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.

Part II of Franz Kraus's German textbook for loom overseers in mechanical weaving, covering narrow multi-shuttle looms (Wechselstühle). It describes drop-box (Hubkasten) and revolver box-motion mechanisms by system (Hacking, Eccles, Hodgson, Knowles, Honegger, Hohlbaum), with line diagrams. It explains how to set up shuttle change orders and build pattern cards from weft patterns, lists causes of faulty cloth and loom breakdowns, and closes with a section on mechanics and calculations (levers, wedges, screws, belt and gear drives) and the overseer's tools.

Part III of Franz Kraus's textbook for weaving-mill foremen (second revised and enlarged edition, 1926), covering dobby (shaft) machines and Jacquard machines for power looms. It describes machine components, setting-up, single-lift and double-lift dobby and Jacquard systems (Dickinson, Burnley, Hattersley & Smith, Devoge, Verdol and others), card lacing and punching, and chain-change devices. The Jacquard sections cover cord board calculation, straight-through and point (Spitz) harness tie-ups in German and English systems, mixed tie-ups, lifting cards (Aushebekarte), and troubleshooting. About 100 text figures are mostly mechanical line drawings, with a few weave and pattern diagrams.

Part IV of Franz Kraus's German-language handbook for mechanical weaving foremen, covering the loom setups and attachments needed for special fabrics. It treats light and heavy cloths, double cloths, striped and checked goods, rips, piqué, matelassé, moiré, lancé and brocaded fabrics, pile fabrics (velvet, plush, chenille, loop), damask and half-damask rigs on Jacquard machines, openwork and leno (Dreher) fabrics with their drafts, selvedges, bead and feather fabrics. Illustrated with mechanical diagrams of regulators, shedding and Jacquard mechanisms, plus weave drafts for leno structures.
