A web is thin and flexible materials such as paper, optical film, metallic lamina etc. In recent years, the web is expected fusion with printed electronics. The web is produced by Roll to Roll producing system with high productivity. However, when web defects are occurred in the producing processes, the web defects result in waning productivity. It is known that the web defects can be prevented using specially shaped rollers. Among them, a concaved roller which has large edge diameter compared with center diameter can be made by easy process. Therefore, most of engineers empirically use concave roller. However, when engineers mistake roller geometry and use, web defects might be caused oppositely. Therefore, to understand the preventing mechanism and effect is very important for web handling engineers. This paper describes the spreading mechanism and effect by concaved roller. The spreading effect of concaved roller is measured by slit separation of web. As a result, concaved rollers were confirmed that these separated web. Consequently, concaved rollers showed that there was an effect of web spreading. In addition concaved roller with micro-groove showed slit separation of web under low tension.
