In a rotary printing machine, there is provided a device for bringing a lacquering/inking cylinder into and out of engagement with at least one of a pair of cylinders including an impression cylinder, the lacquering/inking cylinder being mounted on a shaft, which includes a substantially circular ring turnably disposed on the shaft of the lacquering/inking cylinder, the ring being spring-biased towards two bracing stops and being formed with an indentation at a section of the circumference thereof, the ring being turnable on the shaft so as to move the indented section of the circumference thereof into a position opposite one of the bracing stops for bringing the lacquering/inking cylinder out of engagement with the impression cylinder, the ring being spring-biased in a direction towards the other of the pair of cylinders, the other of the bracing stops being disposed in an open angle formed by an intersection of a line connecting respective axes of the lacquering/inking cylinder and the impression cylinder and a line extending substantially from the axis of the lacquering/inking cylinder to the axes of the other pair of cylinders, and being displaceable by remote control.
