Abstract

An application device for the application in series of a paint or other coating compositions to motor vehicle bodies or add-on parts thereof has a nozzle print head which contains a plurality of nozzles arranged, for example, in one or more rows, which apply the coating composition to the surface to be coated as continuous jets or individual drops. The nozzle print head is arranged on a multi-axis coating robot. In contrast to application devices of this type known hitherto, the coating composition consists of at least two components which are to be mixed together, such as, for example, 2K paint, which are fed to the nozzle print head via separate supply lines for jointly supplying the nozzles.
