Abstract
In order to measure tension in a moving web independently of the frictional forces developed between the web and stationary parts of the measuring mechanism, a drag board assembly is provided with a pivotal mounting on an axis which is so located with respect to the loop into which the web is deflected in passing from the adjacent guide roll on the upstream side to the adjacent guide roll downstream thereof that the forces generated by web tension acting on the drag board assembly create a turning moment about its pivot axis which is continuously measured by a load cell or other load sensing means, but whatever moments of force are generated by friction between the web and the drag board assembly are effectively neutralized by directing them through the pivot axis.
