  • Patent number: 11047783
    Abstract: The present invention relates to a folding apparatus for flexible material durability testing, the folding apparatus including: a material fixing part fixing a part of a flexible material to be tested; a pivoting plate spaced apart at a predetermined gap from the material fixing part, and folding or unfolding the flexible material by rotatively moving in a state where the other part of the flexible material is fixed thereon; and a motion controller supporting the pivoting plate to enforce the pivoting plate to rotatively move and to allow the pivoting plate to forwardly or backwardly move with respect to the material fixing part at the same time. In addition, because a miscellaneous force in addition to tensile force is not applied to the material during flexible material durability testing, the testing is highly reliable. Accordingly, the folding apparatus may accurately perform the flexible material durability testing.
