Abstract

EL DISPOSITIVO DE LA INVENCION SE REFIERE A LA REGULACION DE LA RANURA DE VENTILACION EN PRENSAS, PARA LA OBTENCION DE OBJETOS CERAMICOS CON MASA ROCIABLE. POR MEDIO DE LA REGULACION DE LA RANURA DE VENTILACION, BIEN DESDE EL LADO DE LA MEMBRANA O BIEN DESDE EL LADO DEL REVESTIMIENTO, DEBEN SER TENIDAS EN CUENTA LAS DIFERENTES CONDICIONES CON RESPECTO A LAS PROPIEDADES DE LA MASA Y DEL ARTICULO CERAMICO A FABRICAR. PARA LA REGULACION DE LA RANURA DE VENTILACION (40), LA PARTE DE APOYO INFERIOR (24) ESTA PROVISTA DE UN SUPLEMENTO (42) EN FORMA DE UN ANILLO ROSCADO. EN COMBINACION CON EL JUEGO DE LA ROSCA EXTERIOR, DE LA PARTE DE APOYO INFERIOR (24), LA MEMBRANA (18) ES LEVANTADA EN CASO NECESARIO, Y LA RANURA DE VENTILACION ES ESTRECHADA.
