PURPOSE:To enable cleaning and replacement of a plate and a blanket to be easily performed, by removably fitting to a printing unit a water-supplying device for supplying water to an ink-supplying roller. CONSTITUTION:A pair of left and right channel form support frames 17 of a water-feeding part 15 of a water-supplying device W are mounted between inner side surfaces of both machine frames 14, and a water roller 18 and a ductor 19 proximate to each other are fitted to both side support parts 17a of each of the support frames 17. The water roller 18 in the water-supplying device W is rotated by rotating a driving gear G through a turnable gear 18a to transfer water contained in a water trough 16 to the ductor 19. When cleaning a plate cylinder 9, a blanket cylinder 11 and an ink ductor 8 in a printing unit 1 and replacing the plate cylinder 9, a plate 10 and a blanket 12 of the blanket cylinder 11, a handle part 32 of the device W is gripped and lifted upward. Fitting projections 14a on the machine frames 14 are disengaged from fitting recessed parts 2a of a unit frame 2, and the entire body of the machine frames 14 and the water-feeding part 15 is separated from the printing unit 1. |
