Abstract

Yarn processing system for simultaneously processing a plurality of yarns in a processing machine, such as a twisting machine, a texturizing machine, or a dyeing machine. A yarn tensioning assembly is provided and has, for each yarn entering the processing machine, at least an individual controlled tensioner and an individual tensiometer. The controlled tensioner and the tensiometer are integrated into a closed yarn tension feedback regulation loop for regulating and maintaining a set yarn tension. The tensiometer is connected in parallel to one superimposed common tension monitoring and setting system for centrally setting and monitoring the yarn tension.
