  • Patent number: 5669974
    Abstract: A continuous spray coating apparatus and process generally comprises a housing defining a closed coating chamber, the coating chamber having inlet and outlet openings. Automatic doors are provided to cover the inlet and outlet openings, and the opening and closing of the doors is selectively controlled such that only one of the doors will be open at any one time during the spray coating operation. The introduction of the coating composition into the chamber creates a predetermined atmosphere within the chamber which is substantially saturated with constituents of the coating material, and by means of the automatic doors and control thereof, introduction of air from the outside atmosphere into the chamber is substantially prevented to maintain a predetermined atmosphere within the chamber.
