ABSTRACT:
A levelling machine, particularly for levelling sheet steel and strip steel, includes upper and lower levellerg rolls arranged offset relative to each other. The leveller rolls are supported by back-up rolls arranged in roll stands and supported in crossbeams. The back-up rolls support the leveller rolls over the length thereof. At least the upper crossbeam is adjustable by adjusting cylinders for positioning the leveller rolls. The upper roll stand and the upper crossbeam are mounted so as to be tiltable in travel direction of the material being levelled, so that compensating cylinders arranged between the roll stand and the crossbeam facilitate pivoted positions. The tilting points of the upper roll stand and of the upper crossbeam are arranged in several planes located one above the other.
