straightness using one or more straightening tools arranged, in series above and below the material to be straightened, on straightening axles which are parallel with one another. The adjustment of the straightening force and the adjustment of the horizontal inclination of the adjustable straightening axle are carried out hydraulically. The hydraulic system is configured so that a rapid change in position is possible either at the front and rear hydraulic cylinders or exclusively at the rear hydraulic cylinder in such a way that the straightening force and/or the horizontal inclination of the adjustable straightening axle can also be set during the straightening process.
