Abstract
To prevent a formation of aerodynamic dead zones in a coating arrangement for powder coating, such as, for example, weld seams, a surface of a supporting member is provided with a constantly increasing radius of curvature between an outlet orifice for a spray jet and an exhaust orifice, starting with the former. A feed conduit is fashioned so that a laminar flow of the coating medium does not experience a change in an arithmetic sign of its path of curvature in the orifice zone and along a subsequent surface. For a constant acceleration of the spray jet, a constant reduction of the flow cross section is provided for the spraying medium between the outlet and the exhaust conduit.
