Abstract
Abstract A powder spray booth for use with an electrostatic powder spray gun for coating objects in an electrostatic field as said objects are passed through the booth. The booth includes a bottom panel on which is fixedly mounted a front panel, a rear panel and a pair of side panels. A top panel is operatively mounted on top of the last-named panels. All of the aforementioned panels are made from molded fireproof fiber glass material. Each of the side panels is integrally connected to the adjacent front and rear panels by rounded corner portions. The top and bottom panels are each provided with rounded corners. Each of the side walls is provided with an opening for the passage therethrough of a workpiece to be sprayed with powder. The front panel has an opening for admitting a powder spray gun for spraying the workpiece. At least one powder outlet opening is provided in one of the panels. The top panel has a longitudinal opening for the passage therethrough of a supporting means for the workpiece, and a metallic powder collecting means, at ground electrical potential, is disposed around each side of said longitudinal opening in the top panel.
