ABSTRACT:
The apparatus and system utilize sprays of steam to clean the exterior or laminated objects, preliminary to electrostatic powder coating, as well as to effect volatilization of liquid contaminates trapped between lamina thereof. Off-gassing that would otherwise occur when the objects are heated to effect fusion of the powder deposit is thereby avoided. The apparatus includes a conveyor for transporting a workpiece along a horizontal travel path through a chamber, above and below which path a spray compartment and collecting compartment are defined, respectively.
