摘要： An apparatus for measuring the flexural stiffness of a moving laminar-shaped material web is disclosed that guides the material web over two stationary guide rollers and a deflecting roller. The deflecting roller rides on the material web and deflects the material web for a predetermined distance. A force-measuring device attached to the deflecting roller measures the force exerted by the material web. An actuator movably attached to the force-measuring device is actuated periodically to move the deflecting roller into the material web whereby the force related to the additional periodic deflection is measured by the force-measuring device and evaluated to determine the flexural stiffness of the material web. In a second embodiment of the present invention, the actuator is not used and the deflecting roller includes an eccentric cross-section which imparts on the material web a periodic deflection of the web.
