Abstract

UNA CAJA DE PASTA (20) QUE TIENE UN HAZ DE TUBOS (28) CON LOS TUBOS (26) DISPUESTOS EN FILAS EN LA DIRECCION DE LA MAQUINA. LOS TUBOS (26) SE EXTIENDEN DESDE LA PARED DE EVACUACION (30) DE UN CABEZAL HASTA EL ORIFICIO DE ADMISION DE UNA TOBERA (42). LAS PAREDES SUPERIOR E INFERIOR (44, 46) DE LA TOBERA (42) CONVERGEN HACIA EL ORIFICIO DE EVACUACION DE LA TOBERA (48) Y UNOS PLANOS QUE SE EXTIENDEN DESDE LAS PAREDES (CUBIERTA Y MANGUITO DE LA TOBERA) CONVERGEN PARA DEFINIR UNA LINEA CENTRAL IMAGINARIA QUE SE EXTIENDE EN LA DIRECCION TRANSVERSAL A LA MAQUINA. LAS FILAS DE TUBOS (26) ESTAN DISPUESTAS A LO LARGO DE UNOS PLANOS QUE SE EXTIENDEN RADIALMENTE DEFINIDOS RESPECTO A LA LINEA CENTRAL. LAS EXTREMIDADES DE INYECCION DE LOS TUBOS DEFINEN UNA SUPERFICIE CILINDRICA (64) QUE SE EXTIENDE ENTRE LAS PAREDES DE LA TOBERA (44, 46). EL MATERIAL QUE SALE DE CADA TUBO (26) ES DIRIGIDO RADIALMENTE HACIA LA LINEA CENTRAL A LO LARGO DE UNOS CONDUCTOS DE FLUJO (47) DE IGUAL LONGITUD. PUEDE HABER UNOS ALABES ARRASTRADORES (68) COLOCADOS ENTRE LAS FILAS DE TUBOS (26) PARA QUE ASI EL FLUJO ENCUENTRE UNAS CONDICIONES DE LIMITE DEL FLUJO CASI IDENTICAS AL FLUIR HACIA EL ORIFICIO DE EVACUACION DE LA TOBERA (48), CONTRIBUYENDO ASI A LA OBTENCION DE UNA ORIENTACION MAS UNIFORME DE LAS FIBRAS EN LAS HOJAS CONTINUAS DE PAPEL RESULTANTES (51).
