ABSTRACT:
The machine substantially comprises two bays (9, 9a) accommodating the rotorgravure cylinders, either one of which is approachable from alongside by a trolley (4, 4a) carrying the print cylinder (6, 6a) and individually accessible regardless of whether the remaining bay is already occupied by a trolley and cylinder or not; each bay is served by its own impression cylinder (10, 10a) and doctor (8, 8a), which operate in conjunction with each replacement print cylinder brought in on the trolley. The speed with which print cylinders can be changed over and recommence operation is considerably enhanced by the design of the improved machine.
