Beschreibung
Zusammenfassung:	The invention relates to a flexible metal pipe spirally wound from profiled metal strips, wherein the width of the strip profiles is greater than the axial pitch measured at the direction of the principal axis of the flexible metal pipe, and the profiles may slide over one another as the flexible metal pipe is bent the essential feature of the invention being that the strip profile is made from at least two substantially or partially overlapping strips (1, 2, 3...i). The invention also relates to manufacturing the above product, to apparatus for manufacturing the product, as well as to the application of the flexible metal pipe according to the invention. L'invention porte sur un tube métallique flexible enroulé en spirale à partir de bandes métalliques profilées, dans lequel la largeur des profils de bande est plus grande que le pas axial mesuré dans la direction de l'axe principal du tube métallique flexible, et les profils peuvent glisser l'un sur l'autre lorsque le tube métallique flexible est courbé, la caractéristique essentielle de l'invention étant que le profil de bande est fait d'au moins deux bandes sensiblement ou partiellement chevauchantes (1, 2, 3, i). L'invention porte aussi sur la fabrication du produit précité, sur un appareil pour fabriquer le produit ainsi que sur l'application du tube métallique flexible selon l'invention.
