Abstract

When the type of powder is changed, there is the risk that powder residues of the powder previously used will mix with the new powder and that coating faults will thereby occur. This is avoided in that a plurality of feedlines (13, 17, 14, 18) open into a common delivery line (20) and selectively actuable closing devices (15, 16) are located in the feedlines. Scavenging gas for cleaning the lines is introduced downstream of the closing devices (15, 16). Because the gas is introduced in a turbulent manner, a homogenisation of the coating material is achieved during operation, before it is atomised. The spray method and the apparatus necessary for this are simplified and therefore more economical in operation.
