ABSTRACT:
A sensor for sensing a quality of paper related to elastic modulus and bending stiffness as it is being made including a paper support in the form of a ring and a free running wheel, which depresses the paper in the center of the ring as the paper passes over it. A force transducer mounted to the wheel senses the force of the deflected paper on the wheel and provides a measure of a characteristics of the paper related to its elastic modulus and bending stiffness. This factor, together with basis weight, thickness and paper velocity are used to determine the strength of the paper on a continuous basis.
