Dabei werden die der betreffenden Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 nacheinander zuzuführenden Bogen zum Erreichen und/oder zum Beibehalten einer von der Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 zu erbringenden hohen Produktivität von der Transportvorrichtung jeweils vorzugsweise in einem minimalen, aber i. d.

Wenn ein Bogen kürzerer Länge in der betreffenden Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 nach einem Bogen größerer Länge zu bearbeiten ist, wird der Bogen kürzerer Länge von der Transportvorrichtung durch eine Erhöhung seiner Transportgeschwindigkeit beschleunigt. Umgekehrt wird ein Bogen größerer Länge von der Transportvorrichtung durch eine Verringerung seiner Transportgeschwindigkeit verlangsamt, wenn der Bogen größerer Länge in der betreffenden Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 nach einem Bogen kürzerer Länge zu bearbeiten ist. Als Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 wird vorzugsweise eine Non-Impact-Druckeinrichtung 06 verwendet, deren Produktivität i. d.

Therefore, the generally rectangular arc differs z. B. in their respective length, with this length each extending in the transport direction T of this arc. To when using a trained in particular as a non-impact printing device 06 Processing station 02; 03; 04; 06; 07; 08; 09; 11; 12, the sheets are fed sequentially to reduce the productivity of the respective machine assembly at relatively shorter sheets, ie in sheets of smaller format compared to otherwise larger-sized processed in this machine arrangement sheets, a method is proposed with the following method steps:

If a sheet of shorter length in the respective processing station 02; 03; 04; 06; 07; 08; 09; 11; 12 is to be processed after a larger arc length, the sheet shorter length is accelerated by the transport device by increasing its transport speed.

If these sheets are still to be supplied in each case at a constant distance from each other of the non-impact printing device 06 regardless of their respective format, sheets of greater length are slowed down less than shorter sheets, but in any case, a reduction in their respective transport speed may be required because the processing speed of the non-impact printing device 06 is generally lower than the production speed of the offset printing device 04.
