Sorting screen for fibre suspensions comprising a screen wall having recesses on a first side and narrower sorting apertures on the other, second side, these apertures opening into the recesses and the recesses each extending over a plurality of sorting apertures and being spaced in all directions from one another such that the screen wall has a net structure on its first side between the apertures. In order to achieve the utmost fineness when sorting with such a screen the recesses are arranged on the inflow side of the screen wall and the sorting apertures are designed as bores. |
