Abstract

In the yarn tension regulating device for knitting machines in which the yarn (25) runs through a yarn tension sensor (24) and a yarn brake (20) automatically adjustable in dependence upon the indication of the yarn tension sensor, there is located directly in front of the automatically adjustable yarn brake (20), in the direction of travel of the yarn, a yarn forwarding device, in particular a yarn storage feeder (13), by which the tension imparted to the yarn on its path from the yarn spool to the yarn brake is relieved. Between the yarn brake (20) and the yarn tension sensor (24), which follows it in the direction of movement of the yarn, is located a known yarn take-up (21), whereby the automatically adjustable brake (20) constitutes the yarn brake usually provided for this yarn take-up.
