ABSTRACT:
A papermaking apparatus such as a Fourdrinier table which includes a long blade and a trail blade. In the first aspect of the invention, the long blade includes an upper undulated surface with vents passing from the upper undulated surface to the lower surface of the long blade which is at substantially atmospheric pressure. In the second aspect of the invention, the trail blade includes an elevator-type device for adjusting the vertical position of the trail blade. The first and second aspects may be used independently or simultaneously.
