Yarn-feeding assembly for textile machines

A yarn-feeding assembly, comprising a first yarn feeder provided with a drum which has a plurality of yarn loops wound thereon and is driven to rotate by a respective motor, said motor being electronically connected to a textile machine for rotating at a speed proportional to the yarn-drawing speed of said textile machine and delivering the yarn wound on the drum to the textile machine, and further comprising a second feeder, which is arranged to draw the yarn from a reel and to deliver it to said first feeder, with a delivery action which is modulated by a control loop which is programmed to stabilize the tension of the yarn unwinding from said second feeder on a predetermined value on the basis of a signal received from a tension sensor operatively coupled to the yarn.
