Abstract: A scuffing machine is provided for finishing the surfaces of continuously advancing wood products. The machine includes a frame defining a scuffing station, with a conveyor for transporting the wood products through the scuffing station in a generally horizontal feeding direction. A plurality of scuffing brushes are mounted on the frame at the scuffing station for rotation about vertical axes. Each scuffing brush includes a plurality of elongated, vertically extending bristles which terminate in distal ends for engaging the wood products.

Abstract: An apparatus is provided for coating a continuously advancing article. The apparatus includes a housing defining a spray chamber having an inlet end and an outlet end. Walls in the spray chamber form an inlet buffer zone adjacent the inlet end, an outlet buffer zone adjacent the outlet end and a spraying zone between the inlet and outlet buffer zones. A conveyor transports articles to be coated through the spray chamber. A plurality of spray guns are mounted on the housing to substantially surround an article on the conveyor transported through the spraying zone. The spray guns are adapted for spraying an ultraviolet curable coating composition. The spray guns are mounted substantially entirely outside the spraying zone, with only nozzle portions of the spray guns located inside the spraying zone.
