Third installment of Fritz Keunecke's series on machine-made fancy laces, covering the influence of friction on thread tension in lace-machine carriers. It derives rope-friction formulas and reports experiments with a spring scale and a rotating-pulley rig on cotton, luster cotton and rayon yarns with steel and glass eyelets. It then compares tension-weight carriers with tension-spring carriers and discusses the effect of periodic stopping and starting on the one-thread lace machine. The text is mathematical and experimental, with many graphs, tables and apparatus diagrams.
