A one-page installment from a series on French worsted spinning by Leon Faux, describing the M. G. B. intersecting gill box used in worsted drawing. It covers the fallers' dimensions, pin placement, working zone, screw pitch, trumpet drive and automatic oiling, and also the Martinot and Galland can gill box that lays sliver in spirals in the can. Three technical diagrams (Figs. 108-110) illustrate the machines.
