A dictionary entry on the drawing-frame, the spinning-preparation machine that elongates and straightens carded slivers of cotton or wool by passing them through successive roller pairs running at increasing speeds. It covers the machine's history (Lewis Paul, Arkwright), roller construction, the doubling process with a worked example, and the variants for long-staple wool and for silk waste. One diagram (Fig. 1751) shows the rollers, cans, funnel and compacting rollers.
