ABSTRACT:
In a flexographic printing press comprising a plurality of plate cylinders and backing cylinders driven by a central gear, the pitch circles of the backing cylinder gears are so covered by the central gear that, if they are projected laterally, they make contact with the pitch circle of the central gear. In the region of contact, the plate cylinder gears engage the central gear as well as the backing cylinder gears. The axes of the backing cylinders are pivotable relative to the axis of the central gear to accommodate plate cylinders of different diameters and maintain the axes of the cooperating plate and backing cylinders on a single diametrial line through the axis of the central gear.
