Title (EN) TUBE STIFFENING
(FR) RENFORCEMENT DE TUBES
Abstract:
(EN) Devices, systems, and methods are directed to formation of tubular structures, such as spirally formed structures, having spirally extending reinforcing material. In particular, tubular structures can be formed in a continuous process in which a first material is spiral formed along a first spiral and a second material is joined to the first material along a second spiral to reinforce the spirally formed first material. As compared to manual application of reinforcing material, such a continuous process can facilitate producing tubular structures at rates suitable for high- volume, commercial fabrication. Further, or instead, as compared to the use of circumferentially extending reinforcing material to support a spiral formed tube, reinforcing the spirally formed first material with a spiral of the second material may offer certain structural advantages, such as improved resistance to buckling.
(FR) La présente invention concerne des dispositifs, des systèmes et des procédés destinés à la formation de structures tubulaires, telles que des structures formées en spirale, ayant un matériau de renforcement s'étendant en spirale. En particulier, des structures tubulaires peuvent être formées dans un précédé continu dans lequel un premier matériau est formé en spirale le long d'une première spirale et un second matériau est raccordé au premier matériau le long d'une seconde spirale pour renforcer le premier matériau formé en spirale. Par rapport à l'application manuelle de matériau de renforcement, ledit procédé continu peut faciliter la production de structures tubulaires à des vitesses appropriées pour une fabrication commerciale à volume élevé. En outre, ou au contraire, par rapport à l'utilisation d'un matériau de renforcement s'étendant de manière circonférentielle pour supporter un tube formé en spirale, le renforcement du premier matériau formé en spirale avec une spirale du second matériau peut offrir certains avantages structurels tels qu'une résistance améliorée au flambage.
