Abstract
The present invention relates to a device for correcting the variation in tension of the thread as it unwinds in a spooler, which is designed to wind thread at high speed. The device comprises two elements which act as unwinding accelerators, one fixedly located above the top of the cop. The moveable element pivots between an inoperative position spaced apart from the cop and an operative position coaxial and surrounding the cop so as to place itself concentrically to the cop and in a lower position at the moment when there is a reduced minimum quantity of wound thread on the end part of the cop being gradually unwound.
