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.

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 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 a pair of cylinders, such as a forme cylinder and a transfer cylinder. These two cylinders, together with a third cylinder, form a printing site. The third cylinder is in contact with the transfer cylinder. The forme cylinder and the transfer cylinder are coupled together and form a drive system which is driven by a common drive motor during the printing process. Power is transmitted from the transfer cylinder to the forme cylinder. The drive system for the cylinder pair and a drive for the third cylinder are coupled to each other by a mechanical coupling for selective coupling and decoupling.

A rotary offset printing machine uses a plurality of printing units placed inversely by 180° with respect to a vertical line with respect to each other. The drive assemblies for the cylinders of the inversely placed two printing units are also inversely disposed.

A cylinder of a rotary printing press is driven by a hollow shaft electric motor. The cylinder is supported in eccentric bushings and can be re-positioned. A coupling assembly, that includes two couplers and a connector shaft, is used to connect the shiftable cylinder to the fixed motor.

A printing tower of a press can be divided into two side frames. A platform can be moved in a vertical direction between the two side frames. A securing device is provided and is constructed as a crash safeguard and is configured such that the securing device can be moved, together with the platform, in the vertical direction. The securing device can also be moved relative to the platform. A method for providing a platform of a printing tower of a press is also disclosed, which press is divided by one movable side frame being moved relative to another side frame. As a result, an intermediate space is provided. A lifting device is arranged in the intermediate space and may be released by the displacement conveying the platform into the intermediate space in the vertical direction into a desired position. Following the displacement of the mobile side frame, the securing device is moved relative to the platform and the securing device, together with the platform, can be moved in the vertical direction.
