Abstract In a screen consisting of a supporting frame (1) which is covered with apertured (6) screen elements (2) of resilient material, said screen elements (2) are well supported and particularly easy to replace without intervention, e.g. by way of welding, as they have longitudinal guide grooves (7) which have a profile serving to be snapped on to the upper layer (3) of the supporting frame (1) and such a depth that the lower layer (4) of the supporting frame (1) engages the underside of the screen elements (2). In a preferred embodiment the wires or bars in the lower layer (4) of the supporting frame are disposed so as to be out of alignment with the apertures (6) of the screen elements so that also the wires in this layer are protected against wear.
