    • A lenticular pattern forming roll (44), used for forming a lenticular screen, includes a chill roll (44a) and a lenticular sleeve (44b) positioned on the chill roll, and may be readily used in combination with an extruder (41) for extruding a plastic sheet (46). The sleeve has a lenticular pattern formed on an outer surface for forming a corresponding lenticular pattern in the plastic sheet. The sleeve may be readily manufactured and transported to a desired location to be installed on the chill roll, and may also be removed from the chill roll and transported for resurfacing and without requiring transporting of the chill roll. The lenticular sleeve may preferably comprise an amorphous nickel-phosphorous composition defining at least a radially outermost portion of the sleeve in which the lenticular pattern is formed, preferably 75 top 86 percent by weight of nickel and 14 to 35 percent by weight phosphorus, and may be formed by electrodepositing or electroless depositing. The sleeve may be slit and flattened to define a flat lenticular body for molding a lenticular screen.
    • 用于形成双凸透镜屏幕的透镜状图案成形辊(44)包括位于冷却辊上的冷却辊(44a)和双凸透镜套筒(44b),并且可以容易地与用于形成双凸透镜的挤出机(41) 挤出塑料片(46)。 套筒具有形成在外表面上的透镜状图案,用于在塑料片中形成相应的透镜状图案。 套筒可以容易地制造并运输到期望的位置以安装在冷却辊上,并且还可以从冷却辊上移除并运输用于表面重修并且不需要运输冷却辊。 微透镜套筒可以优选地包括非晶态镍 - 磷组合物,该非晶态镍 - 磷合成物至少限定其中形成微透镜图案的套筒的径向最外部分,优选75重量%的86重量%的镍和14重量%至35重量%的磷,并且可以 通过电沉积或无电沉积形成。 套筒可以被切割并且变平以限定用于模制透镜状屏幕的扁平透镜体。

    • A method and apparatus are provided for automatic and hands-free threading of an elastomeric mix into a calender set of rolls comprising one or more pairs of rolls that have a nip between them. A wedge is provided with a tip that is positioned downstream from the nip and at a predetermined distance from the nip. As the rolls of the nip are rotated, the tip of the edge removes all, or a desired portion of, the elastomeric mix from a first roll of the nip so as to transfer the elastomeric mix to a second roll of the nip. The tip of the wedge may be placed into contact with the first roll. The wedge may also have an arcuate surface, shaped e.g., like the outer surface of the first roll, and positioned a predetermined distance from the outer surface of the first roll.
    • 提供了一种方法和装置,用于将弹性体混合物自动和免手动穿入砑光辊组中,所述辊组包括一对或多对辊,它们之间具有辊隙。 楔形件设置有位于辊隙下游并且距辊隙预定距离的尖端。 当辊隙的辊旋转时,边缘的尖端从辊隙的第一辊去除弹性体混合物的全部或期望的部分,以便将弹性体混合物转移到辊隙的第二辊。 楔形物的尖端可以放置成与第一辊接触。 楔形物还可以具有弧形表面,其形状例如与第一辊的外表面成形,并且与第一辊的外表面定位成预定距离。
