Abstract (en)
[origin: WO9955977A1] An apparatus (10) for forming curved structures having a plurality of pivotally connected sections (12), each section having a track portion (16, 18), and a strap member (24, 26) slidably engaging the track portion of the sections such that the sections are movable to form a radius of curvature. A method of forming a curved structure involves providing runners having a plurality of pivotally connected sections, each section having track portions, and each runner further having two strap members slidably engaging each of the track portions. The method also includes placing runners (42, 44) in an opposed relationship in a curved position such that the runners are substantially aligned, and attaching studs (46) between the runners.
