Abstract: The system to control the winding of yarn on to a bobbin uses a tension sensor to give a periodic measurement of the yarn tension to be compared with a pre-set value which is either constant or proportional to the increasing dia. of the bobbin, so that the rotary speed of the bobbin can be controlled throughout the winding operation. The system gives a continuing monitoring action on the yarn without imposing friction which could lead to abrasive damage of the yarn, and without requiring complex mechanical components to register yarn tension.
