Abstract
A rotary press comprises one or more impression cylinders (1) and a plurality of printing units, each of which comprises an inking unit (I) and an endless block belt (4). The block belt (4) is trained around a plurality of cylinders (5, 6, 7, 8), one of which (7) is movable into engagement with an associated impression cylinder (1). In the rotary press, the block belt of each printing unit is trained around four cylinders, which are disposed at the corners of a square or parallelogram. Two diametrically opposite ones (7, 8) of the cylinders are movable into engagement with the inking unit (I) and a picture-carrying web or an associated impression cylinder, and the two other diametrically opposite cylinders (5, 6) are tensioning cylinders, which are movably mounted in tracks (31) and, by a drive device (39), are movable toward and away from each other.
