  • Method and apparatus for achieving optimum discharge from a twin-screw extrusion device
    Patent number: 4550002
    Abstract: A method and apparatus for regulating a dose-charged twin-screw extrusion device so as to achieve optimum quantitative discharge of a material being extruded in an automatic manner. By monitoring the screw torque and the mass temperature and modifying the dosed supply of material and/or the screw speed in accordance with the monitored values, the optimum mode of operation is ensured for the extrusion device which fully utilizes the discharge capacity of the device without risking damage either to the extrusion device itself or to the material being extruded.
