ABSTRACT:
A fiber classifying mechanism and method including a first chamber having an inlet for receiving fibers to be classified carried in a fluid suspension and having an outlet from the same chamber. A second chamber receives a controlled split of flow from the first chamber through a screen between the chambers having openings of a size to pass reject fibers. Means are provided for controlling the split of flow by a valve in the outlets from the respective chambers so as to control the flow through the screen. A foil moves past the screen to agitate fibers collected on the surface of the screen.
