16 Claims

1. A method for producing long-term bendable glass material, comprising:

bending a glass material in a bending radius in a range of 1 mm to 10⁷mm; winding said glass material onto a roll, said glass material having a maximum thickness of 500 μm and a minimum thickness of 3 μm; storing said bent glass material for a time period of at least 1 day; inspecting at least a portion of said bent glass material for damage after said storing; and classifying said inspected bent glass material as a reject if damage is detected or as a long-term bendable glass material if no damage is detected.
