Document Type and Number:
WIPO Patent Application WO2002070147
Kind Code:
A3
Abstract:
A continuous electrocoat apparatus is provided for applying a coating onto a substantially flat substrate, e.g., an electroconductive substrate in coil or blank form. In one embodiment, the apparatus includes a first electrocoat tank having a coating region and a non-conductive conveyor extending at least partially into the first electrocoat tank and defining a conveyor path. A plurality of electrically conductive supports are carried on the conveyor. A connecting system is configured to selectively place at least a portion of the supports in electrical contact with an electrical power source when the selected supports are in the coating region of the first electrocoat tank.
