ABSTRACT:
Slab shaped bodies are individually prepared by machining and then are assembled into mold portions which portions are adapted for incorporation into a mold for forming cube-corner type retroreflective surfaces in a body formed by such a mold. Two such slab shaped bodies in side by side relationship cooperate to provide a plurality of individual cube corner type retroreflective units extending along adjoining top side edge wall portions of such bodies. A plurality of such slab-shaped body pairs are employable to provide a region of cube corner type retroreflective units. Such slab shaped bodies make possible a variety of new and useful retroreflectors.
