Abstract From the Canadian patent

6409 INVENTORS: MARIO BIONDETTI and IGNAZIO MARCHIORO CAN, INVENTION: CONTROLLED DEFLECTION ROLL ABSTRACT OF THE DISCLOSURE, A controlled deflection roll comprising a stationary roll support and a roll shell rotatable about such roll support. The roll shell is guided with the aid, of guide elements, relative to the roll support in the pressure plane of the controlled deflection roll in order to generate lift-off movements. Lift-off pistons are guided in the roll support and bear against inner surfaces of the guide elements. Each of the lift-off pistons can be arranged within guide means of the related guide element such guide, means being bounded by essentially parallel guide surfaces.
