The invention relates to an infinitely adjustable calibrating shell comprising a central piece (1) formed by strips (6, 10) which are hingedly connected to each other and intersect like an extendable lattice that is formed into a shell. Preferably, the ends of the strips (6) are movably connected to annular heads (2, 3). The inner diameter of the central piece (1), which is decisive for the calibrating process, can be modified by axially changing the distance between the annular heads (2, 3), the cross section of the central piece (1) having a circular shape in each axial position.
L'invention concerne un manchon de calibrage réglable en continu composé d'une pièce centrale (1) constituée de bandes (6, 10) articulées les unes avec les autres, se croisant à la manière d'un grillage à ciseaux extensible formé en tant que manchon. Les extrémités des bandes (6) sont de préférence connectées de façon mobile à des têtes annulaires (2, 3). La variation axiale de l'écart entre les têtes annulaires (2, 3) permet de modifier le diamètre intérieur de la pièce centrale (1) présentant une section transversale circulaire dans toutes les positions axiales, caractéristique du calibrage.
