ABSTRACT:
To facilitate exchanging the plate cylinders in a flexographic printing press, ink roller blocks and bearings for the plate cylinders are movable by controlled drives on guides substantially tangentially to the impression cylinder to limiting positions suitable for the new plate cylinder sizes and at which the plate cylinder gears are axially displaceable to engage the gears of the inking rollers and the impression cylinder gear. The plate cylinders are displaceable in their bearings between a printing position and an inoperative position at which said gears are still in mesh.
