| abstract |
Provided is a method for producing an optical film, in which a plurality of original films are successively stretched in the longitudinal direction and less likely to be broken by stretching. SOLUTION: A strip-shaped original film is fed from the leading end side to a stretching device that stretches the fed strip-shaped film in the longitudinal direction, and the trailing end side and the next original of the fed original film are fed in advance. By connecting the leading end side of the anti-film with a heat seal, it is a method for producing an optical film that is successively sent to the stretching device and stretched successively, and the trailing end side of the original film and Before feeding the connecting portion with the leading end side of the next original fabric film into the stretching device, both sides are cut into an arc shape, and the width of the connecting portion after cutting is 50 to 70% of the original fabric width. The manufacturing method of the optical film characterized by the above-mentioned. [Selection] Figure 5 |
