    • A method of making a thermoplastic laminate includes the steps of extruding a tubular polymeric film; collapsing the extruded film to form a layflat film; slitting the edges of the collapsed film to form two plies; taking up both plies of the slit film onto a single take up roll to form a double wound film with two plies, the film having first and second outside surfaces; corona treating the first outside surface of the double wound film; applying a varnish to the treated surface; printing the varnished surface; corona treating the second outside surface of the double wound film; and taking up the printed film onto a wind-up roll such that the treated printed surface of one ply of the film in the roll bonds to the treated second outside surface on an adjacent wind in the roll, thereby forming a laminate. Alternatively, two separate films may be taken up on a take up roll to form a double wound film, and processed as described. The result is a trap printed laminate with good machinability and other properties.
    • 制造热塑性层压体的方法包括挤出管状聚合物膜的步骤; 塌缩挤出的薄膜以形成薄膜; 切开塌缩膜的边缘以形成两层; 将两片薄膜卷绕在单个卷绕辊上以形成具有两层的双卷绕膜,该膜具有第一和第二外表面; 电晕处理双卷绕膜的第一外表面; 在清洗表面涂上清漆; 印刷清漆表面; 电晕处理双卷绕膜的第二外表面; 并将印刷的薄膜卷绕到卷绕辊上,使得辊中的一层的经处理的印刷表面在辊中的相邻风上与经处理的第二外表面结合,从而形成层压体。 或者,两个单独的膜可以卷绕在卷绕辊上以形成双卷绕膜,并如所述进行处理。 结果是具有良好机械加工性和其他性能的疏水印刷层压板。

    • An electro-optic display cell and method of making the same is disclosed herein. The display cell has an arrangement of display electrodes in contact with a liquid within a sealed enclosure. The enclosure comprises an impervious transparent cover and a rigid structural wall member. A seal between the cover and wall member and an elastomeric plug extending between the exterior and interior complete the enclosure. The cell is filled by injecting the liquid into the presealed enclosure by perforating the plug with hollow needles also employed to remove entrapped gas. Upon withdrawal of the needles the perforations collapse to self-seal the enclosure but for added integrity the plug is also mechanically clamped. The seal and plug can be formed as an integral elastomeric moulding around a frame member forming the side wall of the enclosure and the frame member clamped between the cover and a separate base.
    • 本文公开了电光显示单元及其制造方法。 显示单元具有与密封外壳内的液体接触的显示电极的布置。 外壳包括不透水透明盖和刚性结构壁构件。 盖和壁构件之间的密封件和在外部和内部之间延伸的弹性塞子完成外壳。 通过用也用于除去截留的气体的中空针孔将塞子穿孔而将液体注入到预密封的外壳中来填充电池。 在取出针时,穿孔折叠以自封闭外壳,但是为了增加完整性,塞子也被机械夹紧。 密封件和塞子可以形成为围绕形成外壳的侧壁的框架构件的整体的弹性模制件,并且框架构件夹在盖子和单独的底座之间。
