A method of assembling a brush seal between two components (15, 16) having confronting adjacent surfaces (18, 24), such as the stator and rotor of a gas turbine, comprises providing a slot (19) in one of the components (16) which slot opens through the confronting surface of that component to face the other component (15). A flexible brush seal element (23) having a plurality of metallic bristles (25) is pushed into the slot (19) so that the free ends (29) of the bristles project from said surface of the one component. The element (23) is then held in position in the slot (19) by means of an anchoring strip (28) pushed into the slot so as to bear on a wall (20) thereof and also on the brush seal element (23), the anchoring strip tipycally being of a malleable metal.
L'invention concerne un procédé d'assemblage d'un joint à brosse entre deux éléments (15, 16) ayant des surfaces opposées adjacentes (18, 24), telles que le stator et le rotor d'une turbine à gaz, lequel procédé consiste à pratiquer une fente (19) dans un des éléments (16), s'ouvrant sur la surface opposée de cet élément afin de faire face à l'autre élément (15). On enfonce alors dans la fente (19) un élément de joint à brosse souple (23) pourvu de plusieurs soies métalliques (25), de manière que les extrémités libres (29) des soies dépassent de ladite surface de l'élément. On maintient ensuite l'élément (23) en position dans la fente (19) au moyen d'une bande d'ancrage (28) enfoncée dans la fente de manière à soutenir une paroi (20) de ladite fente ainsi que l'élément joint à brosse (23), cette bande d'ancrage étant généralement constituée d'un métal malléable.
