A 1943 German-language technical handbook (Konradin Textil-Betriebsbücher, vol. 25) on producing leno (Dreher) fabrics on power looms and hand looms. It covers leno principles, standing and doup threads, English twine and Swiss flat-steel doup heddles, shaft and let-off/rocker arrangements, and full-leno (Polish leno). Later chapters treat Jacquard leno, needle-bar shafts, Madras curtain and decorative fabrics, charting leno weaves on point paper, and hand-loom methods including the Häkchen (hook) lay and false leno. Illustrated with 128 figures, many of them weaving drafts and mechanism diagrams.
