ABSTRACT:
A bending device for a rolling mill having four-high or multi-roll stands having working rolls with bearing chucks, support rolls and, as applicable, intermediate rolls arranged between the working rolls and the support rolls. First bending blocks that act bilaterally on each bearing chuck of the working rolls are run vertically in windows of the roll stand. Vertically opposite of the first bending blocks of each working roll pair are movable toward and away from each other via first piston-cylinder units. A second vertically movable bending block is movable independently of the first bending blocks via a second piston-cylinder unit supported on the roll stand so that the second bending block thereby acts bilaterally on each bearing chuck
