ABSTRACT:
A pneumatic powder flow diverting device for use in conjunction with an apparatus for the electrostatic coating of can bodies which are sequentially positioned for receiving the powder coating. A pneumatic switching device is provided so that powder is directed to the position of a can body to be coated only when a can body is located in that position. A return line returns the powder flow to a powder source during the time between can bodies. The pneumatic switching device utilizes small air jets for diverting the powder flow between the coating apparatus and the return line with a minimal amount of air being required to effect the switching operation.
