Abstract

In a method for compensating the bending of the crossbeams of a straightening (levelling) machine for sheets and strips with upper and lower straightening (levelling) rolls which are arranged offset relative to one another and are supported along their length by means of back-up rollers supported, for their part, against crossbeams and arranged in roller frames, in which arrangement at least the upper crossbeam can be adjusted in order to position the levelling rolls, operation is improved and, in particular, a constant levelling gap achieved if the levelling gap is regulated under load. In a levelling machine (1), outer fixed stops (25) and, spaced apart between the fixed stops (25), plungers (26) are arranged at the bottom and top at the entry and the exit sides between the roller frames (6 and 7) and the respective crossbeams (4 and 5) and symmetrically with respect to the machine centre (24). Each of these plungers is connected to a control valve (27) and all of these control valves are connected to a computer (28) which supplies them with control signals. <IMAGE>
