Abstract

See full text

The present invention includes a system of multipart devices for the formation, pressing, and coating of molded pulp fiber articles. The system includes a mold device, a pressing device, and/or a coating device. Each device comprises a screen fastened or otherwise connected to the housing unit. The housing unit is a solid, non-porous housing element, and multiple housing units are configured to be reversibly connected to form a single device. When joined together, the screens of each housing unit form a continuous cavity for the molding, pressing, and coating of the product. The housing unit of a mold device comprises one or more vacuum systems which direct vacuum pressure to the product surface of the mold screen to form a pulp fiber product from a pulp fiber slurry. The pulp product is operable to be dried in the mold device, resulting in the formation of a stable, thin-walled pulp product.
