L'invention porte sur un appareil d'enroulement et sur un procédé de fabrication de structures tubulaires à enroulement hélicoïdal (116) qui comprenant une plaque de contact intérieure rotative (74) sur laquelle sont montés une station de formation destinée à constituer une alimentation de matériau en bande avant que celui-ci ne soit enroulé sous la forme d'une structure désirée et une pluralité de supports intérieurs sous la forme de rouleaux (110) montés pour la rotation autour d'un axe, ladite plaque de contact intérieure et une pluralité de rouleaux d'entraînement extérieurs (92) étant disposés sur une plaque de contact extérieure (118). Les rouleaux intérieurs (110) sont montés pour un déplacement radial par rapport à la plaque de contact intérieure (74). En fonctionnement, les rouleaux intérieurs (110) agissent de façon à porter une partie intérieure S1 de matériau en bande enroulée sur ceux-ci tout en permettant à celui-ci d'être alimenté à partir d'un diamètre intérieur de celui-ci vers ladite station de formation et les rouleaux extérieurs (92) agissent pour porter une partie extérieure S2 de ladite bande. Lesdits rouleaux extérieurs sont entraînés si nécessaire afin de transporter le matériau vers la partie intérieure S1 et la position radiale des rouleaux intérieurs augmente lorsqu'on consomme le matériau en bande à partir d'un diamètre intérieur, afin de maintenir ainsi le support de l'alimentation de bande indépendant de la quantité consommée.
