ABSTRACT:
This invention refers to a rotary printing machine with at least one counterpressure cylinder and at least two printing belt cylinders around which a continuous printing belt carrying printing forms and printing pictures is led, with one cylinder thereof being provided with a radial ring of pins in the region of each of its ends, wherein the pins thereof mesh with holes of edge-side tracks of holes of the printing belt for a slip-free guiding of the latter. For the solution of the problem to develop a rotary printing machine of that kind which can be easily and rapidly converted for continuous printing belts of different width without exchanging the printing cylinder, the printing belt cylinder is provided with bores at a distance from the end-side pin rings on at least one circumferential line corresponding to the distance of the pin spacing of the pin rings, in which extendable and retractable pins are arranged.
