Abstract (en)
[origin: EP0596817A1] Method, device and apparatus for surface treatment, such as a coating and/or a cleaning of bodies of metal cans, preferably made of Al and its alloys, more particularly of bodies of cans obtained by deep drawing, drawing-deep drawing or impact extrusion. The device according to the invention comprises at least the following components: a) a nozzle (23) of electrically conductive material such as graphite or stainless steel, pierced with an axial channel, substantially vertical in direction, on which a can body to be treated can be arranged upside down, b) guiding means (6) permitting an easy displacement of the can body in a substantially vertical direction, c) an electrode (11) forming an electrical contact and situated above the bottom of the can body. The method consists in conveying a basket containing the cans from an (electrolytic) cleaning station to a rinsing station and then to an (electrophoretic) coating station and finally to a rinsing station. The invention finds its application in the packaging industry. <IMAGE>
