Abstract
La presente invención se refiere a un procedimiento para fabricar un producto absorbente que comprende parcial o totalmente una borra de materiales finamente divididos, caracterizado porque comprende los pasos de: (a) proveer un formador que tiene una pluralidad de aberturas en él; (b) suministrar una banda continua, movible, de material permeable al flúido a un lado del formador para cerrar ese lado de las aberturas del mismo, de una manera permeable al flúido; (c) aplicar una diferencia de presión a través del formador para hacer que el lado de menor presión se forme en un lado del formador y se forme un lado de mayor presión en el otro lado del formador, con un flujo de flúido a través de las aberturas y a través del material permeable al flúido que cierra las aberturas; (d) introducir por lo menos dos corrientes de entrada de flúido en el lado de alta presión, desde lados opuestos tranversalmente con respecto a la dirección de movimiento de la banda continúa, por lo menos una de las corrientes conteniendo materiales finamente divididos suspendidos en ella; (e) permitir que los materiales finamente divididos pasen hacia las aberturas y sean depositados sobre la banda continua de material permeable al flúido; (f) y hacer que la banda de material permeable al flúido con la borra de material finamente divididos sobre ella se separe del formador.
