ABSTRACT:
To permit selective operation of a rubber blanket--plate cylinder couple located, respectively, above and below an impression cylinder for double prime printing, prime-and-verso printing, or printing plate change while printing is carried out with a remaining couple and during operation of the machine, two clutches (21 or 25) selectively feed a main rotary drive from a main gear (18, 19) to the drive gears (22, 23) of the upper blanket cylinder--plate cylinder couple (2, 4) or, upon operation of a clutch (25) via drive gears (26, 27) to the lower blanket cylinder--plate cylinder couple (3, 5). For prime-and-verso printing, only one of the clutches (e.g. 21) is operated. A further clutch (29) located on the shaft (13) of the upper blanket cylinder (2) can be coupled to the blanket cylinder shaft by a third clutch (29) which, for plate exchange during machine operation, is disengaged and, upon engagement, permits operation of the second blanket cylinder--plate cylinder couple in reverse direction--with respect to double-prime printing--while the second impression cylinder (25) then will spin freely on its shaft.
