Abstract

The device 18 comprises a set of fixed bars 19 which are equally spaced apart and a set of moving bars 20 which are spaced apart in the same way alternating with the fixed bars and supported by moving equipment 25 provided with an excitation coil 30 subjected to a permanent magnetic field 27. The yarn runs between the fixed and moving bars and is partly wound onto them forming winding angles α which vary in relation to the movements of the moving bars with respect to the fixed bars produced by corresponding movements of the said moving equipment. The mechanical tension in the yarn on leaving the device is an increasing function of the said winding angles. <IMAGE>
