Abstract

L'invention concerne un procédé de fabrication d'éléments d'étanchéité métalliques et de forme annulaire, selon lequel au moins deux bandes de feuille ou de tôle d'épaisseur, de largeur et de longueur définies, sont mises en liaison fonctionnelle sous forme de "tailored blanks" ou de "patchwork", le composite étant ensuite enroulé de manière à former un tuyau. Les zones terminales de ce composite à plusieurs couches et de forme tubulaire qui sont disposées en regard l'une de l'autre sont reliées par liaison de matière, par complémentarité de forme ou à force, voire par combinaison de ces procédés, en particulier par effet thermique, comme par soudure ou brasage, et le tuyau est ensuite séparé en divers éléments de forme annulaire, déformés ensuite par contrainte mécanique pour devenir chacun un élément d'étanchéité ou bien le tuyau est déformé dans sa totalité et le tuyau profilé qui en résulte est séparé en divers éléments annulaires formant des éléments d'étanchéité.
