Production method of film laminates and production apparatus used therein

Abstract

The manufacturing process relates to a manufacturing of a film laminate in which at least one side of the film 1 is provided with another film 2. The process comprises the steps of arranging the film 2 on at least one side of the film 1, feeding an adhesive liquid to the laminating part of the film 1 and film 2, at the same time feeding a liquid countering the adhesive liquid flowing toward at least one end of the film 1 from at least one end of the film 1 and laminating the film 1 and film 2 by pressing them. To provide a manufacturing process of film laminates by which the leakage of an adhesive liquid from the edge of the laminates in laminating one film to the other is prevented without solidifying the adhesive, a manufacturing apparatus used for the manufacturing process, a film laminate obtained by the manufacturing process and an optical film and an image display device provided with the film.

Description

technical field

[0001] The present invention relates to a method for producing a film laminate in which other films are provided on at least one side of the film by means of an adhesive, a production device used in the method, a film laminate obtained by the production method, a film laminate obtained by the method A polarizing plate obtained by the production method, an optical film including the polarizing plate, and an image display device. Background technique

[0002] In the past, in the method of laminating films with an adhesive liquid called an adhesive or an adhesive, there was usually a method of laminating after coating the adhesive liquid on the film, or supplying the adhesive liquid to a pair of films A method of bonding between a pair of rollers and the like through a press-bonding mechanism (for example, refer to Patent Document 1). In such lamination, when using a low-viscosity adhesive, there is a problem of contamination of the film and the device due to o...
