Abstract

978,763. Spraying apparatus. SOC. ANON. DE MACHINES ELECTROSTATIQUES. Nov. 1, 1961 [Nov. 2, 1960; Dec. 2, 1960], No. 39109/61. Heading B2F. In a method of coating objects by the electrostatic atomization and spraying of a fluid, such as paint, the centrifugal atomization is achieved by a first element 1 of insulating material to which paint is supplied by a pipe 5, the electrostatic atomization is obtained by a second element 3 of high resistivity material to which a high D.C. voltage is applied through a shaft 6 and spring 9 and both elements 1, 3 have sharp edges 1<1>, 3<1> adjacent to one another and facing the object to be coated. In further embodiments the electrostatic element 3 is arranged around the outside of the centrifugal element 1 and the elements 3 and 1 are so disposed that the paint does not contact the element 3. In the arrangement shown both elements are rotated and in other arrangements the element 1 only is rotated. Fins, Figs. 4, 5 and 6 (not shown), may be provided on the outer element 1 to direct a current of air towards the current to be coated.
