Abstract: The disclosure relates to an application device, preferably for alternately applying a 2C material, comprising a first component material and a second component material, on the one hand and the first component material on the other hand, in particular onto a motor vehicle component, comprising preferably an application head and a first line section leading to an application nozzle, wherein the first line section comprises a mixer and a first line for a first component material and a second line for a second component material, wherein the first line and the second line are connected to the mixer and the mixer mixes the first component material and the second component material with each other for forming a 2C material. The application device is characterized in particular in that it comprises a second line section for the first component material to form an application bead of alternately the 2C material from the first line section and the first component material from the second line section.

Abstract: The disclosure concerns an applicator for applying a coating agent (e.g. sealing agent) to a component, in particular for sealing or bonding a flanged seam to the motor vehicle body component. The applicator in accordance with the disclosure first has a nozzle for dispensing the coating agent in a specific jet direction onto a component surface of the component to be coated. In addition, the applicator has a nozzle carrier for positioning the nozzle. The nozzle carrier is hollow on at least part of its length to pass the coating agent. Furthermore, the nozzle carrier comprises a plurality of limbs arranged one behind the other and angled relative to each other. The nozzle is arranged on the nozzle carrier, in particular on the distal limb of the nozzle carrier. The disclosure provides that a spacer, which projects from the distal limb in the jet direction and rests on the component surface of the component to be coated in the coating operation, is mounted externally on the nozzle carrier and thereby sets a predetermined application distance between the nozzle and the component surface.
