Abstract

DISPOSICION DE UNA DISTRIBUIDORA DE PASTA PARA MAQUINAS DE FABRICAR PAPEL DE VARIAS CAPAS. LAS CAMARAS PARCIALES (7) SE ENCUENTRAN EN COMUNICACION A TRAVES DE LOS CANALES DISTRIBUIDORES (2) CON DIVERSAS CONDUCCIONES DE ENTRADA, SOBRESALIENDO EL ELEMENTO SEPARADOR (4) POR LA RANURA DE SALIDA DEL CANAL PULVERIZADOR (6). SE PUEDEN ALIMENTAR ASI LAS CAMARAS PARCIALES CON PASTAS DE DIVERSAS CALIDADES, EVITANDOSE CON LA DISPOSICION DEL ELEMENTO SEPARADOR SOBRE EL INTERSTICIO DE LA SALIDA (8) UNA PREMATURA MEZCLA DE LAS DIFERENTES CAPAS, INTERRUMPIENDOSE DE ESTA MANERA EL TRANSPORTE DE LA SUSPENSION A UNA DE LAS CAMARAS PARCIALES O BIEN TRANSPORTANDOSE A UNA O VARIAS DE LAS CAMARAS DE SUSPENSION MEZCLADAS CON AIRE EN FORMA DE ESPUMA.LAYOUT OF A PAPER DISTRIBUTOR FOR MULTI-LAYER PAPER MAKING MACHINES. THE PARTIAL CHAMBERS (7) ARE IN COMMUNICATION THROUGH THE DISTRIBUTOR CHANNELS (2) WITH VARIOUS INPUT PIPELINES, PROJECTING THE SEPARATOR ELEMENT (4) THROUGH THE OUTLET SLOT OF THE SPRAYER CHANNEL (6). THE PARTIAL CHAMBERS CAN THUS BE FEED WITH PASTE OF DIFFERENT QUALITIES, A PREMATURE MIXING OF THE DIFFERENT LAYERS IS AVOIDED BY THE ARRANGEMENT OF THE SEPARATOR ELEMENT OVER THE INTERSTICE OF THE OUTLET (8), THUS INTERRUPTING THE TRANSPORTATION OF THE SUSPENSION TO ONE OF THE PARTIAL CHAMBERS OR TRANSPORTED TO ONE OR MORE OF THE SUSPENSION CHAMBERS MIXED WITH AIR IN THE FORM OF FOAM.
