摘要： A process and an apparatus for continuously producing a rubber mixture. In the process, the constituents of the mixture are fed into a twin-screw extruder and are masticated and homogenized therein, with approximately 5% of the mixture being discharged and the remainder being recycled for further homogenization and for mixing with fresh batches of the constituents being fed into the extruder. The recycled mixture is circulated to and returned from a cooled, annular chamber dispersed exteriorly of the chamber of the twin-screw extruder, with the annular chamber having outflow and inflow passages communicating with the interior of the extruder.

摘要： A single or twin-screw device is used to incorporate additives in a thermoplastic plastics material melt. The or each barrel of the extruder includes a first feed aperture for the introduction of the melt and a second feed aperture downstream thereof for the introduction of the additives. A screw is mounted on a shaft in each barrel and includes a core and a helical flight. In the region of the second feed aperture, the flight is replaced by alternating disc members and spacer members mounted on the shaft. The diameter or major dimension of the disc members is approximately equal to the combined diameter of the screw core and its flight while the diameter of the spacer members is approximately equal to that of the screw core. The disc members have profiled downstream faces. The disc and spacing members increase mixing and consequently throughput in the region of the second feed aperture.

摘要： An extruder for degassing a thermoplastic plastics material melt comprises at least one screw mounted for rotation in a barrel. The barrel includes a first feed aperture for the introduction of the melt and a degassing port downstream thereof connectable to means for degassing the melt. The at least one screw is mounted on a shaft and has a helical flight. In the region of the port, the flight is replaced by alternating disc members and spacer members mounted on the shaft. The diameter or major dimension of the disc members corresponds substantially to the combined diameter of the screw core and its flight whilst the diameter of the spacer members corresponds to that of the screw core. The disc members have profiled downstream faces and the thickness of each disc member and each spacer member lies in the range of 0.1 to 0.5 times the diameter of the screw.

摘要： A back-pressure bearing arrangement for a twin-screw extrusion device which prevents any back-pressure forces from affecting a gear arrangement used for driving the screws. By disposing the back-pressure bearings between the gear arrangement and the housing of the extrusion device and by providing a bearing plate, which is supported by adjustment bolts or tension rods, the bearings are frictionally disconnected from the gear arrangement housing and the back-pressure forces of the screw shafts are effectively prevented from adversely affecting the gear arrangement.
