Abstract
A method and apparatus for monitoring the yarn tension at each of a plurality of yarn processing stations is disclosed and wherein 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. A first alarm signal is generated whenever the mean value leaves a predetermined tolerance range, and a second alarm signal is generated whenever the differential value leaves a second predetermined tolerance range. These alarm signals are logged, in both number and duration, to provide an indication of the quality of the yarn.
