ABSTRACT:
To minimize the number of components of the printing system and require only a single impression cylinder, a sheet transport chain is carried about a second one of three rubber cylinders (3, 5, 7) to receive a sheet from the impression cylinder (2) to which the sheet is first applied for a first prime printing by a first rubber cylinder (3), the sheet being led about the second rubber cylinder and between a third rubber cylinder (7) which applies verso printing thereon, with the second rubber cylinder acting as a counter or impression cylinder for the third rubber cylinder; each one of the rubber cylinders has a plate cylinder (4, 6, 8) associated therewith, the second rubber cylinder applying the second prime print being positioned above the chain drive, the first rubber cylinder and the first plate cylinder being positioned above the impression cylinder (2) and the third blanket cylinder and the third plate cylinder being positioned below the printing cylinder, thus providing for compact construction of the respective cylinders and associated equipment such as damping fountains, ink trains, and the like, without impairment of accessibility to the components of the machine.
