A chamber doctor blade assembly includes axially spaced lateral cheeks that seal the ends of the ink reservoir. Each of these lateral cheeks has a sealing face that conforms to the curvature of the screen roller with which the chamber doctor blade is used. These sealing faces are provided with lubricant reservoirs. The lateral faces also have leading edges bent or flared out to form strippers which remove excess beads of ink from the screen roller.

Chamber doctor blade assembly

Short inking apparatus for a rotary press

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.

Inking unit

In the context of an ink doctor arrangement with at least one doctor blade which is arranged to be carried on a doctor blade mount more reliable operation with less wear and is made possible by arranging the blade loosely in a slot in the said mount.
