Abstract
A device for guiding moving articles (,) past at least one ink-jet printing head (,), comprising a conveying belt and a cover belt (,), as well as a guide frame (,) to prevent the depositing of ink drops in the region surrounding the printing heads (,) as a result of air turbulence developing on the edges. The printing heads (,) are located in cutouts in the guide frame (,). In accordance with the invention, flow channels (,) that extend in the article conveying direction are provided at least in the region surrounding the printing heads (,) in the guide frame (,), which flow channels are deep enough so that the flow does not stop. Narrow ridges are positioned between the flow channels (,) and are designed to guide the articles. Narrow guide elements (,) for extending the ridges are located above the ink-jet printing heads (,), in locations where the printing jets (,) are not covered. The ridges and guide elements (,), positioned in article conveying direction after the respective printing head (,), have a lower height (FIG. 1) than those in front to prevent a contact with the printed-on article sections.
