    • The apparatus is for forming a resin film from a resin for a middle portion to form a resin film main body of the resin film and a resin for edge portions to form both side edge portions in a crosswise direction of the resin film. The apparatus comprises: a feed block which includes a joining part where the resin for the middle portion in a molten state and the resin for the edge portions in a molten state are joined in such a manner as to enclose both side edges in the crosswise direction of the resin film main body with the resin for the edge portions; and an extruding die through which the joined resins are extruded to form the resin film. Thus, a method and apparatus for forming the resin film can avoid the inclusion of the resin for the middle portion in the trimmed-off selvages while preventing the film separation of the resins for the middle portion and for the edge portions, and therefore, increase the recyclability and the productivity of the resin film. This is a divisional of application Ser. No. 10/725,053 filed Dec. 2, 2003. The entire disclosure of the prior application, application Ser. No. 10/725,053 is hereby incorporated by reference.
    • 该装置用于从用于中间部分的树脂形成树脂膜以形成树脂膜的树脂膜主体和用于边缘部分的树脂,以在树脂膜的横向方向上形成两个侧边缘部分。 该装置包括:进料块,其包括接合部分,其中熔融状态的中间部分的树脂和熔融状态的边缘部分的树脂以沿横向包围两个侧边缘的方式接合 树脂膜主体与边缘部分的树脂; 以及将挤出连接的树脂形成树脂膜的挤出模具。 因此,用于形成树脂膜的方法和装置可以避免在修剪边缘中包含用于中间部分的树脂,同时防止用于中间部分和边缘部分的树脂的膜分离,因此增加 树脂膜的可回收性和生产率。 这是一个应用程序的分区。 2003年12月2日提交的第10 / 725,053号。 10 / 725,053号通过引用并入本文。

    • In the resin film forming method for extruding a fused resin from an extruder die to form a resin film, the second resin forming both ends in width direction of the resin film uses a resin greater in extension viscosity than the first resin forming the center in width direction of the resin film. Thereby, even if production conditions such as resin condition and operating conditions change, faults such as neck-in and its resultant thickening at both ends of the resin film can be suppressed. In the production of a laminate by nipping a support and a resin film of a thermoplastic resin by means of a nip roller and a cooling roller while coating the resin film onto the surface of the support, the accompanying air following the rotation of the cooling roller to the nip point is shut off by blowing a gas permeable through the resin film from a gas jet nozzle toward the surface of the cooling roller. Thereby, the occurrence of craters can be inhibited, a laminate excellent in surface appearance can be produced and the production of a laminate effective especially at the time of a line speed rise in the laminate production is performable.
    • 在从挤出机模头挤出熔融树脂以形成树脂膜的树脂膜形成方法中,在树脂膜的宽度方向两端形成的第二树脂使用的树脂的延伸粘度大于形成宽度中心的第一树脂 树脂膜的方向。 由此,即使在树脂状态,工作条件等生产条件变化的情况下,也能够抑制树脂膜的两端的颈部及其加厚等缺陷。 在通过夹持辊和冷却辊夹持支撑体和热塑性树脂的树脂膜同时将树脂膜涂覆到支撑体的表面上来生产层压体时,随着冷却辊旋转的伴随空气 通过从气体喷射喷嘴朝向冷却辊的表面吹入可透过树脂膜的气体来切断夹点。 由此,可以抑制凹坑的发生,可以制造表面外观优异的层压体,特别是在层叠体制造中的线速度上升时,可以实现层叠体的生产。
