An apparatus (50) for and method of manufacturing helically wound tubular structures (116) includes a rotating faceplate (74) upon which are mounted a plurality of diameter defining rollers (78) which, in operation, cause a strip material (80) to be plastically deformed into a helical winding which may be lain down in abutting or self-overlapping relationship to form said tubular structure (116).

La présente invention concerne un appareil (50) et un procédé de fabrication de structures tubulaires à enroulement hélicoïdal (116). L'appareil comprend un plateau à trous rotatif (74) sur lequel est monté une pluralité de galets définissant un diamètre (78) qui, pendant le fonctionnement, provoquent la déformation plastique d'un matériau en bande (80) pour donner un enroulement hélicoïdal qui peut se déposer à bords francs ou en chevauchement sur lui-même pour former ladite structure tubulaire (116).
