ABSTRACT:
There is disclosed a thread friction measuring arrangement comprising first and second strain gauges arranged in a thread path either side of a cylindrical surface against which friction is to be measured so that the first and second strain gauges give electrical outputs respectively corresponding to the tension in the thread before and after turning around the surface, and further comprising electronic components for computing the frictional coefficient of the thread in the surface from the electrical outputs.
