摘要： The invention is extrusion equipment and a process. The extrusion equipment links two extruders (11, 15) together. The first extruder (11) is, desirably, a counter-rotating twin screw extruder. The first extruder (11) receives organic filler, preferably wood particles or fiber, having a variable moisture content. Moisture is withdrawn from the extruder barrel. A polymer is fed from a second extruder (15) into the barrel of the first extruder (11) after the polymer is heated, mixed, and melted in the second extruder (15). The second extruder (15) can be a single screw or twin screw extruder. The combined mixture of organic filler and polymer is further mixed alone or with optional additives. The mixture is vacuum vented to remove moisture and volatiles and then extruded through a die. Additional processing steps are optional depending upon the extruded product or profile being produced.

摘要： The invention is a method for operating an extruder temperature controller. The method can include sensing an actual screw speed for an extruder screw in an extruder barrel. The extruder barrel has at least one heat exchange means. The method can then involve indexing and storing a plurality of screw speeds. Each of the stored screw speeds corresponds to a temperature reset value. Comparing the actual screw speed with each of the stored screw speeds can then be performed. Selecting one of the stored screw speeds can then occur. The selected screw speed is a member of the plurality of stored screw speeds having a value most arithmetically equivalent to the actual screw speed. The step of selecting retrieves the temperature reset value corresponding to the selected, stored screw speed. Generating a control output driver signal to the heat exchange means can occur. The control output driver signal is responsive to the retrieved temperature reset value. The invention includes delaying a control alarm for a predetermined time when generating a control output driver signal to the heat exchange means is at or near maximum capacity.

摘要： A rotating combination thrust plate and thrust shaft flange (10), and a thrust bearing assembly (40) incorporating the rotating flange plate combination (10), in which the rotating flange plate combination (10) has a generally cylindrical body portion (22) which has a rotating base surface (24) and a lateral surface (23), a frustoconical body portion (29) which has a frustoconical surface (28), and a bore (12) extending through the cylindrical and frustoconical body portions (22 and 29) and having a first bore section (14) and a second bore section (16) wherein the second bore section (16) is adjacent the rotating base surface (24) and has a smaller diameter then the first bore section (14). The first and second bore sections meet at a junction (18) defining a lip (21) which is designed to support a complimentary lip (42) of a bore shaft (20) thereby restricting the movement of the bore shaft (20) in the direction of thrust in an extruder.
