Abstract (en)
[origin: JPH0342247A] PURPOSE: To prevent a slip between a plate cylinder and an inking cylinder even in the case of a large interval change of shafts by constituting the inking cylinder and the plate cylinder at different diameters to move their surfaces at the same circumferential speed, and connecting a dive gear of a printing machine with a drive gear mounted at the plate cylinder via two intermediate gears. CONSTITUTION: A rubber cylinder 30 and a plate cylinder 31 have different diameters. And, an inking cylinder 32 is wound with a covering material 48 made of a compressible rubber layer. To eliminate a slipping motion at a contact position during operating, the diameter of the cylinder 32 of an operation preparing state is larger than that of the cylinder 31 of the operation preparing state. A shaft 36 of the cylinder 32 is fixedly coupled to a drive motor 45. Since the motor 45 is adjustable, the cylinder 32 can be driven at the same rotational speed as those of the rubber cylinder 30, and the plate cylinder 31. In order to bridge a shaft interval B of the degree for not directly engaging the two intermediate gear having the same partial diameter mounted at shafts 35, 36, a gear 46 has a larger diameter than that of the gear 44.
