ABSTRACT:
An electrostatic powder coating system usable for coating articles transported along a substantially non-conductive article transport conveyor belt supported by a substantially non-conductive slide member. The system includes a substantially non-conductive coating booth with an open side portion supported by an upright support member disposed on a movable base member. The coating booth is laterally movable toward and away from the conveyor, and the coating booth is movable along the upright support member so as to position the coating booth downwardly toward and upwardly away from the conveyor. An electrostatic coating applicator is directed into the coating booth for applying powder coating to articles transported along the conveyor. A coating collector includes a coating booth exhaust duct coupled to the coating booth, and a conveyor exhaust duct laterally movable toward and away from the conveyor. An air knife directed toward the movable article transport conveyor belt separates powder coating from the belt and directs powder coating toward the conveyor exhaust duct where it is collected for reuse.
