METHOD AND APPARATUS FOR PRODUCING A MULTICOLOURED YARN FROM DIFFERENTLY COLOURED PART-THREADS OF ENDLESS FILAMENT

摘要

In the Fig. 1 an apparatus known as such for producing amulticoloured yarn except that the part-threads 11, 11.1 and 11.2 after texturisingin a texturising nozzle 5 are separated again into crimped part-threads 11.3through 11.5 and according to the invention are compacted in after-compactingmeans 8 before these part-threads are jointly compacted in a collectivecompacting means 9 and subsequently are wound up as a yarn 12 in a windingdevice 10. The individual elements concerned are briefly described as coolingshafts 1, finish applicator means 2, pre-compacting means 3 and draw rolls 4.The further elements have been described earlier. The finish applicator means 2as a rule are oil applicator means, and the compacting means 3, or 8 or 9respectively, are either entanglement means or false twist means. Both meansare known from earlier descriptions already.
