Abstract:

We evaluate the known solutions regarding the tensioning of yarn in the operations of winding, warping, doubling, etc. The conventional tensioners that have so far been used in the textile industry are described and analysed. We present our own original design for a frictional electromagnetic tensioner in which the nipping load, applied to several ferromagnetic, flexibly inter-coupled nip plates (barriers) is induced by the poles of an electromagnet. Under each barrier (nip plate), the thread or yarn is imparted with part of the tension gain. Tests in which the practical operating performance of the electromagnetic tensioner was compared with that of the conventional disk and compensating tensioners showed that the electromagnetic tensioner was significantly superior.
