| Research Abstract |
The web handling processes have been widely used for a lot of products, such as liquid crystal display monitors, solar and fuel cells, and other flexible thin materials related in the printed electronics fields. Most of web handling industries are often encountered with the problems of wrinkling and slippage in the transportation process. On the other hand, since the winding process is a final stage of the production, these web defects had been a cause of losing a lot of materials and being very high production costs, and wasting a lot of time to restore the wound roll. The generation of wrinkling and slippage in the wound roll is strongly related with the in-roll stress distributions in the wound roll. In this research work, the generation mechanism of these web defects in the web handling process was clarified theoretically and experimentally, and the effective methods to protect such defects were proposed with experimental verifications.
