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.

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.

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.

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.

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 dressing is guided onto a cylinder of a printing machine. At least one roller element is used to accomplish this dressing guidance. A support, which includes spaced first and second ends, is provided. The first end of the support is connected to a cross-piece that is running along parallel to an axis of rotation of the cylinder. The at least one roller element is situated on the second end of this support. The support is an elastically flexible body. An actuator is arranged between the cross-piece and the support. The actuator is operable to move the roller toward or away from the cylinder by flexing the elastic support.

A device is provided for the storage of a blanket or a dressing that is to be supplied to a cylinder of a printing machine. A retainer is usable, in a first operating position, to retain the blanket in a first storage position. The blanket can leave the first storage position when it is disengaged from the retainer as the retainer is moved to a second operating position. A second storage position is situated below the first storage position and is vertically spaced from the first storage position along the length of the blanket to be supported. The second storage position stores the blanket that is detached from the retainer before it is supplied to the cylinder. The blankets are stored lengthwise without touching each other. Blankets to be applied to the cylinder are stored in the storage positions one on top of the other.
摘要:
Blankets or packings to be supplied to a cylinder of a printing machine, and having a certain length, are stored in a storage device. A holding element, in a first operating state, holds the blanket in a first storage position. The holding element and the blanket are separated when the holding element moves into a second operating state. When the holding element is detached, the blanket moves into a second storage position that is vertically spaced, along the length of the blanket, from the first storage position. Two holding devices can be used to hold the blanket on two of its opposed sides. When at least one of the holding elements moves into the second operating state, the distance between the two holding elements is at least temporarily enlarged above the dimension of the blanket held by the holding elements.
