Abstract

1,165,271. Interlacing filaments to form yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 13 June, 1968 [11 July, 1967], No. 31895/67. Addition to 1135486. Heading D1F. The specification relates to a modification of the process claimed in Specification 1,135,486. The present process consists in pasing two twistless multifilament bundles Y 1 , Y 2 , from adjacent positions on a machine for processing running yarns, at least once around one or more loop-forming members 11 in such manner as to intertwine with each other in the overall configuration of a reef-knot whereby the filaments in each yarn are intermingled, and then collecting the so compacted yarns separately in an orderly manner. The loop-forming members 11 are preferably closely-spaced ceramic pins. The intertwinement may take place between the draw rolls and balloon guides of a drawtwisting machine. Alternatively the intertwinement may take place upstream of the traverse guides of the wind-ups of a melt-spinning extrusion machine.
