Abstract

A rolling device has an upper and a lower work roll and at least one upper and one lower backup roll. The work rolls and the backup rolls are supported on a common rolling mill stand. The work rolls can be adjusted relative to each other in order to adjust a specified rolling gap. Each of the work rolls is operatively connected to at least one bending device. At least one first bending device is paired with die upper work roll, and at least one second bending device is paired with the lower work roll. The second bending device comprises bending cylinders which are arranged in a vertically fixed manner. The upper work roll can be readjusted or carried by the first bending device, thereby vertically adjusting die height of the rolling gap. The first bending device comprises bending arms that interact with bending cylinders arranged in a stationary manner.
