Abstract (en)

[origin: EP0414119A1] A screening cylinder for the grading of fibre suspensions has, on the outside, slot-shaped grooves (2) which are formed arcuately with higher curvature on the downstream flank (4) and with lower curvature on the upstream flank (5); the screening orifices (6) open into the slot-shaped grooves (2) approximately at the lowest point. In a modified embodiment of a screening cylinder of this type, the slot-shaped grooves (2) are formed arcuately with higher curvature on the downstream flank (4) and with lower curvature on the upstream flank (5); the screening orifices (6) open into the flank (5) of lower curvature. <IMAGE>
