Web is an extremely thin and continuous material used for covering film, liquid-crystal-display, etc. In recent years, web is in the spotlight as its potential to combine with advanced technology. Web will be adapted, for instance, fuel-cell, film-based-solar-cell and flexible-display such as printed electronics. Wrinkle, which is plastic deformation of web due to the misalignment of roller supporting web, makes losses of production. Some research has been studied about prevention of wrinkle with spreading roller. One of the most famous spreading rollers is concave roller: it has the maximized edges and the minimized center of its diameter to have a curved line on its shape. This paper shows the result of spreading effects under changing diameter difference of concave roller. The spreading effect is measured by the slit distance on the web on the concave roller. The slit is given by knife at the upper concave roller. The result shows the spreading effect increased with increase of the diameter difference of concave roller.
