Abstract (en)
[origin: EP2754742A1] A first yarn feeder (14) is provided with a drum (16) which has a plurality of yarn loops (Y) wound thereon and is driven to rotate by a respective motor (20). The motor (20) is electronically connected to a textile machine (12) for rotating at a speed proportional to the yarn-drawing speed of the textile machine and delivering the yarn wound on the drum (16) to the latter. A second feeder (22) is arranged to draw the yarn from a reel (18) and to deliver it to the first feeder (14), with a delivery action which is modulated by a control loop (24). The latter is programmed to stabilize the tension of the yarn unwinding from the second feeder on a predetermined value on the basis of a signal received from a tension sensor (26) operatively coupled to the yarn.
