US Patent 4,143,685, granted 13 March 1979 to Cambridge Consultants Limited, describes a loom in which warp yarns pass through a retraction region and a shedding region. Gaseous fluid flow along grooved channels forms loops in the warp yarns to open the shed, and mechanical detent devices (rotors, belts or reciprocating elements) draw the yarns into tension to close the shed and to beat up the weft against a fixed reed. The scan includes a USPTO database printout with abstract, claims and description, the patent's printed first page, and eight sheets of patent drawings (Figs. 1-9) showing the loom mechanism, yarn feeding and weft carrier elements.
