Abstract

"PROCESSO DE FABRICAçãO DE UMA PLURALIDADE DE LâMINAS PARA USO EM UM MOLDE ADEQUADO PARA USO NA FORMAçãO DE ARTIGOS RETRO-REFLETORES DE ARESTAS CúBICAS, MOLDE, E, ARTIGO RETRO-REFLETOR". Um processo é apresentado para fabricar uma pluralidade de lâminas para uso em um molde adequado para uso na formação de artigos retro-refletores de arestas cúbicas. Cada lâmina tem em oposição as primeiras e segunda superfícies principais definindo entre elas um primeiro plano de referência. Cada lâmina ainda inclui uma superfície de trabalho conectando as primeira e segunda superfícies principais. A superfície de trabalho define um segundo plano de referência substancialmente paralelo à superfície de trabalho e perpendicular ao primeiro plano de referência, e um terceiro plano de referência perpendicular ao primeiro plano de referência e ao segundo plano de referência. O processo inclui orientar uma pluralidade de lâminas para terem seus respectivos primeiros planos de referência paralelos um em relação ao outro e dispostos em um primeiro ângulo relativo a um eixo de referência fixo. Pelo menos dois conjuntos de ranhuras são formados na superfície de trabalho. Cada conjunto de ranhuras inclui pelo menos duas ranhuras conformadas em V adjacentes paralelas na superfície de trabalho das lâminas. Os pelo menos dois conjuntos de ranhuras formam as primeira, segunda e terceira superfícies de ranhuras, que se intersecionam substancialmente de forma ortogonal, para formarem uma pluralidade de elementos de arestas cúbicas. Cada elemento da pluralidade de elementos de arestas cúbicas é preferivelmente localizado essencialmente em uma lâmina da pluralidade de lâminas. A pluralidade de lâminas pode ser orientada em um segundo ângulo em relação ao eixo de referência fixo, antes de formar pelo menos um dos conjuntos de ranhuras. Um molde de acordo com a presente invenção a um artigo retro-refletor feito a partir dele, são também apresentados.
