Abstract (en)

[origin: EP2186932A1] Yarn loops are unwound from a yarn feeder (18) provided with a stationary yarn-winding drum (20) upon request from a textile machine (16). Braking means (28, 128) apply a braking action by friction on the unwinding yarn in such a way as to maintain the yarn tension substantially constant. A yarn consumption sensor (34) continuously measures the actual yarn consumption and generates a corresponding signal (PS) indicative of the consumption. Processing means (32, 36) calculate a consumption signal (YC) on the basis of the corresponding signal (PS), compare it with a predetermined consumption range, and adjust the stitches as a function of the difference between the two values.
