US Patent 5,242,745 (granted 7 September 1993) to Jean Aucagne and Laurent Martinet, assigned to Brochier S.A. of France, describes a spiral-shaped woven textile structure. Warp yarns are arranged in spirals around a common axis, and each weft yarn runs along a radius between a starting yarn and a reference yarn, so the fabric stays uniform in each annular region. The text covers the claims, the background on conventional tapered-roller spiral weaving, and the weaving process and loom. It also gives comparisons of the thickness and surface mass of spiral fabrics made by different methods. The scan is a printout from the USPTO database, with the patent's front page and a figure of warp yarns 1-17 and weft yarns A-S.
