YARN SPINNING

摘要

A yarn (8) is spun by dividing (20) a travelling fibre assembly into a plurality of fibre sub-assemblies (9a, 9b), causing the sub-assemblies to traverse different paths and then recombining them (30), wherein the paths are sufficiently proximate for fibres to continuously transfer from one or more of the sub-assemblies and be drawn onto or into another or other sub-assemblies. Also disclosed is a method for forming a yarn comprising twisting a plurality of fibre sub-assemblies together at a convergence point (30) to form a fibre assembly being a yarn (9), and further including cyclically altering the relative twist propagation in and/or into the sub-assemblies upstream of the convergence point (30). Still further disclosed are alternative methods involving cyclic variation of paths traversed by the sub-assemblies, and cyclic alteration of the relative positions of the sub-assemblies. Apparatus is described for carrying out each method.
