Patent number: 10507483Abstract: A coating method for coating components, e.g. motor vehicle bodywork components in a painting installation, is provided. The coating method includes moving an application device over a component surface to be coated along a pre-determined coating path, and applying a coating medium stream onto the component surface by means of an application device. The coating medium stream is not rotationally symmetrical relative to its stream axis and therefore generates on the component surface an elongate spray pattern with a particular longitudinal direction. The method further includes rotation of the application device about the stream axis relative to the coating path during the movement of the application device so that the angular position of the longitudinal direction of the spray pattern relative to the path transverse direction changes along the coating path.Type: GrantFiled: November 4, 2015Date of Patent: December 17, 2019Assignee: DÜRR SYSTEMS AGInventors: Hans-Georg Fritz, Benjamin Wöhr, Marcus Kleiner, Timo Beyl, Moritz Bubek
