Abstract

Electrostatic powder-spraying device with a charging electrode (20) for the electrostatic charging of powder for the spray-coating of articles and with at least one counterelectrode (52) for the electrostatic extraction of free ions from the stream of sprayed powder. An electrical conduction path (60) for connecting the counterelectrode (52) to a different electrical potential from the charging electrode (20) contains a ring-contact connection (68). The powder-spraying device can be demounted in a simple way for cleaning and can also optionally be used without a counterelectrode (52). <IMAGE>
