    摘要: PURPOSE: A rolled porous film, and a method and an apparatus for fabricating the same are provided to reduce the manufacturing cost of the rolled porous film by locally expanding a film combined with a non-woven fabric through a rolling roll. CONSTITUTION: Resin having inorganic material is extracted from an extractor in a thickness below 20g/m2 in order to fabricate a porous film. In a state that the extracted film is molten, a non-woven fabric with an amount below 20g/m2 is applied to one side of the extracted film. Then, the film combined with the non-woven fabric passes through a rolling roll including a local expanding roll(1) and an elastic rubber roll(2) in such a manner that fine pores are distributed in the film about a local expanding mark. Then, the local expanding mark is distributed over the whole area of the film.
