Controlled deflection roll

摘要

A controlled deflection roll comprising a tubular-shaped flexible roll shell rotatable about a fixed support. The roll shell is supported by pressure elements arranged in a pressure plane. The pressure elements are movable relative to the fixed support in such pressure plane and serve to exert a pressure force. The roll shell is fixedly retained at its ends to preclude movement perpendicular to the pressure plane. At least one device for influencing laterial deformation of the roll shell is arranged at the support. Such device is equipped with at least one impact or contact surface and cooperates with the inner surface of the roll shell.
