Abstract:
Method of producing molded glass bodies in accordance with the press-molding method, in which a feeder is used to pour a predetermined quantity of molten glass into a press mold, which determines the external shape of the molded glass body and into which the predetermined quantity of molten glass is pressed with the aid of a molding plug that determines the internal shape of the molded glass body and is pressed into the mold from an initial position outside of the press mold during the pressing process, the improvement comprising pouring a predetermined quantity of molten glass into the press mold located in the pressing station before the molding plug is pressed therein, pressing the molding plug into the molten glass according to a predetermined temporal dependency on force and feed withdrawing the molded glass body from the press mold located in the pressing station after withdrawing the molding plug, and that for pouring in the predetermined quantity of molten glass and for withdrawing the molded glass body, pivoting the molding plug laterally from its inoperative position about an axis extending transversely to the longitudinal axis of the molding plug, displacing a feeder chute connected to the feeder from an initial position that allows the molding plug be pressed into the press mold for filling the press mold with a predetermined quantity of molten glass while or after the molding plug is pivoted into a position in which the end of the feeder chute communicates with the opening of the press mold and further pivoting the line back to its initial position after completion of the filling procedure.
