ABSTRACT:
A roll, particularly a back-up roll, for rolling flat material is composed of a rotating roll shell and a unit arranged within the roll shell for influencing the bending stiffness of the roll shell. The unit for influencing the bending stiffness of the roll shell is a friction bearing in the form of a body of rotation. The body of rotation can be adjusted by rotating the body. The body of rotation is shaped in such a way that the load application surface thereof corresponding to the zone of the roll shell to which load is applied is part of the circumferential surface of a rotation-symmetrical body and the edge of this circumferential surface is shaped in such a way that along the circumference of the body of rotation the width and/or position of the load application surface vary.
