Abstract
Known processes for coating hollow bodies such as cans are problematical in terms of productivity and contamination caused by high rotational speeds of the application rolls due to lacquer splashes and lacquer mist. These problems are solved by means of a process and a device for the application of several coatings to cylindrical hollow bodies by rolling the hollow bodies on an application device having a lacquer film wherein several hollow bodies roll on the lacquer film one after the other and wherein, for the application of at least the first coat of lacquer such hollow body rolls in the lacquer film which is progressively reduced by separation of lacquer on the application of lacquer to the preceding hollow body or bodies.
