Abstract
A cylinder for a printing press is adjusted away from a printing stock web or an adjacent cylinder by rotation of an eccentric element. The change in position caused by the movement of the eccentric element is compensated by an additional rotating movement superposed on the rotating movement of the cylinder such that the outer surface of the cylinder has no relative velocity relative to the adjacent cylinder or the printing stock web. Compensation is carried out by a regulating circuit to which is supplied the actual rotational angle of the cylinder with respect to the eccentric element and the actual rotational angle of the eccentric element with respect to the side wall or an angular function derived therefrom.
