Abstract: An improved transfer device comprised of powered endless surface elements for supporting and moving coated articles in an upright position, such as coated can bodies, from one treatment station, e.g. a coating station to a further treatment station, such as a coating/curing oven. Various parts of the endless surface elements are arranged at selected levels in a trough through which a suitable aqueous medium, e.g. deionized water, is substantially continuously circulated. The height within the trough of this aqueous medium is advantageously controlled relative to the top surface portions of the endless surface elements so that there will be a substantially continuous cleaning of the endless surface elements as excess coating material moves towards and drains from the lower portions of the article being transported while the article is moved through the trough by way of the endless surface elements.

Abstract: An improved system for washing and coating metal can bodies, such as seamless aluminum and tin plate can bodies, in a can processing line wherein various can washing, coating and curing stations are arranged in a unique fashion along the line so as to utilize generally fully compatible washing and coating materials, the residues of which are adapted to be either recycled or discharged into a common waste disposal system, as well as an improved coated can body.
