ABSTRACT:
In a device for making shaped objects from plastic refuse plasticized in a roller extruder under pressure and ejected from the nozzle of the extruder a plurality of molds are provided transported to the extruder, filled thereby and transported therefrom. Each mold has at the end face a plate having a filling opening. During the filling process this plate sealingly overlaps the surface surrounding the nozzle so that the mold can be filled with plasticized plastic under the pressure generated in the roller extruder.
