ABSTRACT:
A method to simultaneously de-water and form a sheet of pulp is disclosed. The method employs a pair of wire meshes, the meshes being adapted to move continuously under tension and to receive pulp continuously from a stock inflow tank. A layer of pulp is subjected simultaneously to progressive mechanical compression and to aspiration of the water at a constant value owing to a siphon effect. Also disclosed is an apparatus to carry out this method.
