Abstract
The distribution of tension in flat products is measured by a bendable roll engaged by segmented rolls. The bendable roll has a peripheral surface which engages the width of workpiece and is elastically bendable along its axis under the tension in the workpiece. The elastic deformation of the solid roll exerts loads on the segmented rolls and one or more sensors detect the transmitted loads.
