Abstract
To facilitate expansion of modular printing units (1, 2, 3) and particularly vertical expansion into tower printing stations (1-4; 2-5; 3-6), each printing unit, with its own printing cylinder (20)and drive motor (8-13), has associated therewith a power take-off unit (14-19; 53-56) which, via a right-angle drive, synchronizes a horizontal synchronizing shaft (21) with individual vertical synchronizing shafts (22, 23, 24) of two-tier or two-level or tower printing stations. The power take-off units include continously engaged gears, including bevel gears (79, 80, 81) coupling together the synchronizing shafts and, additionally, coupling a clutch part (76, 78) of the power take-off unit, so that, upon engagement with a second clutch part (77, 75), the synchronizing shaft, individual drive motors (8-13) and the printing cylinder can be coupled together or, upon disengagement of the clutch parts, the motor can drive the individual printing cylinder, independently of synchronized continuous rotation of the horizontal and vertical synchronizing shafts (21, 22-24).
