Abstract

UN CONJUNTO DE CRIBA PARA INSTALAR SOBRE EL EXTREMO DE SALIDA UN EXTRUSOR QUE ELIMINE PARTICULAS EXTRAÑAS DE UN MATERIAL ELASTOMERICO QUE SE ESTA DESCARGANDO DEL EXTRUSOR. EL CONJUNTO INCLUYE UN ELEMENTO DE SOPORTE DE LA CRIBA, QUE TIENE UNA PLURALIDAD DE PESTAÑAS ALARGADAS Y ESPACIADAS, FORMADAS INTEGRAMENTE CON, O EXTRAIBLEMENTE MONTADAS SOBRE, UN ELEMENTO CIRCUNDANTE. LAS PESTAÑAS ESPACIADAS FORMAN UNA PLURALIDAD DE RANURAS ALARGADAS ENTRE ELLAS, QUE PROPORCIONAN PASOS DE FLUJO PARA EL MATERIAL ELASTOMERICO Y, PREFERENTEMENTE, TIENEN FORMA CONCAVA EN LA DIRECCION DEL RECORRIDO DEL MATERIAL EXTRUSIONADO. UNA CRIBA DE MALLA FORMADA POR UN PAÑO DE ALAMBRE DE ACERO INOXIDABLE, ENDURECIDO POR ACRITUD Y DE GRAN RESISTENCIA A LA TENSION, SE FORMA COMPLEMENTARIAMENTE A LA CONCAVIDAD DE LAS PESTAÑAS, Y SE INSTALA EN YUXTAPOSICION A LAS PESTAÑAS PARA EXTRAER LAS PARTICULAS EXTRAÑAS, A MEDIDA QUE EL MATERIAL ELASTOMERICO PASA A TRAVES DE LA CRIBA. LA CONCAVIDAD DE LAS PESTAÑAS Y LA FORMACION DE LOSPASOS DE FLUJO ALARGADOS DEL MATERIAL REDUCEN LA PRESION POSTERIOR CREADA EN EL MATERIAL ELASTOMERICO, Y REDUCEN LAS FUERZAS DE CURVATURA Y CORTE CREADAS SOBRE LAS PESTAÑAS Y ELEMENTO DE SOPORTE CIRCUNDANTE.
