Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA REPLEGAR HACIA DENTRO LA MEMBRANA EN UN FILTRO DE EXTRACCION PARA SUSPENSIONES. EN EL PROCEDIMIENTO, AL CERRAR EL FILTRO, SE PRODUCE EN EL INTERIOR DE LA MEMBRANA UNA DEPRESION FRENTE A LA PRESION AMBIENTE Y LA MEMBRANA SE DEFORMA PARA IMPEDIR, MEDIANTE INFLUENCIAS EXTERIORES, LA FORMACION DE UN PLIEGUE DE ARRUGA SENCILLO, SOBRESALIENTE LATERALMENTE DEL BORDE DE LA ENVOLVENTE EXTERIOR, HASTA QUE SE OBTIENE UN PLEGADO TRIPLE O MULTIPLE DE LA MEMBRANA, QUE YA NO SOBRESALE LATERALMENTE DEL BORDE DE LA ENVOLVENTE EXTERIOR. EL DISPOSITIVO SE CARACTERIZA PORQUE EL DISPOSITIVO DE PROTECCION TIENE LA FORMA DE UN TUBO TELESCOPICO (31, 32, 33) QUE RODEA A UN BRAZO DE OBTURACION (17).
