Abstract

1349375 Electrostatic coating gun GRACO Inc 4 May 1971 [6 May 1970] 12967/71 Heading B2F An eleectrostatic coating gun has an electrode 3 extending within a pipe 2 supplying the coating material and a second electrode outside the pipe 2. The pipe 2 may be made of an insulating material, the electrode 3 may consist of a bare wire running inside the pipe and the second electrode 4 may be in the form of a coil wound externally round the pipe. Powder entrained in air by means of venturis becomes ionised by means of the difference in potential between electrodes 3 and 4 and polarised by friction between the particles themselves and the walls of the pipe. Pipe 9 is adjustable to enable a narrow or diffuse spray of powder to be sprayed.
