| titleOfInvention | Method for manufacturing polarizing film and apparatus for manufacturing polarizing film |
| abstract | [Problem] To provide the manufacturing method and manufacturing apparatus of the polarizing film which can manufacture the polarizing film with uniform shrinkage force in the width direction. [Solution Means] As a manufacturing method of a polarizing film, the extending|stretching treatment process of performing an extending|stretching process between a pair of nip rolls is included, conveying a polyvinyl alcohol-type resin film, An extending|stretching treatment process WHEREIN: Film conveyance among a pair of nip rolls In the direction, the width of the upstream nip roll is A [mm], the width of the downstream nip roll is B [mm] in the film conveyance direction, and the polyvinyl alcohol-type resin film just before contacting the downstream nip roll in the said film conveying direction. The manufacturing method of a polarizing film which satisfy|fills 3.0≤Y<7.0 [in formula, set it as Y=(A+B+C)/C] when making the width|variety of C [mm]. |
