Abstract

Sprühvorrichtung und Sprühverfahren zum Beschichten von Gegenständen mit Beschichtungsmaterial, insbesondere mit Beschichtungspulver. Es wird nur eine einzige Hochspannungs-Elektrode (26) auf nur einer Seite des Beschichtungsmaterialstromes verwendet, um das Beschichtungsmaterial elektrisch aufzuladen. Dadurch wird ein besserer Wirkungsgrad (weniger Verlust an versprühtem Pulver) erreicht als mit beidseitig des Beschichtungsmaterialstromes angeordneten Elektroden.
