Abstract
The device comprises an interchangeable hub 1 fixed inside a tube 2 on which the reel of yarn 3 to unwind is wound. A torsion component 15 is arranged coaxially to this hub 1, is preloadable with a given tension and collaborates with braking components 5, 22. The preload of this torsion component 15 is obtained by varying the angular position of one of its ends 15' with respect to the angular position of the bushing 12 which immediately precedes the axial inlet 13 of the yarn in the reel. The unwinding of the yarn from the reel, by the combined action of these components, takes place with a constant tension value whatever its diameter. <IMAGE>
