In this paper, experiments on preventing wrinkles by using concave rollers compared with cylindrical rollers are described. Wrinkle generation is examined using the following four test rollers: a cylindrical roller with a uniform axial diameter, a cylindrical roller with micro-grooves, a concave roller with a diameter that increases towards the two ends, and a concave roller with micro-grooves. Moreover, the relationship between the use of a concave roller and wrinkle generation is clarified by comparing all experimental results.
