ABSTRACT:
Apparatus for finishing the edge of particleboard, plywood and the like by smoothing and sealing the edge with a fast-drying material providing a firm base on which a woodgrain pattern or the like may be printed. The finish developed by extruding and shaping a fast-drying material to a thickness of approximately 5/1000 inch along the edge of the board. Switches are employed to precisely control the application of material when the board is in the vicinity of the applicator. A heating cycle is included in which the edge material is dried and cured after application. The apparatus admits of automatic operation at substantial rates of application with virtually no waste or trimming of the edging material after application.
