ABSTRACT:
The invention relates to an ink ribbon cassette with an impregnation device for printers, in which a container for the ink liquid has in its interior a threshold, across which flows the ink liquid at increased acceleration. One end of an extraction tube opens into the surface of the threshold, the other end of this tube terminating above and adjacent to a roller of sponge or felt. Efficaciously, the threshold forms part of a constriction, through which the ink liquid is urged. The constriction may be formed in that two cavities having narrowing cross-sections face each other or in that a tube is arranged in the container.
