ABSTRACT:
A papermaking machine has a dewatering mesh that passes over and is supported by a plurality of parallel dewatering bars extending transversely of the displacement direction of the mesh. Each bar has an elongated ceramic upper surface formed with a sharp front edge directed into the mesh displacement direction and each bar is carried on and displaceable along a transversely extending support guide so that it can be drawn transversely out from underneath the mesh and can be reinserted transversely thereunder. The upper surface and the sharp front edge of the bar are rounded at one end of the bar so that this bar can be displaced transversely under the mesh with this one end out of contact with the mesh during the operation of the machine and passage of the mesh over the sharp edge of the guide bar.
