Part 2 of an International Correspondence Schools textbook on chain warping for cotton and similar mills. It describes the construction and operation of the Denn warper: creels, mechanical and electrical stop-motions, leasing harnesses (thread and pin leases), measuring rolls, the linker head, balling attachments and the measuring motion with gear calculations. It also covers chain weight calculations, Walcott warpers, Entwistle-type long-chain beaming machines, and quilling machines, ending with notes on oiling, cleaning and care of the machines. Illustrated with many mechanical line drawings.
