See full text

An apparatus imparts concaves/convexes to a sheet-like object by passing the sheet-like object between a pair of rollers facing each other. At least one of the rollers is a roller a surface of which is formed by laminating a single or a plurality of circular plates each provided with concaves/convexes at a peripheral edge thereof. An interval keeping mechanism is provided between the circular plates provided with concaves/convexes at the peripheral edges. At least one of the rollers is formed with a roller surface by laminating a single or a plurality of circular plates each having only convexes of concaves/convexes portions at a peripheral edge thereof. By the roller, convexes can be imparted to one face of front and back surfaces of a sheet-like object.
