The advantages that can be achieved with the invention are in particular that a large one The advantages that can be achieved with the invention are in particular that a large one Diversity of operation and variability of a printing unit or a cylinder assembly is created.

For example, cylinders or cylinder groups can be with different speeds or directions of rotation move what For example, when changing the printing form, when feeding a paper web, when independent Coloring or washing of rollers and cylinders is required. In particular different actions of the setup with from standstill (speed zero) or Production speed different set-up speed or speed for the individual Cylinder types are therefore next to each other, with the paper web running or standing possible.

The simultaneous fulfillment of several different ones is particularly advantageous Requirements for different components of a printing unit or a printing unit. The modes of operation contribute on the one hand to saving time and thus to reducing the Unit product costs and, secondly, enable the implementation of various setup work at in production speed or in Feed speed of running paper web. A flying plate change for the one or Imprint operation on both sides is possible. For example, in advantageous Operating conditions a printing plate changed or pre-inked during the assigned steel cylinder continues to rotate at production speed, or one Washing, pre-coloring or changing the elevator takes place.

In particular for printing units that have a z. B. executed as a steel cylinder Having counter-pressure cylinders opens up various options for setting up the cylinder without interference, while the paper web for example continues to be printed with production speed (flying plate change / imprint operation), is pulled in at a pull-in speed (start of production) or even stops (Preparation work). Together with the printing units according to the invention, these printing units allow Operating modes or states of guiding the paper web with retracting or Production speed while setup work can be carried out on a forme cylinder are. Likewise, the modes of operation allow setup work to be carried out, e.g. B. the Washing and / or changing lifts or printing forms, pre-inking or driving dry, d. H. the decolorization of the cylinders when the paper web is stationary, and without being affected.

Also comes when setting up before starting up or when printing is finished a high level of operating conditions thanks to flexibility and time and waste savings Meaning too. For example, the forme cylinder and the inking roller can be operated simultaneously go through different setup programs.

An independent operation of those assigned to the forme cylinders is also advantageous Rollers for paint application. For example, regardless of the speed and the direction of rotation, washing or pre-inking, while the forme cylinder also undergoes an setup program.
