The present invention relates to a device for reducing the value of the unwinding tension 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 concentrically to place itself in a lower position corresponding to a reduced minimum quantity of wound thread on the end part of the unwinding cop. <IMAGE>
