Abstract

Zum serienweisen Beschichten von Werkstücken wie beispielsweise Kraftfahrzeug-Karossen mit Effektpartikel enthaltendem Lackmaterial werden elektrostatische Rotationszerstäuber mit Glockentellern (22) verwendet, deren dem Werkstück zugewandte Überströmfläche zumindest im Bereich zwischen der üblichen Verteilerscheibe (40) und der Absprühkante (32) einen konstanten Winkel von beispielsweise ungefähr 60° mit der Rotationsachse bildet.

Figure 00000001
For the serial coating of workpieces such as motor vehicle bodies with paint material containing effect particles, electrostatic rotary atomizers with bell cups (22) are used, the overflow surface of which faces the workpiece, at least in the area between the usual distributor disc (40) and the spraying edge (32), for example, at a constant angle forms approximately 60 ° with the axis of rotation.
