Abstract

Dispositivo cambiador de filtro para extrusionadora de materia plástica, del tipo que comprenden dos filtros coaxiales de eje perpendicular al eje de la extrusionadora y alojados en un cuerpo de filtro intercalado entre la extrusionadora y su hilera estan do provistos los dos filtros de canalizadoras próximas de alimentación y de evacuación que permiten poner en la trayectoria de deslizamiento o de retirar la trayectoria de deslizamiento de la materia plástica a uno de los dos filtros a elección, caracterizado porque los con dos filtros están formados en un cilindro de revolución y porque las secciones de entrada de las canalizaciones próximas de alimentación y las secciones de salida de las canalizaciones próximas de evacuación tienen sus centros situados sensiblemente sobre una misma sección recta del citado cilindro de revolución, estando respectivamente colocadas las citadas secciones de entrada y de salida correspondientes a cada uno de los filtros de modo a coincidir por desplazamiento angular con la canalización del cuerpo de filtro que recibe la materia plástica procedente de la extrusionadora y con la canalización del cuerpo de filtro que asegura el transporte de la materia plástica hacia la hilera.
