ABSTRACT:
A machine for the coating of a strip material substrate, flat stock or the like has a plurality of spray coating guns applying coating material to the substrate. A sloping ceiling and nozzle support assembly causes any coating material deposited thereon to flow along these surfaces to the side of the substrate rather than collecting above the substrate and dripping on the substrate and degrading the desired finish. In a rotary coater, the sloping ceiling and nozzle support assembly can be combined into one rotating structure wherein centrifugal force arising from the rotation of the structure causes any coating material deposited on it to travel to its outer rotating edge where it is thrown clear of the substrate. Troughs over the entrance and exit openings of the coater collect coating material which would otherwise drip onto the substrate from above the openings and carry such coating material clear of the substrate.
