Abstract
An electrostatic powder spray coating system for car bodies is disclosed. Above the car bodies (14) are moved through the cabin and from which the spray organs (94) are supplied with powder. The powder container (92) is supplied with fresh powder and recycled powder from a supply container (36). Short paths between the powder container and spray organs allow precise metering and therefore a good coating quality. The spray coating is applied within an arrangement of inner and outer cabins which allows pressurizing of space between the cabins to prevent ingress of atmospheric air into and egress of powder out of the system.
