Abstract

632,697. Making slivers, rovings and yarns of stapled fibres. POOL, W., and McGILL, A. April 30, 1947, No. 11620. [Classes 120 (i), 120 (ii) and 120 (iii)] A process for the conversion of a bundle of continuous filaments into a continuous product made of staple fibres comprises gripping the filaments of the bundle at two spaced points, forwarding the gripped filaments from the first of said points towards the second at one linear speed and from the second point onwards at a greater linear speed so as to stretch the filaments between the two points, and at a third point, between the two points subjecting the filaments to sharp and rapidly repeated impact so as to break, at said third point, some of the filaments that have been stretched to a degree substantially short of that at which they would break under tension. Slivers 1 from cans 3 are led to flattening bars 7 and thence between tensioning roller sets 8, 9, 10. Between roller pairs 12, 13, 19, 20, which may include leather &c. belts 16, 21, the flattened sliver is subjected to a " draft of 5 or more and while tensioned below its breaking point, is subjected to impact by a straight edge 26 vibrating at 2,000 oscillations or more per min. The impacts break the filaments of the sliver and form a continuous stapled product which is subject to a false twisting device at 30 and lubrication at 31. After passing through a further false twisting device 38 and a "stuffing- box," the crimped sliver is collected in a rotating coiler can 44. In a modification, the stapled sliver is fed by rollers from the false twister direct to a flyer for winding it on a bobbin as a roving. In a further modification, the stapled product is fed direct to a ring spinner for winding on a bobbin as a coarse yarn. Specification 582,949 is referred to.
