Folding Test Machine

Abstract

A folding test machine to measure the durability against folding can be operated by minor adjustment even if a radius of curvature of the folding or an arc length of the folding is changed. A fixed wall and a moveable wall are opposingly provided in an approximately box-shaped frame and a holding part to hold a workpiece is provided on the top of each of the fixed wall and the moveable wall in a rotatable manner in a vertical plane of the rotation. And the workpiece and a plate spring are held on the respective opposing end portions so as to be bridged between the fixed wall and the moveable wall in a curved manner such that the moveable wall is moved closer to and farther from the fixed wall repeatedly such that the work is folded repeatedly.

Dependencies are inferred from the claim text.
