Abstract

L'invention concerne un procédé et un dispositif de texturation d'un fil synthétique, selon lequel le fil est prélevé d'une bobine d'alimentation et transporté à une vitesse de fourniture jusqu'à une zone de texturation. Une ondulation est produite sur le fil à l'intérieur de la zone de texturation, le fil étant tiré de la zone de texturation à une deuxième vitesse de fourniture, de telle sorte que le fil est étiré par un banc d'étirage avec un rapport d'étirage produit par les vitesses de fourniture. L'invention vise à pouvoir produire avec le fil des effets dans un tissu coloré. Pour ce faire, le rapport d'étirage selon l'invention est modifié, pour étirer le fil, par une augmentation ou une diminution d'une des vitesses de fourniture dans un ou plusieurs intervalles de temps de fonctionnement.
