Abstract
In a mechanism for selectively obtaining two extreme positions of printing cylinders, i.e. a contact of four cylinders except an impression cylinder and a contact of five cylinders including the impression cylinder, through effecting angular displacements of eccentric sleeves attached to respective printing cylinders simultaneously by a common link mechanism, an angle increase shifting mechanism is interposed between the starting end of the link mechanism and the end of an actuator. Whereby, the pair of printing cylinders can be directly shifted from one to the other extreme positions by a single stroke of the actuator. A member attached to a main shaft of the angle increase shifting mechanism is divided into three pieces of a front piece, center piece and a rear piece, and the center piece is adapted to be selected engaged by and disengaged from the front and rear pieces by means of a pin clutch mechanism. Whereby, the shifting to the intermediate mode is possible independently and branchingly from either of the two extreme positions after completion of the switching to either positions.
