An International Textbook Co. instruction paper (section 49, Part 1) on preparing woolen and worsted warps. It introduces the four warp preparation processes (spooling, dressing, beaming, drawing in and reeding), then covers spooling in detail: the ordinary spooler, bobbin stand and worsted creel, tension rolls, traverse motion, spool-holding device, yardage measuring motion with bell, and stop-motion. It also describes the compressing spooler with its grooved compressing roll, slow motion and stop-motion. It closes with examination questions, some with numeric answers on yardage, yarn weight and piece-rate wages.
