Abstract
La présente concerne une méthode et un appareil de cintrage des tubes, particulièrement adaptés à des tubes à paroi mince ayant un rayon de courbure serré. Un manchon externe est utilisé au cours du processus de cintrage, qui maintient la section transversale du tube et l'épaisseur de la paroi du tube, éliminant ainsi la nécessité d'utiliser un outil de rabattage ou un mandrin interne. Dans un mode de réalisation, le manchon est divisé le long de son axe longitudinal.
