Abstract
A yarn tension control system incorporated into a computerized control system of a textile machine for controlling the operation of a fast responding braking or friction device. The braking or friction device is positioned along a weft yarn path and includes a functional control unit operably coupled to the computerized control system, a tension sensing arrangement for sensing the tension of a strand of weft yarn passing therethrough, and a friction force applying arrangement for applying a friction force to the strand of weft yarn in dependence upon the tension sensed by the tension sensing arrangement.
