Abstract

A device for mounting an applicator roller of a dampening unit in a printing machine is disclosed. The device is adapted for rotatably receiving a roller journal of the applicator roller and for fixing that journal relative to the frame part of the printing machine to provide jolt-free operation of the applicator roller. The device is also adapted to provide linear movement of the applicator roller relative to its adjacent plate and dipping cylinders. The device preferably includes adjusting eccentrics mounted one in the other. The adjusting eccentrics are independently adjustable. The eccentricities of the adjusting eccentrics are arranged such that the applicator roller can be thrown-on, thrown-off and set approximately radially both to the plate cylinder and to the dipping roller. As a result of the independent adjustability of the eccentrics, the applicator roller can be optionally thrown-on to the plate cylinder without contacting the dipping roller or vice versa.
