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.
