Method of manufacturing pulp mold formed body

摘要

A method of producing a pulp molded article is disclosed. The method comprises the steps of: feeding a pulp slurry to a cavity (4) of a papermaking mold (1) having a prescribed cavity shape to form a pulp preform (7) comprising a main part (7a) having an opening and a separable part (7b) having a flange (7c) and connected to the edge of the opening; inserting a pressing member (8) into the preform (7); expanding the pressing member (8) to press the preform (7) toward the papermaking surface; removing the preform (7) from the papermaking mold (1); and then cutting the preform (7) at a joint between the separable part (7b) and the main part (7a).
