A rail-shaped water-removal element for the wet stage of a water-removal machine, in particular a paper-making machine, such as a mesh table, foil, couch roll, wet suction roll, suction roll, suction tube and suction felt is so shaped that the layer that is in sliding contact with the mesh or felt consists of individual segments of hard material such as sistered aluminum oxide and silicon carbide. These segments having devices for the installation of profile rails that extend transversely to the direction of movement felt or mesh of the machine, the individual segments having at the ends of their longitudinal sides stepped jointing surfaces that extend across the whole width of the segments and are cemented to each other at these jointing surfaces. |
