Abstract

UN METODO MEJORADO, AUTOMATIZADO Y APARATO PARA EL MOLDEO DE LENTES DE CONTACTO QUE GENERALMENTE CONSISTE EN LOS PASOS SIGUIENTES: (1) SE FORMAN EN UN PRIMER Y UN SEGUNDO RETICULOS (10, 12) UNAS CAVIDADES DE MOLDEO ANTERIOR (20) Y POSTERIOR (18) RESPECTIVAMENTE SEGUN UNA RELACION SEPARADA LONGITUDINALMENTE; (2) SE VIERTE UN MATERIAL DE LENTE LIQUIDO, CURABLE (EJ., MONOMERO) EN CADA CAVIDAD ANTERIOR DEL PRIMER RETICULO; (3) SE ALINEAN Y PONEN EN CONTACTO ENTRE SI DE FORMA CENTRADA, COINCIDENTE Y SECUENCIAL LAS CAVIDADES ANTERIOR Y POSTERIOR; (4) SE CURA AL MATERIAL DE LENTES CAPTURADO ENTRE LOS MOLDES ANTERIOR Y POSTERIOR RESPECTIVOS; Y (5) SE SEPARAN LOS RETICULOS PARA LIBERAR LAS LENTES (34) MOLDEADAS ENTRE ELLOS. EN UNA RELIZACION PREFERENTE DE LA INVENCION, LAS CAVIDADES DE MOLDEO SE FORMAN POR VACIO EN LOS RETICULOS RESPECTIVOS, Y SE FORMAN UNOS RECEPTACULOS PARA GUARDARLAS (40) EN UNO O EN LOS DOS RETICULOS UTILIZADOS PARA MOLDEAR LAS LENTES.
