A short German-language technical report from 1927 on the Ferrand high-draft drafting system for spinning machinery, made by the Universal Ring Spindle Co. of Manchester. It explains how three vertically arranged roller pairs let the roving go straight into the ring frame's drafting unit, which removes the intermediate and fine roving frames. It covers claimed savings in labor, power and waste, and use with cotton, wool, asbestos and cotton-wool blends. Photographs and a line drawing illustrate the machine.
