Abstract

In an apparatus for the use of so-called water enamels or some other similarly conductive coating material, the electrical field for charging the sprayed particles is produced between the grounded spraying edge (6) of a bell-shaped atomizer (10) and a large number of external electrodes (10) inserted into an annular element (20) made of an insulating material.
