A method is disclosed for manufacturing a plurality of laminae for use in a mold suitable for use in forming retroreflective cube corner articles. Each lamina has opposing first and second major surfaces defining therebetween a first reference plane. Each lamina further includes a working surface connecting the first and second major surfaces. The working surface defines a second reference plane substantially parallel to the working surface and perpendicular to the first reference plane and a third reference plane perpendicular to the first reference plane. The method includes (a) orienting a plurality of laminae to have their respective first reference planes parallel to each other and disposed at a first angle relative to a fixed reference axis, (b) forming a plurality of cube corner elements on the working surfaces of the plurality of the laminae, wherein the plurality of cube corner elements have three approximately mutually perpendicular lateral faces that mutually intersect to define a cube corner element peak, and (c) removing a plurality of laminae from the assembly to alter the configuration of the mold surface.
(ZH) 一种用来制造多个使用在模具中的薄片(10a、b、c、d、e、f、g、h)的方法，所述模具适用于形成反光立体角制品。每一薄片具有对置的第一和第二主表面，所述两表面之间形成一第一参考平面。每一薄片还包括一将第一和第二主表面连接起来的工作面。所述工作面形成一基本平行于所述工作面并垂直于所述第一参考平面的第二参考平面以及一垂直于所述第一参考平面的第三参考平面。所述方法包括以下步骤：(a)对一组件内的多个薄片进行取向，以使它们各自的第一参考平面彼此相互平行，并设置得与一固定参考轴线呈一第一角度；(b)在所述多个薄片的工作面上形成多个立体角单元，其中，所述多个立体角单元具有三个大体相互垂直的侧面，这些侧面彼此相交而形成一立体角单元顶峰；以及(c)从所述组件中除去多个薄片(10c，f)，以改变所述模具表面的构造。
