摘要： PROBLEM TO BE SOLVED: To suppress the tension and wrinkles of a film, the curling of the side end parts of the film and the like caused in the transfer part of a solution film forming process.
SOLUTION: Roller pairs R1-Rn equipped with suction members S1-Sn are arranged to the transfer part 33 to feed the film 31. The roller pairs R1-Rn are arranged on the anti-peeling surface side from a band 27 of the film 31. In the roller pairs R1-Rn, air is sucked from the gaps between upstream rollers R1a-Rna and downstream rollers R1b-Rnb and the film 31 is drawn to the roller pairs R1-Rn by the sucked air to come into contact with them. The obtained film 31 has no tension, wrinkles, curling and the like and can be continuously formed at a high speed. Further, a polarizing sheet and a liquid crystal display device excellent in optical characteristics can be obtained using a cellulose triacetate film obtained by this method.

摘要： PROBLEM TO BE SOLVED: To prevent the failure of a product by controlling the fouling of a stripping roller and a conveying roller in a method for producing a film from a solution.
SOLUTION: The film is produced from the solution by controlling the surface roughness of at least one of a stripping roller 15 and a conveying roller 20 contacting a polymer film of at least 20 wt.% solvent content on a wet basis. The surface is roughened by making its arithmetic average roughness Ra 1-5 μm or by forming 3-8 channels having a width of 1.5-7.0 μm and a depth greater than the width per 0.1 mm to make a smoothness rate 70-90%. The surface hardness of the rollers is made at least 150 Hv, and one of them is used sometimes in a film making process. As a result, the failure of the product can be prevented by controlling the fouling of the rollers 15 and 20. A cellulose acylate film produced by the method is applicable to a polarizer and a liquid crystal display.

摘要： PROBLEM TO BE SOLVED: To prevent generation of folded edge and wrinkles due to selvage curls of film in a solution film forming method.
SOLUTION: The solution film forming of a polymer is performed in the equipment having a tenter. The diameter of a first conveying roller 17 in the rear of the tenter is reduced so that the end parts of the both sides may not come into contact with the selvage curls a of the film 11. The diameter of the end parts of the both sides of the succeeding second conveying roller may be reduced in the same way. The difference between the uniform outside diameter D1 of the central part of the first conveying roller 17 and the outside diameter D2 of the both sides end part, that is, the value of two times of the step is set to be not less than 0.4 mm and not more than 6.0 mm, and the corner of the step 17a is curved or chamfered. The step can be a tapered shape instead of the stepped shape. In the case having selvage cutting process, at least one of the stepped shapes is used as the precedent conveying roller. The folded edge or wrinkles due to the selvage curls 11a is prevented to obtain the good product.

摘要： PROBLEM TO BE SOLVED: To provide a method of cutting a film capable of increasing the film productivity by improving the cutting condition of a cut part of the film without generating deficiencies such as deterioration of flatness of the cut part.
SOLUTION: In cutting a film 12, the residual volatile part of the film 12 is 1-15%, and the temperature of the cut part of the film 12 is 60°C-TG (temperature of transition of polymer to glass). Therefore, the cut end surface in excellent cutting condition can be obtained, so that cutting waste is reduced, and moreover, as the temperature is less than the TG temperature, the flatness of the cut part can be secured. Accordingly, the film can be cut stably and in excellent cutting condition.

摘要： PROBLEM TO BE SOLVED: To obtain a polarizing plate protective film in which curving becoming problematic when manufacturing a polarizing plate by sticking films of different rigidity on both surfaces of a polarizing film is suppressed. SOLUTION: The polarizing plate 50 is made by sticking the polarizing plate protective film 51, a polarizing film 52, and a polarizing plate protective film of larger rigidity together. The curvature of the polarizing plate due to difference in rigidity and that of the polarizing plate protective film 51 offset each other by using the film 51 with a predetermined curvature as the polarizing plate protective film 51, and sticking it to the polarizing film 62 with the concave surface of the curvature of the film 51 faced to the polarizing film, and thus a polarizing plate 50 can be obtained of which the curving does not become problematic.

摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of the edge curling or slackening of the side end part of a polymer film after separated from a tenter, in a manufacturing method of the polymer film.
SOLUTION: Suction nozzles 20 are arranged at the positions opposed to the side edge parts 11a on both sides of the polymer film 11 between a holding release position P where the film 11 is separated from the clips 13 of the tenter 12 and a first roller 17 with which the film 11 comes into contact first. Since the side edge parts 11a issued from the holding release position P are sucked by the suction nozzles 20 to be stretched, the occurrence of edge folding or wrinkles is prevented by the first roller 17. The suction nozzles 20 are not in contact with the side edge parts 11a and the gap with each of the side edge parts 11a is set to 10 mm or below.
