ABSTRACT:
A method of producing a pulp molded article. The method feeds a pulp slurry to a cavity of a papermaking mold having a prescribed cavity shape to form a pulp preform including a main part having an opening and a separable part having a flange and connected to an edge of the opening. A pressing member is inserted into the preform, the pressing member is expanded to press the preform toward the papermaking surface, the preform is removed from the papermaking mold, and then the preform is cut at a joint between the separable part and the main part.
