Zusammenfassung:A screening machine for a fiber suspension includes a vessel; a rotor disposed within the vessel; and a screen plate positioned in stationary opposition to the rotor. The screen plate includes a plurality of substantially parallel first grooves extending in a first direction and a plurality of substantially parallel second grooves extending in a second direction. The first grooves intersect with the second grooves. The first grooves and the second grooves conjunctively define a plurality of lands and depressions. A plurality of the lands and a plurality of the depressions include a through-hole extending through the screen plate.
