Long flexible materials such as plastic film and metallic thin film are called web, which are made by Roll to Roll producing system. In this producing method, the web is often wound in the shape ease handling and storage after coating. After that the internal stress of the wound roll will be changed when the wound roll is transported or treated with heat. In this case defects such as slippage or wrinkling will be occurred when the internal stress of a wound roll is changed. This paper describes optimization method of winding tension for preventing the wound roll defects under unstable environmental temperature based on the optimum design technique by Hashimoto. In addition we measured the internal radial stress of a wound roll to verify the effectiveness of the optimum wind-up tension. As a result, we confirmed theoretically and experimentally that the internal stress distributions of the wound roll are improved drastically for preventing both wrinkling and slippage simultaneously by the proposed optimization method.
