を特徴とする平版印刷機の給水装置。 In a lithographic printing press equipped with a plate cylinder that can be attached to and detached from a mating cylinder, the nip pressure between the plate cylinder and the plate cylinder is maintained at a constant level by the swinging of the arm that is supported by a swingable arm and linked to the movement of attaching and detaching the plate cylinder. a mounting roller that moves while moving and is attached to and removed from the plate cylinder by the swing of an arm, and a water roller that is close to the mounting roller and whose circumferential surface is immersed in dampening water in a water tank and is rotatably supported. and a swinging lever that is swingably supported on the bearing side of the water head roller, and a swinging lever that is pivotally supported by the free end of the swinging lever and is attached to and detached from the application roller by swinging the swinging lever by a driving means. a metering roller pivotally attached to the free end of the swing lever, and a roller having a rotation axis coaxial with the formation roller and rotatably supported on the arm side and rotatably supported on the arm side. 1. A water supply device for a lithographic printing press, characterized in that an eccentric cam for regulating inter-roller nip pressure is provided to bring the roller into contact with an outer peripheral cam surface when the metering roller and the forming roller are brought into contact.
