Abstract

A device for measuring bending strength of a sheet material in a predetermined direction is disclosed. The device has a clamp, a load sensor, a revolving unit, a data-processing unit, and a data-displaying unit. The clamp has a tip that extends in a direction perpendicular to the predetermined direction and holds one end portion of the sheet material. The load sensor is positioned relatively below the other end portion of the sheet material being held by the clamp. The revolving unit for revolving the clamp is provided on one end in the direction along the tip of the clamp. The data-processing unit for storing the resistance force to be detected by the load sensor by contacting with the sheet material during a period of revolving the clamp and information concerning the position of the clamp traveled by the revolving unit, by which stored data is processed and outputted as output data in a predetermined form. Furthermore, the data-displaying unit displays the output data.
