Abstract: A color deck of a printing machine is usable to ink a printing cylinder. A roller nip is formed by at least one friction cylinder that is driven by a drive motor for rotary movement. A freewheel clutch is situated between the first friction cylinder and the drive motor for that first friction cylinder.

Abstract: Printing groups are each comprised of at least two cooperating cylinders, each of which is mounted in a bearing unit that radially displaces its associated cylinder. At least one of these bearing units is provided with an actuator which is controlled, or regulated by a control unit. An inking unit, which encompasses at least one ink application roller, is provided for each printing group. At least one of the cylinders of the printing group, and an ink application roller of the associated inking unit can optionally be placed against each other. A dampening unit, comprising at least one dampening fluid application roller, is also provided. At least one of the cylinders of the printing group and a dampening fluid application roller of the dampening unit are also optionally placed against each other. The at least one actuator for the bearing unit is remotely controlled and is embodied either as a hydraulic actuator or as a pneumatic actuator.

Abstract: Printing units are supported between side frames of a web-fed rotary printing press. Each such printing unit includes at least one transfer cylinder and at least one cooperating printing cylinder, which is embodied as a form cylinder. These cylinders are rotatably mounted between the spaced side frames. The printing unit is provided with an inking unit that includes a roller.

Abstract: An inking system of a printing press is utilized for inking a printing cylinder. The inking system is configured as a long roller inking system and includes two distributing cylinders that are disposed serially in a roller train. A first one of these distributing cylinders is mounted, in the roller train, close to the printing cylinder. The other of these distributing cylinders is mounted, again in the roller train, further away from the printing cylinder. The printing cylinder is rotationally force-driven by an angle position controlled drive motor. One of the two distributing cylinders of the inking system is rotationally force-driven by a drive motor that is mechanically independent of the drive for the printing cylinder. The other one of the two distributing cylinders is rotationally driven by frictional engagement with adjacent rollers or cylinders.

Abstract: Printing units are supported between side frames of a web-fed rotary printing press. Each such printing unit includes at least one transfer cylinder and at least one cooperating printing cylinder, which is embodied as a forme cylinder. These cylinders are rotatably mounted between the spaced side frames. The printing unit is provided with an inking unit that includes a roller.

Abstract: The tension of a web in a rotary printing press is regulated during passage of the web between at least first and second cylinders of at least one printing group. The two cylinders are driven using at least one drive mechanism. A distance between the two cylinders is varied to influence the web tension before, between and after the printing groups.

Abstract: A print unit of an offset printing machine utilizes individually driven cylinders. Each forme cylinder or plate cylinder is driven by its own, separate drive motor. The blanket cylinders, or cooperating blanket cylinders and counter-pressure cylinders are driven together by associated drive motors.
