Abstract

"LâMINA, PROCESSO PARA PRODUçãO DA MESMA, PLURALIDADE DE LâMINAS, MOLDE, E, INSTALAçãO DE MOLDE". São descritos lâminas (12) adequadas para o uso em um molde adequado para o uso em formação de laminado retro-reflexivo e processos para a produção de tais lâminas. Uma lâmina representativa (12) inclui uma fileira simples de elementos de ângulo cúbico opticamente opostos, dispostos em sua superfície de trabalho. A superfície de trabalho de uma lâmina é provida com uma pluralidade de elementos de ângulo cúbico formados pelas superfícies ópticas, definidas por três conjuntos de fendas. Superfícies correspondentes de conjuntos de fendas opostas intersectam substancialmente ortogonalmente ao longo de uma borda de referência, para definir primeiras e segundas superfícies ópticas (60, 70) dos respectivos elementos de ângulo cúbico. A terceira superfície óptica de cada elemento de ângulo cúbico respectivo é definida por uma superfície do terceiro conjunto de fendas (46).
