Abstract This method for manufacturing a long stretched film has a long film formation step, an oblique stretching step, and a winding step, an oblique stretching device has a heating furnace and a gripper travel support tool, and the stretching direction of the oblique stretching device can be arbitrarily changed, the gripper travel support tool is provided with a drive shaft, and in the oblique stretching step, a long film is continuously heated by a planar heater provided between the drive shaft and the long film in at least a stretching zone inside the heating furnace. Procédé de fabrication d'un film étiré de grande longueur présentant une étape de formation de film long, une étape d'étirement oblique, et une étape d'enroulement. Un dispositif d'étirement oblique possède un four de chauffage et un outil de support de déplacement de préhension et la direction d'étirement du dispositif d'étirement oblique peut être arbitrairement changée. L'outil de support de déplacement de préhension est pourvu d'un arbre d'entraînement et, dans l'étape d'étirement oblique, un long film est chauffé en continu par un élément chauffant plat disposé entre l'arbre d'entraînement et le long film dans au moins une zone d'étirement à l'intérieur du four de chauffage.
