Paper, optical film and metallic thin film are called web. In the manufacturing fields of web, web is supported and transported by a lot of rollers and guides. In such transported situation, the air flow into between web and roller or web and guide with web moving, and then web is lifted slightly by the air. This is the reason of slippage. 1b protect the slippage, a micro-grooved roller is used in manufacturing fields. However how protect the slippage utilizing a micro-grooved roller and what shape and dimension is the best are not known. This paper describes experimental results of slippage onset conditions between optical film and different three rollers, and compared with theoretical prediction.
