Zusammenfassung: | A molding apparatus for patterned shaped articles comprises a form (M) constituted of at least one partition member (1) defining the boundary of the pattern to be produced, a peripheral frame (2) surrounding the partition member at a prescribed spacing therefrom and a cover (3) for closing the upper ends of the partition member and the peripheral frame; at least one feed port (5A) for supplying particles into a pattern space (4A) enclosed by the partition member; at least one suction port (18A) for sucking particles out of the pattern space (4A); at least one feed port (5B) for supplying particles into a pattern space (4B) between the partition member and the peripheral frame; at least one suction port (18B) for sucking particles out of the pattern space (4B); charging means (7, 9) for supplying particles to at least one of the pattern spaces by compressed air, and suction means (20) for sucking particles from the pattern spaces. |
