Abstract

Perfeccionamientos en cribas para máquinas de fabricar papel, para tratar pasta que fluye a una cabeza principal caracterizados por comprender en combinación: una caja que define una cámara de cribado que posee una abertura de entrada para la pasta; una criba cilíndrica situada dentro de la cámara para que la pasta pase a través de ella a la pared exterior de la cámara; unos medios de hojas montados para que giren a velocidad uniforme desplazándose a lo largo de dicha criba a fin de engendrar pulsaciones en la pasta que pasa a través de la criba; una transmisión para mover los medios de hojas a lo largo de criba; una pluralidad de salidas dispuestas circunferencialmente alrededor de la pared exterior de la caja que recibe la pasta después de que haya pasado a través de la criba; y un colector que conduce a una cabeza principal y al que están conectadas dichas salidas, estando dispuestas éstas de modo que las pulsaciones provocadas por los medios de hojas tienden a anularse en el colector.
