Abstract

Un dispositif de pliage de matériel (10) comprend un dispositif d’alimentation (300) qui peut aller et venir le long de la direction axiale afin de fournir un matériel cylindrique ; un dispositif de retrait (100) qui coopère avec le mouvement de va-et-vient du dispositif d’alimentation et provoque le retrait du matériel cylindrique dans la direction radiale, en réduisant la pression interne du matériel cylindrique fourni par le dispositif d’alimentation, de façon à plier ledit matériel cylindrique dans le sens axial ; et un dispositif de flambage (200) ménagé autour du dispositif de retrait pour fixer le matériel cylindrique plié. Un procédé de pliage de matériel est utilisé pour réaliser un matériel cylindrique plié axialement. Selon le dispositif et le procédé de pliage de matériel, le matériel plié symétriquement et régulièrement dans la direction axiale peut être obtenu.
