Part I of a German-language handbook for loom overseers (Webmeister) on the plain narrow high-speed power loom, in its second revised and enlarged edition (1926). It describes the loom's parts and their assembly and adjustment: warp beam and brake, cloth beam and take-up, regulator and change-gear tables, shed formation with cam construction for inside and outside treadles, counterbalance devices, lay arm, shuttle box, picking, stop motions and warp-protector mechanisms. A second section lists causes of faulty cloth and loom breakdowns, and a third covers mechanics and calculations (levers, wedge, belt drive, gears) and the weaving master's tools. Illustrated with 58 line figures and many calculation tables.
