Abstract

The spray head has an atomiser head (2) on a rotating shaft (4) and a nozzle (8) for the coating material in the interior (9) of the head. Several outlet openings (13) are arranged at an axial distance apart on the periphery of the atomiser head with atomising edges (14) for the coating material. A porous body is used to form the outlet openings and atomising edges.
