Abstract
"PROCESSO, JUNTA ANULAR E DISPOSITIVO PARA A OBTENçãO DE UMA LENTE óPTICA A PARTIR DE UM MATERIAL POLIMERIZáVEL". O processo compreende a utilização de um molde constituído de dois casquilhos (2, 3) e de uma junta anular (4), sendo que a referida junta compreende um orifício (19) de enchimento da cavidade de moldagem com material polimerizável, sendo que a introdução deste material é efetuada após uma etapa de aplicação de um esforço mecanizado de aproximação dos casquilhos (2, 3) e antes de uma etapa de relaxamento deste esforço. Na junta (4), o orifício de enchimento (19) compreende duas seções, das quais uma primeira estende-se desde a cavidade de moldagem até à segunda seção, que é mais larga. O dispositivo compreende os meios (34-40) de aplicação de um esforço externo de aproximação dos casquilhos (2, 3) e também meios de introdução do material polimerizável na cavidade de moldagem.
