US Patent 4,977,933 (Joseph E. Brais, assigned to Joss Company, granted 18 Dec 1990) for a circular loom that weaves tubular fabric from flat ribbon-shaped weft. The shuttle assembly travels a circular path carrying its own weft supply, motor and shed-forming means. A cam-driven disk and ratchet mechanism pre-orients the warp ends for the pattern. The scan includes a USPTO database printout with abstract, citations and claims, the patent as printed with 7 sheets of drawings, and the full specification. The specification describes the shuttle, fabric take-up and warp orienting mechanisms, with plain weave and herringbone pattern examples.
