ABSTRACT:
A chambered doctor blade for a short inking unit of a rotary press includes an ink receiving chamber and a profiled body positioned in the chamber. The shapes of the profiled body and the ink receiving chamber are complementary and define an ink flow path. This path is tapered in the direction of ink flow and provides a forced circulation of the ink through the tapered flow path.
