    • A casting dope (11) prepared from CAP, additive and solvent is cast onto a casting belt (35), peeled and dried to be a primary film (14), and wound to a primary film roll (16). After the storage, the primary film (14) is unwound and fed into a tenter device (18). In the tenter device (18), while the stretch in the widthwise direction is performed, a relaxation of the primary film (14) in the longitudinal direction is made. If an extent percentage of the stretch is less than 70% to the predetermined value, the relation is started. The primary film (14) is fed out as a produced polymer film (22) from the tenter device (18), and the polymer film (22) is wound up to a product film roll (24). On the produced polymer film (22), the in-plane retardation increases and the thickness retardation decreases. Thus the optical properties become preferable.
    • 将由CAP,添加剂和溶剂制备的浇铸液(11)浇铸到铸造带(35)上,剥离并干燥成初级膜(14),并缠绕到初级膜卷(16)上。 储存后,将初级薄膜(14)退绕并进入拉幅机装置(18)。 在拉幅装置(18)中,在进行宽度方向的拉伸的同时,使主膜(14)沿长度方向松弛。 如果拉伸的程度百分比小于预定值的70%,则开始关系。 从拉幅装置(18)将初级薄膜(14)作为生产的聚合物薄膜(22)送出,将聚合物薄膜(22)卷绕到产品薄膜卷(24)上。 在所生产的聚合物膜(22)上,面内延迟增加,厚度延迟减小。 因此,优选光学性质。

    • A web separating device includes a cutting/joining drum, which is rotatable in contact with web of optical film on a peripheral surface thereof. A cutting drum is positioned for contacting the cutting/joining drum peripherally, and has a cutter for cutting the web being supplied in a width direction in cooperation with the cutting/joining drum, to obtain upstream and downstream web sections. A joining drum is positioned for contacting the cutting/joining drum peripherally, and attaches a guide leader to a front end of the upstream web section. Guide rollers are disposed for allowing passage of the web and the upstream and downstream web sections in a non-contact manner before and after being cut or attached.
    • 纸幅分离装置包括切割/接合滚筒,该切割/接合滚筒在其外周表面上可转动地与光学薄膜的幅材接触。 切割滚筒定位成使周边的切割/接合滚筒接触,并且具有用于切割与切割/接合滚筒协同地在宽度方向上供应的卷材的切割器,以获得上游和下游卷筒纸部分。 定位接合滚筒以使周边的切割/接合滚筒接触,并将引导引导件附接到上游卷筒纸部分的前端。 引导辊设置成允许在切割或附接之前和之后以不接触的方式使幅材和上游和下游幅材部分通过。

    • A film deposition method deposits a film on a surface of a substrate in strip form traveling on a peripheral surface of a cylindrical drum in at least one film deposition compartment around the peripheral surface of the drum. The method disposes previously a differential compartment between one film deposition compartment and a compartment including a wrapping space containing at least one of a first position at which the substrate starts to travel on the drum and a second position at which the substrate separates from the drum, the differential compartments communicating with the compartment including the wrapping space and the film deposition compartment, sets a first pressure of the wrapping space lower than a second pressure of the at least one film deposition compartment and performs film deposition in the film deposition compartment with electric power supplied to the drum.

    • A casting dope (27) prepared from CAP, additive and solvent is cast onto a belt (46) and peeled as a wet film (74) that is drawn in the longitudinal direction in a transporting area (80). In a tenter device (47), while the wet film (74) is stretched in the widthwise direction, a relaxation of the wet film (74) in the longitudinal direction is made. If an extent percentage of the stretch is less than 70%, the relation is started. The wet film (74) is fed out as a polymer film (82) from the tenter device (47). On the polymer film (82), the in-plane retardation increases and the thickness retardation decreases. Thus the optical properties become preferable.
