Number: 162/387
Name: Paper making and fiber liberation > Apparatus > Foraminous forming mold for discrete articles (pulp molding) > Accretion from bulk (i.e., immersed mold)
Description: Apparatus in which a foraminous forming surface is brought into contact with an excess of pulp slurry and that amount of fibers necessary to form the completed article are deposited on the mold by difference in pressure between the back surface of the foraminous mold and the supply of pulp, and the mold with the fiber layer thereon is then removed from the body of the pulp slurry.
