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.

Process for the operation of a bobbin creel and bobbin creel for a winding system

For inserting a dividing cord loop into the opened shed warp on a sectional warping machine, a dividing device has at its disposal an introduction element ( ) with a first, preferably movable guide arm ( ) and a second, preferably stationary guide arm ( ). The free ends ( ) of the two guide arms may preferably be led together in a pincer-like movement. The guide arms are preferably designed as tubes which in the led-together condition form a flow channel. With the help of an air conveyor ( ), from a bobbin chamber ( ) a dividing cord may be drawn off and as a loop be layed around a divided shed warp lying between the two guide arms and by way of a knotting means be connected to a cord loop. The connected cord loop is thereafter by way of a suction device or a blower device positioned and tensioned in a manner such that the cord loop bears at least on one side on the divided shed warp or on the warp web.
