ABSTRACT:
The yarn tension at each of a plurality of yarn processing stations is continuously monitored, while continuously determining the mean value of the monitored tension at each station, and while also continuously determining the differential between the monitored value and the mean value. Also, an alarm signal is generated whenever the mean value leaves a predetermined tolerance range, and whenever the differential value leaves a second predetermined tolerance range. An alarm signal may serve to actuate a visual error indicator, or to shut down the associated processing station.
