Abstract

A seal for a chamber doctor blade (12) of a printing machine, with a sealing block (30) of a pliable material, which is inserted at one end of the chamber doctor blade between two doctor blades (16, 18) and closes off an inking chamber (20), bounded by the periphery of an applicator roller (10) of the printing machine, the doctor blades and a housing (14) of the chamber doctor blade, in which the surface of the sealing block (30), facing the applicator roller (10), is covered with a strip (34) of elastic material, which is harder than the material of the sealing block.
