Abstract (en)
The present invention relates to a device for adjusting the tension of the thread as it unwinds in a spooler, which is designed to wind thread at high speed, the said device comprising a movable element (1), which acts as an unwinding accelerator and which at the tip surrounds the axis of the cop (3) and along the said axis descends and moves in an essentially concentric position during unwinding of the wound thread. The said movement is activated by a kinematic mechanism moved by a drive source (8) operated by the electrical signals from a tension sensor (9) which measures, moment by moment, the tension of the thread, which travels to be transferred from the cop (3) below to the reel (14) above being wound. <IMAGE>
