Clark stiffness tester (motorized type) No.2047

Paper stiffness is one of essential characteristics. Newspaper and printing paper must have a stiffness enabling proper handling. This machine measures the stiffness of papers, fibers and films. Typical specimens are papers of small basis weight such as newspaper and thin paper. Stiffness is determined from the flexing load of the specimen. The length of specimen portion extending from the rolls is measured, when the deflection angle of the specimen from one side to the other becomes 90 degrees. Based on this length (critical length), Clark stiffness is obtained.
