The alignment of the rollers carrying the web is found to be one of important factors to the lateral behavior of the moving web and to the quality of the final web products. But, the perfect alignment of the rollers is not always possible and the web itself can be cambered. Thus the control of lateral behavior of the moving web is critical in the most of web handling systems. The web guiding system that adjusts the angle of the alignment between two adjacent rollers is commonly used in industry. But, in this paper a new web guiding system is proposed by using the lateral dynamics of the moving web induced by a tilted roller in normal direction of a web. The computer simulation study was carried out to verify the steering performance of the suggested guiding system. Computer simulation study shows that the performance of the new guiding mechanism is better than that of an existing guiding mechanism.
