Abstract
A method for multilayered coating, whereby hurdles for the item that is to be treated are guided for galvanic dip coating (2) through in a separate circuit. Downstream from the tank, the hurdles are changed over (12) and the item that is to be treated is guided in another hurdle for electrophoretic coating through a tank (4) in another separate circuit.
Claims25
An apparatus for coating goods comprising:
- at least one vessel (4) for a treatment bath;
- a driven lifting and displacement frame (15) comprising grippers (25);
- an upper anode (13);
- and
- a lower anode (14),
- wherein said grippers move trays (9) containing said goods to be coated between said upper anode (13) and said lower anode (14).
An apparatus for coating goods comprising:
- at least one vessel (4) for a treatment bath;
- a driven lifting and displacement frame (15) comprising grippers (25);
- a current supply;
- contacting pieces (26);
- and
- fixed contact pieces (32)
- wherein said grippers (25) move trays (9) containing said goods to be coated, wherein said trays (9) are connected to said current supply through said vessel in a gradual manner, wherein said current supply contacts said trays (9) in an alternating way with said contacting pieces (26) positioned at said driven lifting and displacement frame (15), wherein said configuration results in a continuous current supply in said trays (9).
The apparatus as claimed in 8, further comprising an unloading station with linear bearing means which can be moved in between the bearing elements of the trays and rakes which can be displaced over the linear bearing means.
The apparatus as claimed in 8, further comprising a cleaning station with driven cleaning spatulas or displaceable cleaning heads.
