ABSTRACT:
A doctor blade for an inking unit of a rotary printing press utilizes one or more plates or elastic bars to limit whirl flow of the ink in the distribution chamber. The plate and/or elastic bar partially divides the ink chamber. As a result, the creation of whirls is controlled and limited.
