Abstract: A method and a cylinder arrangement for a printing apparatus is provided in which printing plates (16,17) or punching plates (16,17) of different lengths may selectively be mounted on the same plate cylinder (12,13), and wherein a web (10) to be printed or punched may be moved past the cylinder (12,13) at a substantially constant speed. Two or more formats (18,19) may be interlaced on the web (10). The formats (18, 19) may be of different lenghts in the longitudinal direction of the web (10). Adjustment means for adjusting web length between printing units or between contact points between the web (10) and plates (16,17) within the same printing unit are not needed.

Abstract: A highly flexible printing apparatus is provided comprising printing modules (A-F) and cassettes (8) containing different web processing means. Each of the cassettes (8) is adapted to be mounted on a selected printing module (A-F) to cooperate with the module (A-F) during production of printed matters and contains means for a specific web processing technology that will be provided by the selected printing module (A-F) when the cassette (8) has been mounted to it. The different cassettes (8) may contain web processing means of a great variety, such as offset printing means, dry offset printing means, letterpress printing means, serigraphy means, hot foil application means, flexographic means, raised printing means, punching means, means for printing electronically generated images, etc.
