Folding tester is designed according to national testing standard of paper and cardboard folding endurance. It can automatically count the times of double-folding about specimen. It takes photoelectric control to make folding clamp back after testing. It is convenient for next operation. The instrument has powerfull function of data processing. It can not only convert the double folding times and values of single specimen, but also analyses group specimens data to show maximum, minimum, average and variation coefficient. These data stores in micro-computer displayed by LED. In addition, it has the printing function.
