Abstract
In a method for producing a molded plastic article, individual portions of material are removed from a flow of heat-plasticized material which flows vertically downwards from a closable dispensing aperture of a dispenser and are transferred to a mold before being pressed by closure of the mold to form a molded article. The required portions are cut by cutting shears from the flow of material at a point below the dispensing aperture and at a distance from it. A device for the production of the molded plastic article has a closable mold and a material dispenser for heat-plasticized synthetic material which can be arranged above the molding chamber. The dispenser has a dispensing aperture which points towards the mold and can be closed by a closure unit and from which the flow of plasticized material emerges. A shearing device for separating the required portions of material is situated below and at a distance from the dispensing aperture.
