Abstract

Método de utilizar el desperdicio que se origina por fraccionación del papel de recuperación, en la industrial del papel, caracterizado porque el papel de recuperación se somete a una fraccionación, se separa la fracción de fibras largas y el desperdicio, constituido por la fracción de fibras cortas y las cargas, se regenera la fracción de fibras largas por desmenuzado, ventajosamente por desmenuzado de desfibración, hasta los valores mecánicos requeridos, y se devuelve después por lo menos una parte del desperdicio previamente separado a la fracción de fibras largas, hallándose comprendida la cantidad de desperdicio devuelta desde la fraccionación entre 10 y 100 por ciento del desperdicio separado.
