Patent abstract
A method for measuring the rigidity of paper or other products made from cellulose fibers wherein the paper is torn and a digitized sound recording is made during the tearing process which is then analyzed to determine the percentage of time during which characteristic frequencies are present during the tearing process. It has been found that this percentage correlates well with rigidity.
