US Patent 4,074,543 (Frederick O. G. Schmidt, Allura Corporation, granted 21 February 1978) describes a lace or net fabric and its manufacture on a raschel warp-knitting machine. The net has a repeating pattern of squares enclosing small six-sided figures, imitating bobbin-net (Leevers) lace while staying dimensionally stable in both warp and weft directions. The patent explains the chain-stitched wales and laid-in unlooped threads, gives guide-bar chain notation for two variants, and notes the preferred 36-gauge machine with a 12-course repeat. Patent drawings show the thread arrangement, pattern chain, guide-bar threading and fabric repeats.
