US Patent 5,771,944 (Lin, granted 30 June 1998) describes a circular weaving loom in which one heddle moves vertically while a second heddle follows an N-shaped path driven by a cam, ratchet, pawl and swing-arm assembly. The movement twists the warps around the wefts to give a thicker, stronger leno-type cloth. The scan holds the USPTO database printout (abstract, claims, description) and the patent drawing sheets, including prior-art figures and an exploded view of the driving assembly.
