The forces exerted by actuators are detected and devices are provided, which use those detected forces to regulate a pressure force exerted by one cylinder against another cylinder in a printing machine. The several forces can also be used for placing or removing one cylinder with respect to another cylinder. One cylinder may be mounted in a cylinder holder which is, in turn, mounted in a frame holder. At least two actuators are arranged between the cylinder holder and the frame holder. These actuators exert a radially directed force against the cylinder holder when they are actuated by a control signal.
