Abstract
The present invention relates to a film wrinkle removing roller in which pattern rolls coated with rubber are positioned at both ends of a cylindrical roll made of Teflon, and a porous film comes into contact with the roll and the pattern rolls, such that the film may be prevented from wrinkling and a surface of the film may be prevented from being abraded due to friction between the film and surfaces of the rolls.
