ABSTRACT:
A device for measuring the tension of a traveling yarn, comprising two spaced-apart stationary yarn guide elements defining a yarn travel path therebetween and a measuring member disposed between the yarn guide elements and projecting into the yarn travel path to engage the yarn and react to tension changes therein. Each of the stationary guide elements has a yarn guide groove, and the movable measuring member comprises a yarn engagement body extending linearly in a direction substantially perpendicular to the yarn travel path. The yarn engagement body includes a central area with a yarn guide contour essentially convexly rounded in the direction of the yarn travel path and merging at opposite lateral ends of the central area with end areas essentially convexly rounded both in the direction of the yarn travel path and substantially perpendicular thereto.
