The printing unit (16; 17), which is embodied as a nine-cylinder satellite printing unit (16; 17), is equipped with four plate cylinders (07) and a counterpressure cylinder (18) that is configured as a satellite cylinder (18). At least one inking roller of an inking group (09) is disposed so as to cooperate directly with the plate cylinder (07). One respective plate replacing mechanism (11; 11a; 11b), which encompasses a front section facing the associated plate cylinder (07), is assigned to at least two plate cylinders (07) that are placed next to each other in a horizontal direction.

Abstract: A printing unit, which is a part of a multi-color printing press, has a plurality of double printing units which are arranged vertically one above the other and consist of two printing groups forming a double print position. The printing group cylinders are mounted together in a central stand section. Inking units, which are associated with the printing groups, are mounted in outer stand sections. A distance between adjacent ones of these stand sections is adjustable. Printing and transfer cylinders of each printing group are coupled by a toothed gear wheel connection and are driven in pairs by a separate drive motor. The toothed gear wheels of all of the printing group cylinders are arranged in a common lubricant chamber which is formed by the central stand section and a cover. The inking systems have at least one separate drive motor, which is independent of the printing group cylinders.

Abstract: A printing press has at least one ink carrier. A printing substance, such as ink is applied to the ink carrier and at least some of that ink is transferred to a substrate at a separation location. A light-hydraulic effect is used to accomplish this separation. Radiation energy that is transferred to the printing substance stimulates this transfer of the print substance to the substrate to be printed. The transport of the radiation energy takes place by the use of at least two energy beams of different wavelengths.

Abstract: A printing group of an offset rotary printing machine includes at least one forme cylinder, one transfer cylinder and at least one inking system. Two of these printing groups are arranged opposite to each other. The arrangement of the printing group in relation to each other can be arranged in an axial direction which is parallel to the axes of rotation of the cylinders.

Abstract: A printer, that includes multiple printing groups, is mounted in the frame of an offset printing machine. Each printing group includes at least one printing cylinder, at least one transfer cylinder and at least one inking system. Two of these printing groups are arranged opposite to each other. At least one counter-pressure cylinder is arranged between these opposite printing groups. The frame has at least three separable frame modules. At least one printing group is located in a left module. At least one printing group is located in a right module. At least one counter-pressure cylinder is located in a module frame module situated between the left and right frame modules.

Abstract: The invention relates to a printer comprising multiple printing groups (01-04;06-09), which is mounted in the frame of an offset printing machine. The printing groups are each equipped with at least one printing cylinder (11), at least one transfer cylinder (12) and at least one inking system (13), two of these printing groups being arranged opposite each other. At least one counter-pressure cylinder (16-19) is located between said opposite printing groups. This counter-pressure cylinder can interact with at least one transfer cylinder for printing a line of material. The frame has at least three separable frame modules (21-23). The printing cylinder, transfer cylinder and inking system of at least one left printing group (5) are located in a left frame module (21), while the printing cylinder, transfer cylinder and inking system of at least one right printing group are located in a right frame module (23), with at least one counter-pressure cylinder being located in a middle frame module (22).

Abstract: A printing group of an offset rotary printing machine includes at least one forme cylinder, one transfer cylinder and at least one inking system. Two of these printing groups are arranged opposite to each other. The arrangement of the printing group in relation to each other can be arranged in an axial direction which is parallel to the axes of rotation of the cylinders.

Abstract: A roller or a cylinder that is useable in a rotary printing press can accomplish both circumferential as well as axial movement. At least one component of an electric motor can accomplish both the axial and the circumferential movement of the roller. This motor can be integrated into the roller. The surface of the roller can be provided with a suitable covering.

Abstract: The rotation angle position of a moveable component, such as a cylinder, is detected or determined through a method in which the detected rotation angle position is modified using a correction value when the moveable component is in a second position.

Abstract: A device for guiding freshly coated sheets utilizes upper and lower air supply chambers which are both connected to a blower through supply conduits and a return conduit. An arrangement of throttle valves is used to connect one of the air supply conduits to either the discharge or the return side of the blower. This allows the device to operate in two modes, a support mode and a suction mode.

Abstract: A blowing chamber is used for the suspended guidance of sheets or webs. The blowing chamber includes a guidance surface which is provided with a plurality of nozzles. Each of these nozzles has a generally rectangular blower opening which directs air up along an inclined guide surface that terminates at the sheet guidance surface in an arc-shaped transition.

Abstract: Sheets or a web of material are suspended and guided by a plurality of nozzles that direct air out from a closed guidance surface. The nozzles are arranged in a central stabilizing zone and two tightening zones. The air delivered in these zones is directed generally opposite to the conveying direction of the sheets or web and away from a longitudinal axis of symmetry of the closed guidance surface.

Abstract: A cylinder for a rotary printing press is provided with a thin slit into which leading and trailing ends of a plate to be secured to the cylinder are inserted. The slit has two legs that meet at a central apex and define a generally arrow-shaped slit. A plurality of these slits can extend across the cylinder in a zig-zag shape.

Abstract: A plate end of a flexible printing plate is released or ejected from a narrow slit in the surface of a plate cylinder. A rotatable spindle is situated adjacent a radial inner end of the cylinder slit. This spindle carries a group of resilient ejectors having free ends that are engageable with the plate ends during rotation of the spindle and which push the plate ends out of the narrow cylinder slit.
