WIPO Patent Application WO/2013/136725
Kind Code:
A1
Abstract:
One aspect of the present invention is a production method for a stretched long film involving a diagonal stretch process in which a long film is diagonally stretched at an angle of greater than 0° and less than 90° with respect to the transverse direction, wherein a heating device that heats the long film by blowing hot air at the long film is used as the diagonal stretch device in the diagonal stretch process, a device capable of changing the running position of the long film is used to diagonally stretch the long film at a certain angle of greater than 0° and less than 90° with respect to the transverse direction, and the position where the hot air is sprayed is adjusted so as to accommodate the running position of the long film during the diagonal stretch process.
