PURPOSE:To enable continuous and smooth extrusion through a die and to stabilize the rate of extrusion, by inserting a drill-like cutter in the inner surface of a die or in a nozzle of a twin screw extruder and rotating the cutter. CONSTITUTION:An object to be treated is processed in a twin-screw extruder and extruded through a die 10 attached to the delivery end of the extruder. In the above process, a drill-like cutter 7 is rotated on the inner surface of the die or in the nozzle of the die to continuously scrape off the object on each part and prevent the clogging of the die 10. The extrusion through the die 10 can be continuously and smoothly carried out and the rate of extrusion can be stabilized by this process. |
