Abstract:
A device for guiding moving articles past at least one ink-jet printing head, preferably in article distribution systems, comprising a conveying belt and a cover belt, as well as a guide frame for guiding the articles disposed between the conveying and cover belts at a defined distance past the ink-jet printing heads, and wherein: the ink-jet printing head or the ink-jet printing heads are respectively located in a cutout in the guide frame; the speed of the articles is high enough, so that air turbulence develops at the edges of the cutout:air flow channels (6) that extend in an article-conveying direction are provided, at least in the region surrounding the ink-jet printing head or heads (3), in the guide frame (1), which flow channels are deep enough so that the air flow does not stop; narrow ridges for guiding the articles are positioned between the flow channels (6); and the ridges, and any narrow guide elements (7), positioned after the printing jets of the respective ink-jet printing head (3) in a transporting direction of the articles (10), and which are designed to prevent contact with the printed-on section of the articles, have a lower height as compared to those located in front of the printing jets.
