Formulation of Prediction Model for Optical Film Defects under Transportation by Traction and It's Application to Industrial Problems

卷筒纸处理工艺已被广泛用于许多产品，如液晶显示器、太阳能和燃料电池以及印刷电子领域中相关的其他柔性薄材料。卷筒纸输送行业在输送过程中经常会遇到打滑、打滑等问题。另一方面，由于卷绕过程是生产的最后阶段，这些幅材缺陷已经成为损失大量材料和非常高的生产成本的原因，并且浪费了大量时间来恢复卷绕的卷。辊内滑移和起皱的产生与辊内应力分布密切相关。本文从理论和实验两方面阐明了纸幅处理过程中纸幅缺陷的产生机理，并提出了有效的保护措施，并进行了实验验证。

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.
