Abstract
A method for straightening sheet, strips, sections, girders, etc. The method includes measuring the straightening forces of at least one of the straightening rolls in a straightening machine and adjusting the positions of the straightening rolls in accordance with the measured values. The method further includes individually measuring the straightening force acting perpendicularly on the axes of rotation of the straightening rolls, and/or the roll bearings and/or the frame, and automatically readjusting the straightening rolls in dependence upon these measured values in a range of the occurring varying pressure forces.
