Yarn tension monitoring and setting system
First Claim
1. A yarn processing system for simultaneously processing a plurality of yarns, said system comprising:
- a yarn processing machine configured for one of twisting, texturizing and dyeing each yarn of the plurality of yarns, said yarn processing machine defining respective yarn channels for each yarn of the plurality of yarns and including a machine control system;
a plurality of rapier or projectile yarn feeding devices each configured for use with a rapier or a projectile weaving machine, each said yarn feeding device including a stationary storage drum, a rotatably-driven winding element and an electronic speed control, each said yarn feeding device corresponding to one yarn of the plurality of yarns entering said yarn processing machine;
a yarn tensioning assembly for generating and maintaining a predetermined yarn tension, said yarn tensioning assembly including a plurality of closed yarn tension feedback regulation loops each corresponding to one yarn of the plurality of yarns entering said yarn processing machine, each said loop including one of said electronic speed controls, an individually controlled tensioner, an individual tensiometer and a regulator for regulating and maintaining a set yarn tension in each yarn; and
a tension monitoring and setting system common for all of said yarn feeding devices for centrally setting and monitoring the yarn tension in each yarn, said tensiometers being connected in parallel to said tension monitoring and setting system.

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.

- 12. A yarn processing system for simultaneously processing a plurality of yarns in respective yarn channels of a processing machine for twisting, texturizing or dyeing the yarns, said system comprising a yarn tensioning assembly for generating and maintaining a predetermined yarn tension, wherein for each yarn entering said processing machine at least an individual controlled tensioner and an individual tensiometer are provided, said tensioner and said tensiometer for a respective yarn are integrated into a closed yarn tension feedback regulation loop for regulating and maintaining a set yarn tension, and at least said tensiometer is connected in parallel to at least one superimposed common tension monitoring and setting system for centrally setting and monitoring the yarn tension in each yarn, said tensiometer including a flexible element comprising a flexible printed circuit, said printed circuit being fixed at one end and loaded at an opposite end by the yarn, said flexible element carrying at least one sensor element and being partly coated with highly flexible temperature and wear resistant material.
