A flat or cylindrical screen includes rods and rod-bearing supporting elements. The rods have protrusions in the side walls which are received into inversely shaped recesses in a supporting element. The screen is manufactured by bending the supporting elements open elastically and inserting the rods, whereupon the supporting elements spring back, encircle the rods positively and form a screen mat.

Screen and process for manufacturing a screen of this kind

A screen for cleaning a pulp suspension including an additional screen basket in the infeed area for pre-screening.

Screen

A screen for cleaning a pulp suspension includes a stationary installation in the infeed area between the infeed branch and the free end of the rotor.

Screen for cleaning a pulp suspension

A screen, for screening material used in the production of paper, board and the like, having a screen basket and a rotor supporting several blades which can be moved along the wall of the screen basket when the rotor rotates. The blades having a convex curvature on the side facing the screen basket. The radial clearance between the surface of the blade facing the screen and the screen being lowest between the front sector, viewed in the direction of rotation, and increasing towards the rear edge of the blade.

Screen for pulp processing

A screen for cleaning a pulp suspension including a cylindrical screen basket and a double-conical accept chamber which widens in the flow direction of the pulp suspension.
