  • Patent number: 7781012
    Abstract: A method and an installation for coating, especially painting, articles. The method is characterized by filling nonabrasive powder containers with the powdery coating material and transporting the containers to the vicinity of an application device. The powder containers are opened only in the vicinity of the application device and the powder is removed and then released by the application device onto the article to be coated. The avoids substantial dirtying of the transport paths that the powder containers are transported on, thereby eliminating the need for cleaning when the coating material is changed, especially when the coating powder is changed.
