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.

Claims13

Dependent claims

A method, comprising:

ejecting drops of a coating composition onto surfaces of motor vehicle bodies or add-on parts, the coating composition consisting of at least two components which are to be mixed together,
the droplets ejected from a nozzle print head which contains a pair of nozzles arranged side by side which apply the coating composition to the surface to be coated as individual drops, the nozzle print head is arranged on a multi-axis coating robot which moves the nozzle print head over the surface to be coated,
the two components supplied to the pair of nozzles by two supply lines,
the drops of the components of the coating composition ejected from the pair of nozzles at different speeds of travel and at different times so that the drop that is ejected later meets the drop ejected first in mid-air and mixes therewith.
