ABSTRACT:
An installation for stretch-levelling strip metal, comprising, inside a stand, at least two bending units offset longitudinally and placed respectively above and below the strip carrying at least one work cylinder mounted rotatably about a transverse axis. The frame of at least one upper bending unit is mounted rotatably on two aligned journals about which the entire bending unit can rotate between a working position in which the work cylinder points downwards, and an inverted position in which the work cylinder points upwards and can thus easily be maintained or replaced.
