    • A device for mounting a roll of material that includes a fiber core around which the material is placed. The device includes a lightweight, polymeric collett that is inserted into the fiber core. The polymeric collett has a plurality of individual segments that expand radially with respect to a central axis of the roll of material. Each of the plurality of individual segments includes an inner wall and an outer wall. The inner walls of the plurality of individual segments define a cavity. The outer walls engage an interior surface of the fiber core. An arbor engages the inner walls of the plurality of individual segments and forces them outwardly to place the outer walls into tight, frictional engagement with the interior surface of the fiber core.
    • 一种用于安装材料卷的装置,其包括纤维芯,材料放置在所述纤维芯周围。 该装置包括插入到纤维芯中的轻质聚合物。 聚合物混合物具有多个相对于材料卷的中心轴线径向膨胀的单个部分。 多个单个段中的每一个包括内壁和外壁。 多个单个段的内壁限定了空腔。 外壁接合纤维芯的内表面。 一个心轴与多个单独节段的内壁接合并迫使它们向外,以使外壁与纤维芯的内表面紧密摩擦接合。

    • An improved vacuum exposure frame for use in making exposed aluminum printing or lithographic plates permits the use of unworked glass, preferably tempered glass, rather than polycarbonate plexiglass (which is easily scratched) of the prior art replacement of the transparent image-exposure-window material. The frame is routed on the lower aperture-facing portion of the exposure window, preferably by a 90.degree. routing having a horizontal face and a vertical face surrounding and defining the aperture underside. A preferred embodiment has a reverse depression preferably routed out of the horizontal face and a sealant-adhesive is inserted into the reverse depression and along the vertical face so as to secure the unworked glass to the frame. Separate ID windows with long lasting polycarbonate inserts are also in the frame where the main image exposure window aperture is shaped to contain preferably only the book pages to be exposed onto the aluminum plate. Additionally, glued polycarbonate vacuum towers of the prior art are replaced by aluminum vacuum towers threadably mechanically secured to the frame and not involved with the windows and their usage.
    • 用于制造暴露的铝印刷或平版印刷板的改进的真空曝光框允许使用未加工的玻璃,优选钢化玻璃,而不是使用现有技术的透明图像曝光窗材料的聚碳酸酯有机玻璃(其容易被划伤) 。 框架被布置在曝光窗口的较低孔径部分上,优选地通过90°布线具有水平面和围绕并限定孔径下侧的垂直面。 优选的实施例具有优选地从水平面引出的反向凹陷,并且将密封胶粘合剂插入到反向凹陷中并且沿着垂直面,以将未加工的玻璃固定到框架上。 具有长持久聚碳酸酯插入物的独立的ID窗口也在主要图像曝光窗口孔被成形为优选仅包含要暴露于铝板上的书页的框架中。 此外,现有技术的胶合聚碳酸酯真空塔由可螺纹地机械地固定到框架上的铝真空塔代替,并且不涉及窗户及其使用。
