ABSTRACT:
A web tension load cell for a paper mill and the like wherein the load cell is mounted in a member which can flex due to a metal flexture point that eliminates mechanical back lash such as occur with ball or roller bearings. As the load on a roller varies flexture will occur at the metal flexture point which will transfer a load onto the load cell which is detected and converted into a signal for controlling a tension control that varies the tension on the roller. Top and bottom plates and the load cell are designed so as to maximize the structural stiffness to optimize the mechanical stiffness and mechanical vibration frequencies of high speed winders utilized in paper mills.
