ABSTRACT:
A roll stand has upper and lower rotatable working rolls defining a nip that pinches a workpiece strip and upper and lower vertically spaced rotatable backing rolls vertically flanking and engaging the working rolls. A drive includes a motor, upper and lower backing-roll outputs drivable by the motor, and upper and lower working-roll outputs also drivable by the motor. Respective upper and lower backing-roll and working-roll releasable connections are provided between the outputs and the respective rolls. When the working rolls are of large diameter, the backing-roll connections are released to disconnect the backing rolls from the drive and the working-roll connections are engaged to connect the working rolls to the drive and, when the working rolls are of small diameter, the working-roll connections are released to disconnect the working rolls from the drive and the backing-roll connections are engaged to connect the backing rolls to the drive.
