The invention relates to continuous yarns low and variable third twist.

Sometimes the yarns are given a considerable twist, ζ ", Β, γ on 2.5 to 12 turns, per centimeter in Yielf filament yarns ₉ and the twisting is carried out by twisting as a separate processing of the yarn, as ββ τοη is made available to the supplier" In last since, however, after there are continuous yarns with redeemed evenness and

This little twist is sufficient to give the yarn adequate compactness and manageability for at least one large rope for subsequent processing

Yarn manufacturers of continuous filament yarns have long known that the use of even a low degree of twist is an obstacle to increasing productivity, and various alternative methods of twisting have been devised and some have been used. Instead of the usual Bingapindelatiiwioklung about when Nylonver "wiri2UÄg used ^1, the alternative methods back a cheese-like winding using a type and hergehendem Querbewe £ u $ gsmschaniemus together with any of the various institutions sur achieve KoMsion" wipe each £ aeden with each other, According to the British patent specification Mr. 401 652, this kind of adhesion between the threads instead of twisting can be achieved by
