PROBLEM TO BE SOLVED: To enable a fast and easy control, and obtain a correct and reliable roller assembly at high operation speed by pressing a first roller in the direction of a second roller by spring resilient means, and installing the lock device of the first roller on the frame of a printing machine. SOLUTION: A roller control mechanism 100 is furnished with a flexible roller 102 connected to a roller carrier 104 by means of a shaft 116, and a position securing bolt 108 for fastening the roller carrier 104 to the frame fixing part 114 pierces through a slot 106, and tightens the roller carrier 104 relative to the frame fixing part 114 is position changeable manner. Further, a unit 110 including a spring piston 112 is fixed to the frame fixing part 114, and then by loosening the position securing bolt 108, the roller carrier 104 is moved along a moving axis of the slot 106 of the roller carrier 104 to the position in which a force by the spring piston 112 and a force to the roller 102 by an adjacent roller reach an equilibrium with each other. |
