    摘要： The invention includes a method and an extrusion apparatus for shaping plastic materials particularly those of high molecular weight, whereby the temperature distribution in an extrusion cylinder allows for the build-up of very high pressures and all axial pressure forces are absorbed by a two-sided extruder screw, the extrusion cylinder and, in some instances, the therein contained plastic material. In practicing the method, the plastic material in a flowing state, and at a positive pressure, is continuously conveyed to an extrusion apparatus, and subsequent to its entrance in an extrusion cylinder and before its discharge is cooled to a temperature below the solidification point, not only from the outside by a cooling source in the extrusion cylinder but also from the inside by a cooling source in the interior of the extruder screw.The present invention makes possible the production of materials of improved strength and elasticity, which can be molded to synthetic threads, films and splittable films.

    摘要： A MACHINE FOR PLASTICIZING AND EXTRUDING PULVERULENT THERMOPLASTIC OR DUROPLASTIC MATERIAL HAS A FIRST STAGE WITH A BARREL FOR TWO INTERMESHING PLASTICIZING AND METERING SCREWS WHICH CONVEY PLASTIC MATERIAL FROM THE CENTER TOWARD BOTH ENDS OF THE BARREL AND A SECOND STAGE HAVING A BARREL FOR ONE OR TWO EXTRUDING SCREWS WHICH SERVE TO CONVEY PLASTICIZED MATERIAL FROM THE ENDS TOWARD A DISCHARGE OPENING IN THE CENTER OF THE RESPECTIVE BARREL. THE ENDS OF THE BARREL IN THE SECOND STAGE COMMUNICATE WITH THE ENDS OF THE BARREL IN THE FIRST STAGE. THE DRIVE FOR THE

    SCREWS HAS A SINGLE ELECTRIC MOTOR WHICH ROTATES THE SCREWS BY WAY OF GEAR TRANSMISSIONS WITH INTERCHANGEABLE GEARS. THE SCREW OR SCREWS OF THE SECOND STAGE TRANSMIT TORQUE TO THE SCREWS OF THE FIRST STAGE AND THE SCREW OR SCREWS OF THE SECOND STAGE CAN BE REMOVED OR REINSERTED BY MOVING AXIALLY THROUGH A GEAR OF AT LEAST ONE OF THE TRANSMISSIONS WHICH DRIVE THE SCREWS OF THE FIRST STAGE. THE BARREL OF THE FIRST STAGE CAN BE OPENED LENGTHWISE TO AFFORD ACCESS TO THE RESPECTIVE SCREWS.

    摘要： A DEVICE FOR THE PRESSURELESS PLASTICATION OF POWDERY PLASTIC MATERIALS, WHICH CAN BE USED IN FRONT OF A CONVENTIONAL SINGLE SCREW EXTRUDER, AND WHICH INCLUDES TWO AXIALLY PARALLEL SCREWS, LOCATED IN A HOUSING AND HAVING AN ESSENTIALLY IDENTICAL FLIGHT GRADIENT, WHICH ALMOST COMPLETELY ENGAGE INTO EACH OTHER AND CAN BE ROTATED IN THE SAME DIRECTION. EACH SCREW IS SHAPED TO PROVIDE SEALING RIDGES WHICH CLOSE THE CONVENTIONAL SCREW THREADS AND

    WHICH ENGAGE WITH CORRESPONDINGLY SHAPED PASSAGEWAYS PROVIDED IN THE FLIGHTS OF THE ADJACENT SCREW, WHEREBY THE PLASTICATION CAN BE CARRIED OUT WITH ONLY PARTIALLY FILLED SCREW THREADS, AND A CONSTANT SEALING ENGAGEMENT OF THE SCREWS IS INSURED. THE TRAPPED AIR AND THE DEVELOPING GASES CAN ESCAPE THROUGH VAPOR OUTLETS PROVIDED IN THE HOUSING.

    摘要： The invention relates to an apparatus for extruding thermoplastic material, comprising an extruder screw (2) which is mounted in a housing (1), comprises a plasticizing section (P) on the inlet side, a degasification section (E) upstream of an outlet section (A), a flow arrester (S) between the plasticizing section (P) and the degasification section (E) with a screw section with a counter-rotating delivery flight (3), and at least one flow channel (5) bridging the flow arrester (S) and containing a melt filter (4). In order to reduce the driving power of the extruder screw (2) it is proposed that a sleeve (7), which encompasses the screw (6) and is mounted in the housing (1) in a rotationally fixed manner, is associated with the screw section that forms the flow arrester (S), and the screw (6) in the screw section of the flow arrester (S) has a smaller screw diameter in relation to the plasticizing section (P) and preferably also to the degasification section (E).

    摘要： An apparatus is provided for extruding a polymer which is subject to periodic surges. The apparatus includes a barrel with an upstream portion for receiving polymer, a downstream portion and a discharge port near the downstream portion. The apparatus also includes a shaft mounted for rotational movement about a longitudinal axis within the barrel as well as drive means connected to rotate the shaft. The apparatus has a surge suppressor for urging polymer upstream toward the discharge port while permitting a portion of polymer to flow downstream into the surge suppressor. A sensor is positioned within the apparatus to detect surges in the polymer and a controller is connected to the sensor and to the drive means for adjusting shaft rotation in response to polymer surges.
