Abstract
A device for regulating the length of thread absrobed by a knitting machine and/or for correcting the variations in tension of a thread supplying a textile machine, is disclosed. The device comprises a tensioning means of any type, a drive member whose rotation results in the movement of the tension-generating member of the tensioning means, a feeler element over which the thread passes and which is moved when the length of thread absorbed and/or the tension of the thread varies and two switches, one controlling the placing in rotation of the drive member in one direction and the other the placing in rotation in the other direction. The direction of rotation of the drive member is selected so that the corelative action of the feeler corrects the variation in the length of thread absorbed and/or of the tension which is the cause of triggering this rotation.
