Abstract: An apparatus and method for utilizing and controlling finer particles in a powder coating system returns the finer particles to the spraying apparatus to be sprayed on parts by the system. Finer particles are continuously removed from the system by application onto parts, and the accumulation of fines is thereby prevented. The finer particles may be sprayed through specially adapted spray guns, which also permits the utilization of the special advantages of spraying fine powder materials. By removing fine powder particles from the system before they build up, the present invention improves the powder coating operation in various respects.

Abstract: An apparatus for cleaning a powder coating booth used to coat elongated articles while oriented vertically includes a pair of opposing vertical walls forming a coating booth, powder spray guns extending through the walls to powder coat articles located therebetween and an overhead conveyor for carrying the elongated articles along a coating line between the walls. A platform mounted to an elevator is vertically movable to any desired elevation in the booth, thereby to enable a cleaning person to clean accumulated powder from the inner surfaces of the walls after a job is finished or when a new color is used. The platform and elevator may be located below the booth, along the coating line. Alternatively, the platform and elevator may be located at a cleaning station away from the coating line and the booth moved to the cleaning station on a wheel-supported rack.
