Abstract
The present disclosure relates to an applicator for applying a coating agent (e.g. sealant) to a component (e.g. motor vehicle body component), having a nozzle for dispensing the coating agent and an elongate nozzle carrier which supports the nozzle. The invention provides that the nozzle carrier has a yield region in which the nozzle carrier is substantially less bend-resistant than in the remainder of the nozzle carrier in order to be able to yield elastically to contact forces in the event of contact between the applicator and the component to be coated.
Claims17
An applicator for applying a coating agent to a component, the applicator comprising:
- a) a nozzle for dispensing the coating agent, and
- b) a nozzle carrier which carries the nozzle,
- c) wherein the nozzle carrier has a yield region in which the nozzle carrier is less bend-resistant than in the rest of the nozzle carrier to yield elastically in relation to contact forces in the event of contact between the applicator and the component to be coated, the yield region includes a hollow supply pipe shaped as a coil spring through which the coating agent to be applied is conducted to the nozzle,
- d) the nozzle carrier has a distal first leg on which the nozzle is arranged,
- e) the nozzle carrier has a second leg which adjoins the distal first leg and is curved at a specific angle of curvature with respect to the distal first leg, the angle of curvature between the distal first leg and the second leg being in the range 60°-120°,
- f) the nozzle carrier has a third leg which adjoins the second leg and is curved with respect to the second leg with a specific angle of curvature, the angle of curvature between the second leg and the third leg being in the range 60°-120°, and
- g) the nozzle carrier has a fourth leg which adjoins the third leg and is curved with respect to the third leg at a specific angle of curvature, the angle of curvature between the third leg and the fourth leg being in the range 60°-120°.
