Abstract

The disclosure concerns an applicator for applying a coating agent (e.g. thick matter) to a component (e.g. motor vehicle body part) with a nozzle with a nozzle opening with a certain nozzle geometry, in particular for applying a thick matter bead to a component surface. The disclosure provides that the nozzle geometry of the nozzle opening can be adjusted without replacing the nozzle, in particular by a relative movement of two nozzle parts. Furthermore, the disclosure comprises an exchange part for such an applicator and an operating method therefor.
