Patent number: 9505020Abstract: The exemplary illustrations relate to an applicator for applying a coating to a component, for example for applying a sealing compound to an edge-raised seam on a rear side of a motor vehicle body component through a gap between two overlapping motor vehicle body components, with a nozzle for dispensing the coating means onto the rear side of the component and with an elongated curved nozzle carrier in order to position the nozzle on the rear side of the component to be coated, starting from the front side of the component to be coated. It is proposed that the nozzle carrier be curved a plurality of times such that the applicator can be guided through the gap.Type: GrantFiled: June 3, 2009Date of Patent: November 29, 2016Assignee: Duerr Systems GmbHInventor: Lothar Rademacher
