ABSTRACT:
A lever at each end of a pressure roll has one arm connecting with means for applying a force thereto and another arm applying a bending moment through rotary bearings to the shell of a pressure roll. In one embodiment, the axle is non-rotating and is forked at the ends and mounted in a sliding carriage on stationary supports there, on which carriage a pressure and cylinder and piston are provided for carrying a force to a lever pivoted on a pin bridging the fork of the axle end to apply the bending moment to the roll shell through a rotary bearing. In another embodiment, the axle is rotary and connected at various places intermediate the roll ends by connection pieces past which bending moments may be transmitted and the lever is tubular and mounted on a stub of the axle by a swing bearing, and the bending moment is transferred to the shell by another swing bearing. Application of force to the lever for bending the roll shell in this case can be done manually with a set screw.
