摘要:
A web-fed rotary printing press includes a printing unit which has a specific width for printing a web with six adjacent vertical printed pages in a first newspaper format. A longitudinal cutting device is used to divide the web into three partial webs, each of which having a width corresponding to two of the newspaper pages. A folding assembly includes a group of three fold formers which are located next to each other on a machine plane. The three formers are disposed in the web-fed rotary press in such a that the two distances between the folding planes of two of the formers, which are placed next to each other in pairs, can be modified.

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).

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.

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.

摘要:
A printing press is comprised of at least one dry offset printing unit. At least two different webs can be fed through the dry offset printing unit. In a first production mode “C” of the printing press, a first web is fed through the dry offset printing unit without a subsequent drying process. In a second production mode “H” of the printing press, a second web is fed through the dry offset printing unit and through an active dryer. In both the first and second production modes “C”, “H”, an inking unit of the printing unit is filled with the same ink.
摘要:
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.
摘要:
A printing group of a printing press is comprised of at least one pair of cylinders which include a form 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 form cylinder. The transfer cylinder and the form cylinder have respective drive motors that are mechanically independent from the drive of the respective other cylinder.
摘要:
A characterizing number for a cylinder dressing having an elastic layer is determined. The characterizing number is then usable to select suitable geometries of rollers in a printing press. If the roller geometry is already known, the characterizing number facilitates the selection of a suitable dressing. The characterizing number characterizes the roll-off behavior of a dressing independently of a measuring device used to determine the number or an application in a particular printing group.
