Abstract
In a rotary printing machine with directly driven cylinders and at least one directly driven folding unit (12), those drives of the cylinders and their drive controllers which can be assigned to a paper web are combined to form printing-station groups (2). The printing-station groups (2a-d) are connected to one another, to the folding unit (12) and to the operating and data-processing unit (1) via a data bus (3). Within the printing-station group (2), the individual drives of the cylinders and their drive controllers are connected via a high-speed bus system. The printing-station groups (2a-d) acquire their position reference directly from the folding unit (12). The master control system (1) is now responsible only for the presetting of desired values and desired-value deviations and the processing of actual values. The division of the overall control system into a master control system and autonomous printing-station groups (2) achieves that simplicity, flexibility and robustness in respect of faults which is necessary for producing a directly driven rotary printing machine.
