  • Process for the operation of a bobbin creel and bobbin creel for a winding system
    Patent number: 6513748
    Abstract: At least one thread tension sensor for each thread is provided on a winding machine. The actual value of thread tension is measured for each thread. The actual value is compared with a specified value in a comparator device and, in the event of a deviation being determined between the actual value and the specified value, a drive motor is actuated to adjust the thread brake of the thread concerned. This arrangement allows for the maintaining of a constant thread tension by a control circuit. The thread tension sensor can be used not only to control the thread tension, but also to monitor the specified thread tension range, and as a thread break monitor.
