Abstract
Adjustment means for engaging, disengaging and adjusting inking and damping rollers are provided in the inking and damping units of offset printing machines. The printing machine includes inking rollers supported on cam rollers which bear on cam discs situated axially parallel to the plate cylinder inside an arcuate housing. The cam discs are interconnected in such manner that they can be adjusted individually and they are also connected to the housing so as to be adjustable jointly. The housing is also pivotally connected to an adjustment drive by means of which it can be moved peripherally relative to the plate cylinder bearing to effectuate the engagement and disengagement position of the inking rollers.
