Abstract
A method for determining bending stiffness of a moving sheet using an on-line sheet bending stiffness sensor. The sensor continuously bends the sheet as it is being manufactured and, based upon the force required to bend the sheet, the amount of bending and the tension applied to the sheet, the sensor determines a parameter indicative of sheet bending stiffness. The resulting parameter can be correlated with conventional destructive laboratory tests of sheet bending stiffness.
