A method an apparatus (20) for application of sealing or shim material (26) to surfaces (34) is described. The materials are used in particular in the construction of aircraft and other vehicles. The materials are typically interposed in a joint between a vehicle structural element and a vehicle external surface forming component. The scaling materials are adherent. The apparatus of the invention includes a moveable arm carrying an end member (28) having a curved surface. The arm applies the curves surface to a web of the sealing material so that the sealing material becomes wrapped around the curved surface. The arm is then moved to the location of the joint and the web of sealing or shim material is applied to the joint surface by causing or allowing the end member to roll of said surface.

L'invention concerne un procédé et un appareil destinés à appliquer un matériau d'étanchéité ou de compensation sur des surfaces. Les matériaux sont utilisés en particulier dans la construction d'avions et d'autres véhicules. Les matériaux sont interposés en général dans un joint entre un élément structural de véhicule et un composant de formation de surface extérieure de véhicule. Les matériaux d'étanchéité sont adhérents. L'appareil de l'invention inclut un bras mobile qui porte un élément d'extrémité présentant une surface incurvée. Le bras applique la surface incurvée sur une bande du matériau d'étanchéité de telle sorte que le matériau d'étanchéité s'enroule autour de la surface incurvée. Le bras est ensuite déplacé vers l'emplacement du joint et la bande du matériau d'étanchéité ou de compensation est appliquée sur la surface du joint en provoquant ou en permettant l'enroulement de l'élément d'extrémité de ladite surface.
