US Patent 1,418,239, granted 30 May 1922 to Silvio Benigno Crespi of Milan, for a circular loom and weaving process. The shuttle runs continuously in one direction around a circular race, drawn by electromagnets, and the reed beat is replaced by a guide on the shuttle that presses the weft into place. The loom weaves tubular fabric that is cut into several pieces. The document has two sheets of drawings, a description of the construction and operation, and two claims.
