ABSTRACT:
In a controlled deflection roll comprising a roll shell rotatable about a stationary support and braced or supported by support elements at the stationary support, a rotational moment is intentionally exerted at the opposite ends of the roll shell by force-exerting elements. These force-exerting elements extend in axial direction of the controlled deflection roll but are offset in spaced relation with respect to the lengthwise axis of the controlled deflection roll. These force-exerting elements operate in pairs in opposite directions with respect to one another. A lever arm is formed by the distance or spacing between the force-exerting elements and such lever arm exerts a greater rotational moment in the presence of modest space requirements and without deformation of the roll shell.
