Abstract: An apparatus for manufacturing a molded item having a corner is provided. The apparatus includes a mold support for holding an angled mold having an inside corner. A hopper having an outside corner that corresponds to the inside corner of the mold and a screen at the outside corner mates with the mold. A vibration device is provided for causing a material contained in the hopper to pass through the screen, such as by applying a predetermined force for a predetermined period of time required to fill the mold. Different sized openings in the screen combined with the flowability of the material and the amount of vibration can determine how much material flows through the screen.
