Abstract

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.
