US Patent 4,307,496 (29 Dec 1981) by Noboru Nakagaki and Yoyu Fujikawa, assigned to Takeda Lace Co., Ltd. of Fukui, Japan. It describes an entirely warp-knitted lace strip with sinuate scallops and U-shaped picots, made on a raschel machine. Strips are knitted alongside soluble yarn portions (vinylon) that are dissolved in water to separate the units cleanly, replacing hand or machine cutting and basting-yarn removal. The document includes the claims, background, detailed description, and eight sheets of knitting and lapping diagrams, and is supplied as both a USPTO database printout and the patent's printed format.
