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 a multicoloured yarn, ex-cept that the part-threads 11, 11.1 and 11.2 after texturising in a texturisingnozzle 5 are separated again into crimped part-threads 11.3 through 11.5 andaccording to the invention are compacted in after-compacting means 8 beforethese part-threads are jointly compacted in a collective compacting means 9 andsubsequently are wound up as a yarn 12 in a winding device 10.The individual elements concerned are briefly described as cooling shafts 1, fin-ish applicator means 2, pre-compacting means 3 and draw rolls 4. The furtherelements have been described earlier.The finish applicator means 2 as a rule are oil applicator means, and the com-pacting means 3, or 8 or 9 respectively, are either entanglement means or falsetwist means. Both means are known from earlier descriptions already.
