Method for controlling and regulating thread tension of e.g. carpet yarns to predetermined value in yarn refining equipment, involves controlling each of multiple threads by same predetermined tension

摘要

The method involves controlling each of multiple threads (2) by same predetermined tension, which is greater than the tension that is originally present in the threads. The thread tension of each individual thread is determined by using a force sensor (3). The detected thread tension is evaluated by using an electronic unit (4). The thread tension of each individual thread is controlled to a predetermined value by using an electromagnetic thread brake (5). An independent claim is also included for a device for controlling and regulating thread tension of threads.
