The film-holding unit has a plurality of upper holding rollers placed in parallel at intervals in the MD of the film above the transfer path of film, and a plurality of lower holding rollers placed opposite to upper holding rollers below the transfer path of film such that the plurality of lower holding rollers work together with the plurality of upper holding rollers to sandwich the film vertically between the rollers. Upper holding rollers and lower holding rollers are rotatably supported such that their rotational axes are inclined outward in the TD of film toward a downstream side of the MD of film. | 02-14-2013 |
| 20150035199 | METHOD FOR PRODUCING AROMATIC POLYIMIDE FILM WHEREIN LINEAR EXPANSION COEFFICIENT IN TRANSVERSE DIRECTION IS LOWER THAN LINEAR EXPANSION COEFFICIENT IN MACHINE DIRECTION - An aromatic polyimide film having a TD linear expansion coefficient lower than that MD linear expansion coefficient is produced by an industrially advantageous process which is performed under such conditions that a self-supporting aromatic polyimide precursor film having a solvent content 25-45 wt % and an imidation ratio 5-40% is prepared and stretched in the transverse direction under heating initially at 80-240° C. and the stretched self-supporting aromatic polyimide precursor film is subsequently converted to a self-supporting aromatic polyimide film by heating the precursor film at 350-580° C. | 02-05-2015 |
| 20150352752 | AN AQUEOUS -SOLVENT BASED PROCESS FOR CONTINUOUS MANUFACTURING OF SUPPORTED ION SELECTIVE MEMBRANES - A membrane, for example an ion exchange membrane, is made by preparing a curable liquid using at least one aqueous solvent. The curable liquid is continuously cast onto a substrate to form a membrane precursor. The membrane precursor is continuously cured to form a membrane. Optionally, the curable liquid may be made by mixing a water soluble aliphatic sulfonic acid monomer with a pair of crosslinking monomers and a water soluble free-radical generating catalyst. Optionally, the method may include one or more steps of processing the membrane. | 12-10-2015 |

| 20090085246 | METHOD FOR PRODUCING FILM - Dope is cast onto a moving casting drum to form a casting film. After being cooled to be solidified, the casting film is peeled as a wet film from the casting drum. A residual amount of solvent in the casting film at the time of peeling it from the casting drum is denoted by W. In a first tenter, while being dried, the wet film is stretched in its width direction to form an intermediate film. Before the residual amount of solvent in the wet film reaches (W-100) wt %, the wet film is widened in its width direction such that the increased width is not less than 105% and not more than 130% of the width before the width increasing. The intermediate film is stretched and widened in its width direction in the second tenter such that the increased width is not less than 110% and not more than 160% of the width before the width increasing. Thus, it is possible to produce a film having optical properties in which Re is high and a value of Rth/Re is decreased in comparison with conventional films. | 04-02-2009 |
| 20090108489 | FILM STRETCHING AND RELAXING METHOD AND SOLUTION CASTING METHOD - In a stretching area of a tenter, a film is stretched in a Z2 direction. The film has a residual solvent level of not less than 0.03 wt. % and not greater than 10 wt. %. Out of the stretching area, the film enters a relaxing area to relax the film at a predetermined relaxation rate Y (%). Surface temperatures Tp, Ts, Th (° C.) and the relaxation rate Y are controlled to satisfy an expression of 6≦{(− 1/12)×Tp}+{(−⅕)×Ts}+{(⅓)×Th}+Y≦18, where Tp is the temperature of the film five seconds before entering the stretching area, Ts is the temperature of the film at the center in a film transfer direction of the stretching area, and Th is the temperature of the film five seconds after departing the stretching area. | 04-30-2009 |

| 20130234360 | METHOD AND APPARATUS FOR PRODUCING CELLULOSE ACYLATE FILM - Fatty acid is dissolved in a second solvent to prepare a fatty acid solution. The fatty acid solution is added to a dope prepared by dissolving cellulose acylate and a plasticizer in a first solvent. Thereby, a casting dope containing the fatty acid is prepared. The mass of the fatty acid to be added to the dope is in the range of 1×10 | 09-12-2013 |
