PROBLEM TO BE SOLVED: To replace a plate cylinder without removing a furnisher roll. SOLUTION: A furnisher roll 10 is supported at the lower end of a roll supporting arm 11A which can revolve around an axis O positioned above a plate cylinder 3, the rotation of a rotary actuator 32A is transmitted to the arm 11A through an intermediate gear 23A and an arm gear 24A to push the roll 10 to the plate cylinder. In the replacement of the plate cylinder 3, the intermediate gear 23A is rotated with the actuator 32A in the arrow E direction to revolve the arm 11A to an almost horizontal state so that the furnisher roll 10 is moved to a refuge position P2 located above the plate cylinder. |
