Abstract

In monitoring the yarn tension at each of a plurality of yarn processing stations, the mean value of the monitored tension is continuously determined at each station, and the differential between the monitored value and the mean value is also continuously determined. In addition, an overall mean value is generated which is representative of an average of the mean value signals from all of the individual stations, and the overall mean value is compared with the individual mean value of each station. In the event the mean value signal at a particular station differs from the overall mean value signal by more than a predetermined tolerance limit, an alarm signal is generated.
