Abstract

Disclosed is an apparatus for equilibrating component tensions in a multicomponent filamentary yarn which is advancing in a primary direction. The apparatus includes a series of yarn guides arranged so that the multicomponent filamentary yarn deviates both horizontally and vertically from the primary direction. This deviation advantageously prevents predominance of one component in an air entangled yarn made from two or more different colored or different dye affinity bulked continuous filament feed yarns without unsuitably increasing the overall tension.
The apparatus exploits the surprising discovery that components themselves, with appropriate manipulations, can be used cooperatively to equalize tensions. One aspect of this discovery guides the components to run nearly immediately on top of each other so that they travel in unison.
