Abstract: In a cylinder arrangement for a rotary printing press, the backlashes caused by traction of the drive gears must be compensated for. This is accomplished by using a cylinder that is able to compensate for the backlash and positioning the cylinder at a determinable rotational angle differential with respect to another cylinder in the cylinder arrangement.

Abstract: A method and an apparatus for axially positioning a flexible plate on a surface of a cylinder, that is divided into several axially spaced segments, utilizes a plate transport arrangement to transfer plates from a plate preparation device to the plate cylinder. The plate is axially shiftable during transport and arrives at the plate cylinder in proper axial position.

Abstract: A device for mounting, removing and transporting an easily bendable device, such as a printing plate, to and from a plate cylinder includes a printing plate preparation device which supports the plate, and a cross arm with a plate gripper and pressing assembly. A gripper portion of the plate gripper and pressing assembly acts on the plate and is movable toward and away from a suspension strip of a cylinder. The plate gripper and pressing assembly can be moved to a parked position where it is out of the way and is shielded from contaminants.

Abstract: A rotatable tool head for a machine tool includes a tool slide and a mass balancing counter slide which are radially displaceable in opposite directions. The counter slide is mounted in a central recess of the tool slide such that the mass centers of the tool slide and the counter slide move along substantially the same radial line during tool adjustments. In this manner unbalanced masses present in an arrangement where the slides are positioned in axial or radial adjacent relationship, are substantial eliminated.

Abstract: It is known that every single or multi-phase power consumer such as a motor is optimally designed only for a certain power take up. Other power take ups deviating from this value result in a decreased ratio between power output and current intake. The circuit arrangement described in this application facilitates a fully automatic regulation and thus immediate adjustment of the respective power consumption to the respective power demand so that a motor or similar power consumers can be operated under energetically optimum conditions even under partial load. As a function hereof an advantageous phase detection facilitates generation of a regulated voltage with the current intake being reduced with increasing phase shift resulting in an increase of the output factor. For this purpose a Triac in series with the power consumer in the network is triggered in a certain manner in multiplex operation and a circuit differentiation is made among several phase controls.
