Abstract: The ends of an inking- or dampening-device roller are mounted in respective bearing arrangements displaceable along a control surface co-operating with a guide part. The control surface includes an adjustment zone and a further zone. The adjustment zone runs substantially parallel to an angle bisector of an angle formed by two lines connecting the axis of the inking- or dampening-device roller to the respective axes of the adjacent stationary rollers. Only a single linear drive is necessary for displacing the bearing arrangement.
