ABSTRACT:
To provide a slitting method of a battery separator-use resin film object that is less susceptible to occurrences of holes and tearing at the time of a slitting process. A slitting device, which is provided with a feeding roll 51 for feeding a film that is wound up to a role with its rotational velocity being controlled, a razor blade for slitting the film to a predetermined width, a sensor for detecting a tension of the film and winding rolls for winding the film up while controlling its tension, is used for carrying out a slitting process in a manner so as to satisfy the following conditions (1) and (2): (Condition 1) 5×9.8×104≦T/L≦5×9.8×105(Condition 2) 1≦R/T≦5 where L is a thickness (m) of the film object, R is a rotational velocity (m/min) of the feeding roll and T is a tension (N/m) of the film object after having been subjected to the slitting operation.
