US Patent 4,655,863 (granted 7 April 1987 to Miguel V. Franco of Sunol, California) describes a power loom for making pile carpets, tapestry and similar fabrics. Instead of a wide horizontal loom, it uses a stationary cylindrical mandrel surrounded by a rotating annular table carrying identical loom stations, each with a pressure blade assembly, guiding hook and cutter. Yarn strands are adhered to an adhesively coated split-cylinder jute backing and cut at pile height. The patent includes the abstract, claims (including a method claim), background, description of the preferred embodiment, a computer-controlled solenoid system, and ten sheets of drawings (Figs. 1-19). The scan contains both a USPTO web printout and the printed patent.
