Slipping or wrinkling of web is serious -problems in web handling system such as a paper engineering manufacture machine, a print machine etc. These phenomena in web handling are called web-defects and have the possibility that has given a fatal defect to a product. Elucidating mechanism of various kinds of web-defects and preventing it beforehand is an important technology problem. This paper describes a theoretical prediction model of friction coefficient between uncoated paper and steel roller and outbreak condition of web wrinkling. It is cleared that the friction coefficient between web and roller and outbreak condition of web wrinkling receive influence of parameters such as web tension, web width, web wrap angle and roller radius. Then the relation of friction coefficient and outbreak condition of web wrinkling is trade o f and the prevention of slipping and wrinkling of web simultaneously by adjusting a few parameters is difficult. So using these theoretical models and the optimum design technique, each parameter was optimized.
