Yarn package offtake performance monitoring
 The invention provides a method of monitoring yarn package offtake performance comprising withdrawing yarn from a package, for a predetermined period of time continuously measuring the tension of said yarn at predetermined time intervals throughout said withdrawal and updating the obtained tension distribution data with each tension measurement. The method also includes noting the maximum and minimum tensions measured and the limiting values of a range of tensions outside which range only a predetermined proportion of said measured tensions fall, and determining an offtake performance factor from said maximum, minimum and limiting values of tensions.
