A short trade article from The Melliand Textile Monthly (July 1931) describing a new patent ring spinning frame for woolen and blended yarns, built by Platt Brothers & Co., Oldham, England, following research by the British Research Association for the Woolen and Worsted Industries. It explains the changes from earlier models (heavier top rollers, Carborundum-covered rollers, new false twist tube, tension regulator, brake roller) and the threading path of the yarn. It reports claimed advantages over mule spinning: high drafts, spinning up to 70 skeins in woolen counts, larger output per spindle, more level yarn, about 75% floor space saving, and power requirements. Includes a photograph of the frame.
