Abstract

The paint applicator uses an electrostatic field to apply a water based paint by means of a high speed rotating disc (5). This has a straight or flanged rim, and a knife edge. Behind the disc is a ring, fitted over the drive spindle casing (4) and provided with an annular row of holes forming jets (3). Its annular chamber (1) is fed with compressed air (2), this passing through the holes as jets. The jets are directed forwards onto the rear of the disc, or at an angle onto the rim. The pressure compensates for the depression generated behind the disc and prevents paint blowback.
