摘要： In a tenter dryer, while a film is dried, the stretch or the relaxation of the film are made. The tenter dryer includes first-third drying chambers for independently controlling the drying conditions and a shiftable stretch/relaxation device for making the stretch and the relaxation of the film with holding the film. When the stretch/relaxation device holds four edges, cutter blades provided in a drying nozzle cut the film to sheet films. Then while holding the film, the stretch/relaxation device moves between the first-third drying chambers in which drying conditions are previously controlled.

摘要： 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.
摘要翻译：将涂料浇铸到移动的流延鼓上以形成流延膜。冷却固化后，将流延膜从流延滚筒中以湿膜剥离。流延膜中的溶剂在从流延鼓剥离时的残留量用W表示。在第一拉幅机中，在干燥的同时，将湿膜沿其宽度方向拉伸以形成中间膜。在湿膜中的残留溶剂量达到（W-100）重量％之前，湿膜在其宽度方向上变宽，使得增加的宽度不小于前面的宽度的105％且不大于130％宽度增加。中间膜在第二拉幅机中在其宽度方向上被拉伸和加宽，使得增加的宽度不小于宽度增加之前的宽度的110％且不大于160％。因此，与常规膜相比，可以制备具有Re高的光学特性的膜，并且Rth / Re的值降低。

摘要： A TAC film has a thickness profile in which its thickness decreases from side edge portions toward a center portion. The TAC film has a retardation profile in which its in-plane retardation Re decreases from the side edge portions toward the center portion. The retardation profile is caused by the thickness profile. In a tenter section, the TAC film is stretched in a width direction while the side edge portions are being held. A difference of increase in the in-plane retardation Re of the film in the width direction after the stretching is compensated by a difference of the in-plane retardation Re of the film in the width direction before the stretching.
摘要翻译： TAC膜具有厚度分布，其厚度从侧边缘部朝向中心部分减小。 TAC膜具有其面内相位差Re从侧边缘部分向中心部分减小的相位差分布。延迟分布由厚度分布引起。在拉幅机部分中，TAC膜在保持侧边缘部分的同时沿宽度方向拉伸。通过拉伸前的宽度方向上的膜的面内相位差Re的差异来补偿拉伸后的宽度方向上的膜的面内延迟Re的增加差。

摘要： A casting film is made by casting dope including polymer and solvent on a casting drum whose surface is cooled. The casting film becomes to have a self-supporting property by cooling solidification, and then peeled as a wet film from the casting drum. The wet film is fed into a pin tenter in which both side edges of the wet film is held by plural pins. The wet film is dried while conveyed through the pin tenter, to become a film. Next, the film having predetermined X-ray diffraction intensity is fed into a clip tenter. While the film whose both side edges are held by clips is conveyed, it is stretched in the width direction thereof at a stretch rate in a range of 15% to 40%, to control molecular orientation in the film.

摘要： Side edge portions of a film in which a content of a remaining solvent is at least 30 wt. % are contacted to side parts of first-third rollers with suctioning through suction ducts. Thus a middle portion between the side edge portions is not contacted to the rollers, and the film is transported toward a tenter device in accordance with the rotation of the rollers. In the rollers, each side part of the rollers has a larger diameter of a middle part. At least one of intervals between the neighboring rollers is from 1 mm to 200 mm, and the lapping angle is from 1° to 180°. Toward the middle part of the film, and air is fed in a roller side. The obtained film doesn't have any neither crumples, wrinkle, curl and the like, and foreign materials are hardly adhered. Therefore the continuous film production can be made stably.

摘要： A dope is cast onto a drum. A casting film is cooled and solidified by the drum. The casting film is peeled as a film containing a solvent. The peeled film is guided to a tenter. In the tenter, in a first drying step, the film is dried by dry air from an air duct while being stretched in the width direction in a state that side edge portions of the film are held by pins. Thereafter, in a second drying step, the film is dried while tension is applied to the film in the width direction. A first ratio calculated by (a moving speed of the pins)/(a rotation speed of the drum), a second ratio calculated by L2/L1, and a third ratio calculated by L3/L2 satisfy 0.94≦(the first ratio)/{(the second ratio)·(the third ratio)}≦0.97.

摘要： Cellulose triacetate film is produced by a solution casting process. Dope, which includes cellulose triacetate and mixed solvent with methyl acetate, is cast on a rotary drum in a form of bead by use of a flow casting die, to form gel film. When a self-supporting characteristic of the gel film becomes higher than one limit value, the gel film is stripped from the rotary drum by use of a stripping roller, to obtain the cellulose triacetate film. During the casting step, a surface of the rotary drum is cooled at −10° C. or lower.

摘要： A clip to hold the film has a clip body, a flapper, a press slider and a rail mount. A pair of the press sliders is located in both sides of the flapper. A coil spring presses the press slider upward. A pair of entrance side film release members, provided in the tenter entrance, presses the press slider downward to press the lateral edge portions of the film by the press sliders. At the film hold position, the flapper rotates from a release position to a hold position to hold the film, and the flapper is kept at the hold position by a torsion spring. The flapper holds the film 26 after the press slider holds the lateral edge portions of the film, so the flapper can hold the film even when the lateral edge portions of the film are curled.
