CA 2194843

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 texturising nozzle 5 are separated again into crimped part-threads 11.3 through 11.5 and according to the invention are compacted in after-compacting means 8 before these part-threads are jointly compacted in a collective compacting means 9 and subsequently 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 further elements 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 false twist means. Both means are known from earlier descriptions already.

Dans la fig. 1, appareil connu comme tel pour produire un fil multicolore, sauf que les fils composants 11, 11.1 et 11.2, après avoir été texturés dans un ajutage de texturation 5, sont de nouveaux séparés en fils composants frisés 11.3 à 11.5 et, selon l'invention, sont compactés dans un module de post-compactage 8 avant que ces fils composants soient compactés ensemble dans un module de compactage collectif 9 et subséquemment bobinés pour former un fil résultant 12 dans un bobinoir 10. Les éléments constitutifs en cause sont brièvement décrits comme des arbres de refroidissement 1, des applicateurs de fini 2, des modules de pré-compactage (3) et des cylindres d'étirage 4. Les autres éléments ont été décrits précédemment. Les applicateurs de fini 2 sont en général des applicateurs d'huile et les modules de compactage 3, 8 et 9 respectivement sont des modules d'enchevêtrement ou de fausse torsion. Les deux types de module sont connus pour avoir déjà été décrits précédemment.
