S1108-3-3 Experimental Study of Defects Prevention Method under Web Transportation

Abstract

Thin, flexible and long materials such as paper, metallic thin film and optical film are called webs. These are the important materials supporting our life. In recent years, the market of the webs is increasing rapidly because of the public demand for Flat Panel Display (FPD), electronic paper and solar cell. Therefore, it is very important to improve the productivity of the web in the manufacturing site. The webs are produced by Roll to Roll producing system, which production method can be continuously produced. On the other hand, the production system may undertake a great loss. Therefore, it is necessary to correctly transport the webs. However, the webs have possibility of defect such as wrinkle and slip because the webs become very thin recently. These defects can be prevented using concave roller. We experimented wrinkle generation using concave roller. As a result, the effectiveness of concave roller is verified experimentally.
