Abstract
Device for the electrophoretic coating of the internal surface of electrically conductive hollow bodies, in particular of packaging cans, having at least one mount, forming the anode or cathode, for at least one hollow body with the opening pointing downward, at least one nozzle, which can move axially in relation to the hollow body as far as the opening, for a water-soluble surface coating agent, which produces the connection to a cathode or anode, as liquid electrolyte of an electrically insulating seal, for the nozzle in the opening in the hollow body, and at least one return flow passage in the region between the nozzle and the internal edge of the opening in the hollow body.
