Abstract:
A method of monolithically forming one piece reflective pavement or delineator marker including multiple of cube corner reflective elements comprising the steps of:a) providing tooling means which allow injection molding of said reflective pavement marker integrally including the cube corner reflective elements, said tooling means can mold said pavement marker in one stage or two stage injection molding cycle, b) providing hollow cavity means which define the interior load carrying partition walls and allow integrally forming the cube corner reflective elements within said pavement marker during said injection molding process, c) providing the angular positions of said hollow cavity means with respect to the inclined reflective face of said pavement marker allowing uninterrupted ejection cycle during said injection molding of said reflective pavement marker, whereby said reflective pavement marker will be monolithically formed including said cube corner reflective elements and the load carrying partition walls.
