ABSTRACT:
A chambered doctor blade utilizes parallel, axially extending spaced working and sealing doctor blades, together with spaced end plates to define an ink chamber. Free axial ends of the working doctor blade extend beyond the ends of the end plates and remove built-up ink beads. This removed ink flows down the surface of the inwardly inclined end plates.
