Apparatus for spray coating a continuously advancing article

摘要

An apparatus is provided for coating a continuously advancing article (12). The apparatus includes a housing (14) defining a spray chamber having an inlet end (16) and an outlet end (18). Walls in the spray chamber (64) form an inlet buffer zone (64a) adjacent the inlet end (16), an outlet buffer zone (64b) adjacent the outlet end (18) and a spraying zone (64c) between the inlet and outlet buffer zones. A conveyor (54) transports articles (12) to be coated through the spray chamber (64). A plurality of spray guns (48) are mounted on the housing to substantially surround an article on the conveyor (54) transported through the spraying zone (64c). The spray guns (48) are adapted for spraying an ultraviolet curable coating composition. The spray guns (48) are mounted substantially entirely outside the spraying zone (64c), with only nozzle portions of the spray guns (48) located inside the spraying zone (64c). <IMAGE>An apparatus is provided for coating a continuously advancing article (12).
