摘要:
A rotary roller printing press has a printing unit for printing a web in six printed pages arranged axially next to each other. A superstructure is used to cut the web longitudinally into three partial webs. A folding installation is used to fold the partial webs and includes at least one roller for transporting the partial webs, and at least one folding apparatus. The printing unit, the at least one roller for transporting the partial webs of the folding installation, and the folding apparatus, which is arranged after in the direction of web travel, the other devices, are each separately mechanically driven by a separate drive motor.

A printing unit is comprised of at least two pairs of two cylinders each. The two cylinders in each pair are a transfer cylinder and a forme cylinder. The transfer cylinder and the forme cylinder are each embodied with a width sufficient for printing six newspaper pages arranged axially next to each other. The transfer cylinder of each pair cooperates with a counter-pressure cylinder, that is embodied as a satellite cylinder to form a printing head in a so-called print-in-place arrangement.

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.
摘要:
A printing unit is comprised of at least two cylinders which cooperate with each other in a printing group. At least one of these at least two cylinders is movably mounted so that it can be positioned against the other of the at least two cylinders by the use of at least one actuator, which is preferably configured as a power-controlled actuator. A control device is provided and in which several different preset values, which represent different levels of contact force between the two cylinders, are stored. Such data storage is in accordance with a criterion which concerns machine data and/or consumed material data and/or operational data. This data is usable to position the cylinder by operation of the actuator.

A dressing is pressed against a surface of a cylinder of a printing machine by the use of pressing elements. Several such dressings may be arranged next to each other in the axial direction of the cylinder. The pressing elements, used in connection with one of the plurality of dressings, are operable independently of other pressing elements that are used in connection with other ones of the dressings. These pressing elements may be provided as roller elements. Additional pressing elements are located, spaced in a circumferential direction of the cylinder, from the other pressing elements. Those additional pressing elements may be positioned before, in a direction of cylinder rotation, the other pressing elements.
摘要:
A cylinder of a printing unit of a rotary offset printing machine has a periphery and an axial length. The peripheral surface of the cylinder is divided, in the axial length, into at least three sections that are positional next to one another. The peripheral surface has, in at least three sections, at least one slot-shaped opening. At least two of the sections each have two openings which are arranged offset with respect to each other about the periphery of the cylinder. The cylinder is intended for use in a cylinder pair including a 6/2 printing cylinder and an associated transfer cylinder.
摘要:
A dressing is pressed onto a surface of a cylinder of a printing machine by the use of at least two pressing elements. These two pressing elements are separated from each other in a circumferential direction of the cylinder. A portion of each of the two pressing elements can be moved toward or away form the surface of the cylinder independently of each other. The pressing elements are preferably arranged on supports that are connected to each other. Each of the pressing elements is provided with its own independent actuator.
