US Patent 4,046,173 (6 September 1977), granted to Karol Kulczycki and assigned to Barber-Colman Company, describes a triaxial weaving machine in which elongate strip heddles are arranged in weftwise rows and shifted weftwise to move warp strands from one weftwise location to another. Stationary guide plates support the heddles while shedding bars engage cutouts in them and move them longitudinally to form warp sheds for weft insertion. The document includes the abstract, 12 claims, a description of the drawings and mechanisms (cams, cranks, drive links, heddle shifting bars), and three sheets of patent drawings. It appears twice: as a USPTO web printout and as the original patent layout.
