摘要:
A rotary offset printing press has at least one printing unit which is used to print a web with six printed pages arranged in an axial direction next to each other. The printing press also includes a folding apparatus. A transport cylinder of the folding apparatus is arranged with a periphery that can also receive at least six section lengths of the printing product, which six section lengths are arranged in the direction of the periphery of the transport cylinder.

The invention relates to a printing form (19) to be used in a printing unit of a printing press. Said printing form (19) is embodied as a panoramic printing form (19) and supports side by side printed images of a specific number n (n>1) of printed pages having a specific format (F1, F2). The printing form (19) has a width that substantially corresponds to a number of n=3 vertical printed pages in newspaper format (F1, F2) and supports side by side printed images of n=3 pages in newspaper format (F1, F2).
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.

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 geomtries 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.
摘要:
A forme cylinder is supported and adjusted in a printing group of a rotary printing press, which group includes a transfer cylinder and a counter-pressure cylinder, which two cylinders include interacting support elements. The forme cylinder does not include a support element which interacts with the transfer cylinder. The forme cylinder has a shaft distance that can be adjusted during printing to adjust a contact pressure between the forme cylinder and the transfer cylinder. The forme cylinder may be covered with a waterless printing forme. The contact pressure between the forme cylinder and the transfer cylinder can be adjusted to a property, such as the compressibility, of the waterless printing forme.
摘要:
A printing machine has at least one printing unit on which a web of material, which is to be imprinted, is imprinted by offset printing in a variable cut length. A folder is mounted downstream, in the direction of travel of the printed web, of the at least one printing unit. The folder may be located directly or indirectly from the at least one printing unit and has a variable cut length.
摘要:
An offset printing group is part of a printing machine which is used for printing newspapers. The offset printing group includes a printing cylinder and a transfer cylinder. The length of the transfer cylinder corresponds to at least six widths of newspaper pages. Two blankets are arranged adjacent each other on the peripheral surface of the transfer cylinder. A width of each of these blankets in the axial direction of the transfer cylinder corresponds to three widths of newspaper pages.
