Abstract
A mechanical 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 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 the powder source during the time between can bodies. The switching device utilizes a readily bendable deflectable tube for diverting the powder flow between the coating apparatus and the return line and in order to prevent a backflow of powder during the switching, each of the lines receiving powder from the tube includes a vacuum flow transducer whereby the customary dead air resistance to flow of the powder-gas admixture is eliminated and, therefore, there is no blow back of powder during the switching operation.
