Abstract: The disclosure relates to an application system for applying an application agent (e.g. sealant) to a component (e.g. motor vehicle body component). The application system according to the disclosure comprises an applicator with at least one nozzle, a supply line for supplying the applicator with the application agent, a sensor which measures a measured variable in the supply line to the applicator or in the applicator and supplies a corresponding sensor signal, and a monitoring unit which is connected to the sensor and evaluates the sensor signal of the sensor. The disclosure provides that the monitoring unit recognizes, by evaluating the sensor signal, whether one of the nozzles of the applicator shows a creeping nozzle clogging.

Abstract: The disclosure relates to a nozzle device for emitting an emission medium onto a component, preferably for emitting the emission medium onto two side faces and preferably an end face of a fold, an edge or a transition joint of the component. The nozzle device comprises an opening configuration for emitting the emission medium and is distinguished particularly in that the opening configuration comprises at least two openings for emitting at least two jets of the emission medium and the at least two openings are oriented inwardly so that the at least two jets approach one another toward the emission side.

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.

Abstract: The disclosure relates to a nozzle device for dispensing a viscous application medium in the form of at least one jet (onto a component, preferably for the encircling application of the application medium onto a rabbet, edge or transition joint of the component (100), wherein the at least one jet defines a jet width. The nozzle device comprises an opening configuration for forming at least one slit opening to dispense the application medium and is in particular distinguished in that the opening configuration is concave to effect a narrowing of the jet width towards the dispensing side. The disclosure also relates to an associated method.
