Abstract

The bell plate (1) for the coating of workpieces has an electrode (12) as a channel electrode protruding into the coating medium channel (11). The channel electrode is a needle electrode. Several electrodes may all protrude into the coating medium channel and distributed around the circumference with regard to the rotational axis (5) of the bell plate. The channel electrode is orientated at least partially against the direction of flow in the coating medium channel. An independent claim is included for a rotating atomizer with the aforesaid bell plate.
