Abstract

In the electrostatic coating of workpieces with a coating installation in which material sprayed from a grounded rotary sprayer is electrically charged in the corona-discharge area by external electrodes inducing a corona-current to the sprayed material, the danger of the spraying device coating itself is reduced if the corona-current is adjusted to a predetermined value.
