Abstract (en)
The present invention relates to a device for making the value of the tension of the thread uniform 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 and along the said axis descends and moves in an essentially concentric position, between the beginning and end of the cop, during unwinding of the wound thread, in order to ensure an essentially constant distance between the descending point of rewinding and the movable element above which, as stated, acts as an unwinding accelerator. <IMAGE>
