Abstract

A blade for a screening apparatus, especially for fiber suspensions during pulping, has an outer contour profile adjacent a facing screen wall to form in fluid flow direction a suction zone section of increasing width of the blade and a pressure zone section of decreasing width of the blade, whereby the length of the suction zone section and the length of the pressure zone section together form the overall length of the blade, and whereby the outer contour profile exhibits a continuous configuration also in a transition area between the suction zone section and pressure zone section.
