  • Patent number: 5199989
    Abstract: A pulverulent coating material application and reclaiming system comprises a booth including a floor, a pair of opposed side walls and a pair of opposed ends. Articles to be coated are conveyed through the booth between the walls and above the floor for coating by the pulverulent material. A dispenser dispenses pulverulent material onto the articles as they are conveyed through the booth. A receptacle is provided under the floor for reclaiming pulverulent material which does not adhere to the articles. The floor terminates short of ends of the booth to define adjacent to the ends entries to the receptacle for reclaimed pulverulent material. A floor wiping mechanism includes a wiper, low friction mountings on the wiper to permit low friction movement of the wiper on the floor, scraping blades mounted on the wiper in contact with the floor, and a prime mover for reciprocating the wiper at intervals lengthwise of the floor to return pulverulent material accumulated on the floor therefrom into the entries.
