Direct measurement of threadline tension between a rotating ring traveler and the point of enrollment on the package surface is difficult because of the general inaccessibility of this portion of the threadline. Despite this limitation, at least four methods for deducing yarn tension by measurement of winding moment have been described. A novel, but simple system for measurement of winding tension is here described in which variation in electrical load on a twisting spindle drive motor provides the means for measurement of winding moment.
