Abstract
Preformed electroforms are sliced into elongated slab shaped bodies having spaced generally parallel respective side walls so that an edge wall thereof has defined therein cube corner retroreflective units. When a plurality of such slab shaped bodies are positioned together to provide a region of cube corner type retroreflective units, there results a mold element which can be incorporated into a mold for making reflector units of transparent solid material or the like wherein angled retroreflective units and so-called standard retroreflective units are distributable over the entire face of a product reflector unit and from which air in the mold cavity can readily escape during filling in a molding operation.
