Abstract

PROCEDIMIENTO DE EXTRUSION Y EXTRUSIONADO DE UNO , DOS O VARIOS TORNILLOS SIN FIN. EN EL EXTRUSIONADO LA TUERCA DEL TORNILLO SIN FIN O CADA UNO DE LOS TORNILLOS SIN FIN PASAN EN PARTE A LA IZQUIERDA Y EN PARTE A LA DERECHA, DE MODO QUE EL MATERIAL A ELABORAR SE TRANSPORTA EN PARTE EN UNA DIRECCION A Y EN LA OTRA PARTE EN UNA DIRECCION B CONTRAPUESTA . EL PROCEDIMIENTO ES UN PROCEDIMIENTO DE EXTRUSION DE DESGASIFICACION Y EL EXTRUSIONADO ES UN EXTRUSIONADO DE DESGASIFICACION. ESTA PREVISTO: - UN DISPOSITIVO DE DESGASIFICACION HACIA ATRAS (7, 22) EN EL EXTREMO (8, 19) DEL TORNILLO SIN FIN (1, 16) O TORNILLOS SIN FIN (1, 16) SI SE SACA FUERA EL MATERIAL A ELABORAR DE ESTOS EXTREMOS (8, 19) Y/O - UN DISPOSITIVO DE DESGASIFICACION HACIA ATRAS (41, 52) EN EL LUGAR ENTRE LOS SEGMENTOS ROSCADOS DEL TORNILLO SIN FIN (1, 16) O TORNILLOS SIN FIN (1, 16) DE DONDE SE SACA EL MATERIAL A ELABORAR EN DIRECCION B Y A CONTRAPUESTAS. SEGUN EL INVENTO: -ES POSIBLE UN FUNCIONAMIENTO CONTINUO; - NO SE FORMANNINGUNA ZONA MUERTA NI CANTOS DE DESGARRAMIENTOS; NO SE CIERRA ESTANCAMENTE EL DISPOSITIVO DE DESGASIFICACION HACIA ATRAS (7, 22, 41, 52) FACILMENTE CONTRA LA ENTRADA DE OXIGENO; - PUEDEN ELABORARSE TAMBIEN PRODUCTOS SENSIBLES TERMICA Y OXIDATIVAMENTE, COMO POLIAMIDA 66 SIN DAÑOS Y CON DURACION DE FUNCIONAMIENTO (POR EJEMPLO FIBRA SINTETICA - HILADO DE EXTRUSION).
