Slotted doctor blade or applicator device, which in the interior of a screen cylinder or a rotating stencil is arranged

摘要

The slotted hole squeegee or inking device (2) has a long narrow slot (3) extending in the direction of the medium application area (10), which slot widens upwards in diverging surfaces or wall parts (30') or in upwardly curved rounded areas (30), feed guides (4,40) for the medium being assigned to the upper widened area, which feed guides extend over the length of the slot (3). The diverging surfaces or wall parts (30') or the rounded areas (30) are to be built up on the walls (31, 32) forming the slot (3) and to be guided upwards and outwards approximately over a range of 90 DEG . By this means, when a foamed medium is fed in, the foam is guided in such a way that none of the foam bubbles can burst, with the result that no foam residue can arise which could cause application errors.
