A manufacturing apparatus is provided for manufacturing antubular resin film of high quality and little thickness variations, whichnis stretched and given an orientation, and suitable as retardation film ornthe like. It comprises a stretching section (6) for stretching the tubularnresin film (20), and a maintaining section (7) for maintaining a shape ofnsaid tubular resin film (20) stretched. Further, said stretching sectionn(6) is arranged to apply a stretching force to said tubular resin film fornlongitudinally and/or circumferentially stretching said tubular resinnfilm (20). |
