ABSTRACT:
A roll stand with roll rings which are placed from one side or in a cantilivered manner on a pair of adjustable roll support shafts which are supported on two sides. Both roll support shafts have extension journals which project beyond the roll rings. Journal bearings can be slid onto and are fixable on the extension journals. The journal bearings have bearings housing which are connected with each other in a frictional engaging manner for absorbing rolling forces by means of piston-cylinder units which can be actuated by a pressure medium and are movable parallel to the direction of adjustment of the roll support shafts. On of the bearing housing is connected to the piston rods of the piston-cylinder unit and the other bearing housing, which supports the piston-cylinder units, sliding guide means for the piston rods. The roll stand further includes additional piston rods. The roll stand further includes additional piston-cylinder usits arranged between the two bearing housings. the cylinders and pistons of the additional piston-cylinder units are guided by the piston rods of the other piston-cylinder units which connect the bearing housings. The pistons of the second piston-cylinder units rest against one of the two bearing housings and the cylinders of the additional piston cylinder units rest against the other of the bearing housing. Pressure can be applied to the additional piston-cylinder units independently of the other piston-cylinder units.
