Abstract

PURPOSE:To obtain a roll having the satisfactory winding property by cutting an orientated film by a laser beam and afterward, carrying out pressing processing on a cutting part. CONSTITUTION:After the orientated film 1 is continuously conveyed, lug parts 4 on both sides in the width direction of the film 1 are continuously cut and eliminated by a take-up machine 2 and the film 1 is rewound thereby as a film roll 3. The lug parts are cut by the irradiation of the laser beam 5. The laser beam 5 is projected at almost right angles to the rear of the orientated film 1 from an irradiating device 6. A pressing nip roll 11 is provided immediately after a cutting point of the laser beam and the distance between the cutting point and the pressing nip roll 11 is set before the fused and cut film edge is cooled end solidified by heat radiation. By this method, the satisfactory film winding quality without a lug rise is obtained.
