Title: PAPER MOLDING MANUFACTURING METHOD AND DEVICE THEREFOR
Abstract:
Provided are a paper molding processing method, which does not allow the generation of discernible wrinkles in the upright portion of the paper molding in the processing of a paper molding in which a single blank having paper as the main component is drawn using a punch and a die, and a manufacturing device that executes same. This paper molding manufacturing method is characterized in that when a sheet-shaped blank (9) having paper as the main component is drawn using a punch (7) and a die (3), the generation of wrinkles is limited by the coordination of functions acting on the blank in two regions, the functions resulting from maintaining a fixed gap between a first wrinkle-limiting member (1) and the die on a region in the outer periphery of the portion of the blank to be processed while applying a pressing force via a second wrinkle-limiting member (2) on a region to the inside thereof.
