First installment of a 1927 article by Dr. Walther Mevius on applying scientific management (psychotechnics, time study, work planning) to the preparatory departments (Vorwerk) of a mechanical weaving mill. It outlines an analytical part (material standards, machine and worker performance norms, sizing control) and a synthetic part (marking systems, work orders, work distribution). It then describes a model 2000-loom plant with departments for winding and warping, sizing, drawing-in and reed work, and a planning office. Figures show a floor plan and Schlafhorst winding and warping machines.
