A web is continuous flexible materials such as paper, plastic film, thin metal plates etc. Before being converted to the final product, the web undergoes several processes, for example, transportation by the drag roller, press, printing, coating, drying, slittering, winding, and so on. Under such processes, the web is given the additional values to enhance the quality and function of product. When the web defects, such as slippage, wrinkling, star defect and telescope, are generated in the web handling processes, the web defects immediately result in quality loss. Therefore, to predict and protect the web defects is very important engineering problems in web handling industries. This key note paper describes the recent research topics treating how to predict and protect the web defects based on the theoretical model with experimental verifications.
