Abstract
A method and apparatus for use in the manufacture of improved molded pulp products are disclosed wherein foraminous molds disposed over openings in a liquid impervious belt are moved beneath the surface of a flowing furnish and suction is applied to draw liquid through the molds and deposit a layer of pulp on each mold. Thereafter, the pulp deposit on each mold is simultaneously subjected to a generally uniform pressing with a second belt and suction which forms a smooth exposed surface on the pulp deposit and removes a portion of the liquid therein.
