Part 3 of Posselt's serial on silk, from the December 1907 issue of Posselt's Textile Journal. It describes a silk doubler and twister with a stop motion (the Tynan machine of Paterson), common defects in thrown silk such as soft twist, kinks and corkscrew, and singles. It then covers reeling silk into skeins, including single-fly and four-fly reeling frames and the registering (measuring) clock that controls skein length. The text is illustrated with mechanical diagrams and photographs of machinery; there are no weaving drafts.
