Abstract: The invention relates to a printing unit, comprising at least two pairs of two cylinders each, namely a transfer cylinder and an associated forming cylinder, whereby the transfer and forming cylinders are each embodied with a width sufficient for printing six newspaper pages, arranged axially next to each other and the transfer cylinder co-operates with a printing cylinder embodied as a satellite cylinder to form a printing head in a print-in-place arrangement.

Abstract: The invention relates to a rotary roller printing press with a printing unit for printing a web with six printed pages, arranged axially next to each other, comprising a superstructure in which the web is cut longitudinally into three partial webs, with a folding installation, comprising at least one roller for transporting the partial webs and at least one folding apparatus. The invention is characterised in that the printing unit, the at least one roller for transporting the partial webs of the folding installation and a folding apparatus arranged after the above are separately mechanically driven by drive motors.

Abstract: A printer includes a cylinder pair that consists of a forme cylinder and a transfer cylinder. A satellite or steel cylinder forms a print position as it cooperates with the transfer cylinder of the cylinder pair. The form cylinder and the transfer cylinder are a fixed coupling driver assembly which is driven by a common drive motor. The drive assembly of the cylinder pair and a drive system for the satellite or steel cylinder can be selectively mechanically coupled with each other by use of a coupling.

Abstract: A printing group of a printing press is comprised of at least one pair of cylinders which include a forme cylinder and a transfer cylinder. The transfer cylinder cooperates with an impression cylinder to apply ink to a web of material, with the web being guided vertically. The circumference of at least one of the transfer cylinders and the impression cylinder is an integral multiple, greater than one of the circumference of the forme cylinder. The transfer cylinder and the forme cylinder have respective drive motors that are mechanically independent from the drive of the respective other cylinder.

Abstract: The invention relates to a printing group that comprises at least one form cylinder (03) and an inking system (02) associated with said form cylinder. In the area of its barrel, the form cylinder has an axial length that substantially corresponds to six widths of a printed page. The form cylinder and the inking system are rotationally driven by drive motors (08; 17) that are mechanically independent from each other.

Abstract: A printing unit is comprised of at least one counter-pressure cylinder and a transfer cylinder. A printing point is formed between the two cylinders when they are in contact. The counter-pressure cylinder is actuated by one drive motor independently of the transfer cylinder. In a print-on position, the counter-pressure cylinder is adjusted as a guide variable in relation to the power of the motor which drives the cylinder.

Abstract: In connection with a method for characterization of a layer, a method and a device for determining a characteristic number, as well as a method for selecting a suitable dressing on rollers, or suitable geometries of rollers of a printing press, a characterizing number for characterizing a layer is formed, or employed, which characterizes the roll-off behavior independently of a measuring device or an application in a particular printing group.

Abstract: A drive shaft is provided for a printing group which is comprised of a form cylinder with an inking unit allocated to it, and a second cylinder that cooperates with the form cylinder. The second cylinder forms a printing point with a third cylinder that is not positively connected in a driven manner to the printing group. The form cylinder can be driven by a drive motor. The second cylinder can be driven by a drive connection from the form cylinder. The inking unit allocated to the form cylinder can also be driven by the second cylinder, using the same drive motor.

Abstract: The invention relates to a drive mechanism of a printing unit, having an axially movable form cylinder (01) and a second cylinder (02) cooperating with said form cylinder. The form cylinder can be driven by a drive motor (03) by means of a gear (10; 29) having a spur toothing. The second cylinder can be driven by the form cylinder by means of a drive connection (06; 08; 23; 26).

Abstract: A printing unit is comprised of at least three rotating members, such as an impression cylinder, a forme cylinder that cooperates with the impression cylinder in a printing position, and a roller that cooperates with the forme cylinder. The two, cylinders and the roller may gave a zero rotational speed or a production rotational speed. At least two of the rotating member also have a set-up rotational speed that is different from the zero rotational speed and the production rotational speed of these rotating members.

Abstract: The invention relates to a drive system for a printing group comprising a form cylinder (01), an inking unit allocated to said form cylinder and a second cylinder (02) that co-operates with the form cylinder, said second cylinder forming a printing point with a third cylinder (05) that is not connected by positive-fit in a driven manner to the printing group. The form cylinder can be driven by a drive motor (M). The second cylinder (02) can be driven by a drive connection (06, 08) originating from the form cylinder and the inking unit allocated to the form cylinder is driven by the second cylinder using the same drive motor.

Abstract: A drive mechanism is provided for a printing unit which is comprised of a first cylinder having its own drive motor, and a second cylinder that cooperates with the first cylinder in a printing position and which has its own drive motor. A standard locking gear, which has at least one pair of links which are cooperating with one another and with spur toothing, is arranged between the first cylinder and its assigned drive motor.

Abstract: The invention relates to a method for operating a pressure unit comprising at least one counter-pressure cylinder (03) and a transfer cylinder (04) forming a pressure point therewith. The counter-pressure cylinder is mechanically actuated by means of a first drive motor (06) independently from the transfer cylinder. In a pressure-on-position, the counter-pressure cylinder is adjusted as a guide variable in relation to the power of the motor which drives the cylinder.

The two cylinders and the roller may have a zero rotational speed or a production rotational speed. At least two of the rotating members also have a set-up rotational speed that is different from the zero rotational speed and the production rotational speed of these rotating members.

Abstract: A cylinder drive for a rotary printing press uses bearing rings that are in contact with each other. A friction torque that is produced during the printing process, as a material passes between the cylinder which carry the bearing rings, is approximately compensated by an additional friction torque caused by the cooperating bearing rings.

Abstract: A roller is formed of at least two adjacent roller barrels. Each of the roller barrels has its own shaft that defines an axis of rotation for its associated roller barrel. The axes of rotation of the several roller barrels can be independently positioned. A support is located between the two roller barrels and supports the shafts of the two adjacent barrels. This central support is able to be adjusted.
