A technical treatise on Jacquard machines and their accessories, covering harness ties (straight-through, repeating, centre and mixed ties), the preparation of Jacquard cards, and the machines that cut, lace, stitch and repeat them. It covers hand and power card-cutting, reading boards, hand and mechanical lacing, peg- and lace-hole machines, and ordinary-, medium- and fine-pitch repeating machines. It is heavily illustrated with mechanical line drawings and photographs, plus some design and harness diagrams and a few weave-strip drafts. The volume also has a subject index and period advertisements from Jacquard and loom makers.
