This tester is used for determining the folding endurance strength of paper and paperboards. The specimen is clamped by upper and lower grips. Exert the specified load onto the upper grip to have the specimen bear a certain tension. The specimen is vertically placed against the ground surface and is folded to two sides by lower grip. Record the numbers of folding after the specimen breaks.
