Abstract
A rotatable, electrically chargeable, substantially bell-shaped sprayer for producing a paint mist from an axially fed liquid paint such as 2-component lacquers, for an apparatus for the electrostatic application of sprayed charged particles of the paint mist onto an article, the sprayer having an annular coaxial flowover surface for the liquid paint and an annular lip which projects axially forwardly on a radial and axial outer edge portion of the flowover surface. The lip is provided on its radial inside with grooves for channeling the flow of the liquid paint, the grooves being uniformly distributed on the circumference and extend approximately in the direction of the flow of the liquid paint. The grooves terminate open at a spray position of the lip and intersect in pairs.
