    摘要: 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.

    摘要: Disclosed is a method of producing a fiber-molded hollow article by using a papermaking mold (2) composed of splits (21, 22) which are joined to form a cavity (20) having two openings (20a, 20b) connecting with the outside and an expandable pressing member (3) adapted to be placed in the cavity (20). The method comprises the steps of immersing each of the splits (21, 22) before being joined in a fiber slurry to form a fiber preform (10a, 10b), joining the splits (21, 22) each having the fiber preform (10a, 10b) formed thereon while placing the pressing member (3) in the cavity (20), and molding and dewatering a molded article (1) in the papermaking mold (2).
