Abstract

1318413 Plied yarn COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION 5 June 1970 [17 June 1969] 27327/70 Headings D1F and D1W In the production of a uniform yarn from at least two running strands, the strands 7, 8 are separately fed from a feeding point to a convergence point 10, the rates of feed being substantially equal, the strands are twisted together at the convergence point 10, and at the same time the path length between the convergence point and the feeding points is cyclically varied. In a preferred embodiment the strands 7, 8 are fed from drafting rollers 1 which are placed symmetrically about a plane containing the axis of the convergence guide 10. The converged strands are fed through a guide 2 to be twisted on to a package on a ring spinning frame. The convergence guide 10 is caused to move cyclically between a point X in the aforementioned plane and the original point Y. The convergence guide 10 may be in the form of a suction tube with a birfurcated end, forming a slot for the strands, -the bifurcated end being caused to oscillate by means of a cam arrangement. In an alternative arrangement, the convergence point is caused to vary cyclically by means of reciprocating guides which move perpendicularly towards and away from the aforementioned axis. A number of pairs of drafting rollers and associated convergence guides &c may be arranged side-by-side, separator plates being positioned between adjacent pairs. The yarn of the present invention comprises at least two strands twisted together with plying twist which varies cyclically in intensity along the length of the yarn, and in which each strand is twisted with an alternating twist. The regions of like twist in the strands are in phase with one another in the plied structure. The regions of high intensity twist in the plied structure coincide with. regions in the strands which are of opposite twist to the plying twist.
