Abstract

890,616. Spinning yarns; textile rollers and draw-frames. T.M.M. (RESEARCH) Ltd. Aug. 19, 1960 [Aug. 21, 1959], No. 28732/59. Classes 120(1), 120(2) and 120(3) Yarn is produced by subjecting a card sliver to three drafting passages, packaging the product of the last stage thereof on a conventional speedframe bobbin, the roving so produced being 0À28 hank or coarser (cotton count) with twist factor 0À7 or less, and subjecting such roving on the bobbin to a ring-spinning operation including a draft of at least 40. A speed-frame on which the third draft is effected comprises three pairs of rollers with tension draft only in a first fixed zone and a variable draft in the back zone. The back pair of rollers is positioned to cause upward deflection of the sliver as it passes from a guide at the rear of the drafting system to the middle pair of rollers, and the upper back roller is adjustably set rearwardly of the lower thereof in order to improve fibre control. The draw-frame sliver may be coiled in cans rotating alternately through an angle less than 180 degrees so that two slivers fed side-by-side are coiled in opposite halves of the can, enabling double sliver to be creeled to each spindle of the speed-frame. High draft apparatus at the ring frame may have an initial zone of variable length (draft 4 to 8) an intermediate zone where the roving is constricted in a slightly tapered guide extending between the nip of the drafting roller of the first zone and the holding rollers of the final zone (draft up to 1À25) and a final zone comprising a double-apron unit (draft 30 or more). Specification 851,927 is referred to.
