ABSTRACT:
In order to coat hollow bodies, which are open at one end, such as a metal can provided with a bottom, with a lacquer or the like, the hollow bodies are passed in a continuous operating cycle through en electrophoretic immersion bath in such a way, that they are rapidly and completely flooded with immersion bath liquid, so that they can be coated electrophoretically with a wet film in the immersion bath. After a sufficiently long coating time, the hollow bodies are lifted out of the immersion bath and the immersion bath liquid, contained in them, is poured out. The hollow bodies, so coated, are carried at a distance from each other to a drying kiln, in which they are dried, whereupon they can be printed or labelled.
