摘要:
A printing press has a printing unit with a cylinder and a cleaning device that is mounted for selective displacement into an operating position for cleaning the cylinder and into a maintenance position away from the cylinder. The operating position is located within the printing unit and the maintenance position, although being located outside the printing unit, is located on the press. While the press runs in printing operation, the cleaning device is kept away from the operating position.

A printing press includes a form cylinder, a blanket cylinder, an impression cylinder, an adjusting apparatus having at least one first actuating drive for setting a printing pressure between the blanket cylinder and the impression cylinder, and a tracking system for setting a printing pressure between the form cylinder and the blanket cylinder in dependence on the setting of the printing pressure between the blanket cylinder and the impression cylinder. The tracking system has at least one second actuating drive coupled to the at least one first actuating drive in terms of control technology through an electronic control device, in such a way that the form cylinder is adjusted automatically.
