ABSTRACT:
A screen apparatus for paper making capable of substantially fully recovering fibers from a paper feedstock which has been subject to a pulper and discharging a residue while dehydrating it. A paper feedstock is subject to two-stage maceration and two-stage screening through first and second screen chambers each provided therein with a screen and macerating blade combination. The screens are each cleaned by the macerating blades, so that fiber pieces contained in the paper feedstock are substantially fully recovered with high efficiency and a residue is discharged while being substantially free of fiber pieces and substantially dehydrated.
