Abstract
In the context of a printing press inking unit with at least one pitted roll cooperating with two doctor blades offset from each other in the circumferential direction of the pitted roll and preferably carried on a mount so as to define an ink chamber between them into which the pitted roll extends, the wear of the doctor blade removing debris from the pitted roll is reduced if there is a forechamber outside the blade which is upstream in terms of the direction of rotation of the pitted roll, such roll dipping into such forechamber.
