Abstract (en)
[origin: EP1577246A1] The feeder comprises a stationary cylinder (12) supporting a plurality of yarn loops (RT) wound helically along its outer skirt. A finger (28) with a magnet (38) incorporated therein is mounted in an elastically yielding way along the skirt of the cylinder under the pressure of the yarn wound on the cylinder, to be biased from a first position projecting outside the skirt, to a second, inner position, and vice versa. A sensor (40) is supported in front of the magnet (38) in a stationary position relative to the cylinder to generate an output signal (U) proportional to the distance between the magnet and the sensor.
