ABSTRACT:
To permit independent adjustability of the working zones of a doctor blade, without interference of adjustment of one zone (10/1) with respect to adjacent zones (10/2, 10/3), the doctor blade (3) is subdivided by grooves (9) located at the upper surface thereof and positioned in pairs, which extend from the working edge (8) towards the clamping zone (4) of the doctor blade and converging towards each other in V-shaped formation to include an acute angle therebetween and define a transition zone (15) therebetween, the region (14) of the doctor blade beneath the grooves forming fulcrum points permitting hinge-like deflection of adjacent portions or zones of the doctor blade with respect to each other, without mutual interference of adjustment. The deformability of the doctor blade results in exactly defined transfer of ink in each inking zone (11/1, 11/2, 11/3) from the duct roller (2) to the inking transfer rollers of the printing system, without mutual influencing of adjacent inking zones.
