A 1930 trade-journal article by M. G. Berg describing a penalty system for controlling the quality of knitting in a hosiery mill. It explains how leg and foot examining departments inspect production, collect replacement and penalty legs or footed stockings from knitters, and route good and bad work through storage and menders. Punched-coupon cardboard forms (Figures A to G) provide weekly records, payroll data, and analysis of the causes of bad work.
