|20100203184||Extruder Stabilizer Assembly - A stabilizer assembly for use in an extruder having a screw rotating in a barrel is provided. The assembly comprises a plurality of rods that are secured to an interior of the barrel at one end. Each of the rods has an end that extends radially inwardly toward the center of the barrel. On the discharge end of the screw, there is a bearing member that is in contact with each of the opposite ends of the rods. The rods support the discharge end of the screw and stabilize its rotation in the barrel.||08-12-2010|
|20090291159||Support Assembly for an Extruder - A modular base is provided. A plurality of motor support members are secured to one another by a first linking member. Each motor support member has a mounting surface that is adapted to be secured to a motor, and the first linking member has a central axis and is dimensioned to support the motor. A plurality of extruder support members are secured to one another by a second linking member. Each extruder support member has a carriage that is adapted to be secured to an extruder, wherein the second linking member has a central axis and is dimensioned to support the extruder. An intermediate member having a mounting surface that is adapted to be secured to a transmission is provided. The intermediate member is secured to one of motor support members by the first linking member and secured to one of the extruder support members by the second linking member, wherein the central axes of the first and second linking members displaced from one another at a distance that enables the transmission to transfer mechanical work from motor to the extruder.||11-26-2009|
|20090268550||Extruder Screw With Long Wearing Surfaces - A method of extending the life of an extruder screw by affixing tiles of wear-resistant material along the crest of the extruder screw flighting threads, and optionally grinding the hardened material to remove any sharp edges. In another configuration of the present invention, plates of wear-resistant material are secured to the leading edges of the extruder screw threads to further prolong the life of the extruder screw.||10-29-2009|
|20090258103||Multi-Head Extruder Assembly - An extruder that is adapted to provide a flow of an extrudate is provided. There is a frame having a plurality of storage positions, a discharge position and a plurality of extruder heads. Each extruder head is secured to the frame and is movable between one of the storage positions and the discharge position. A sealing member is provided that is secured to the extruder. The sealing member is adapted to move between an engaged position and a disengaged position, wherein the sealing member moves from the disengaged position to the engaged position so as to engage one of the extruder heads when it is in the discharge position.||10-15-2009|
|20090258100||Thermal Growth Compensating Extrusion Screw Assembly - An improved extrusion assembly is disclosed which better adapts to thermal changes resultant from the transport of high-temperature extrudate. An extrusion screw present in the assembly includes a hollow portion. A biasing member is disposed in the hollow portion. When the assembly is transporting high-temperature extrudate, the biasing member's included Belleville washer component compensates for the thermal expansion and contraction of the extrusion screw.||10-15-2009|
|20090252628||Sealing Rings for Abrasive Slurry Pumps - There are a number of applications today where the pumping of abrasive slurries is necessary. The pumping mechanisms, though, can be complex, employing multiple transfer cylinders and movable pipes. These designs have their problems, specifically wear between poorly sealing surfaces. To reduce this problem, seals are provided that have multiple wear surfaces which include harder tiles secured over a softer core to benefit from the relative hardness or flexibility of each of the respective materials.||10-08-2009|
|20090249934||Apparatus and Process for Cutting of Extruded Material - A rotating cutting apparatus comprising a cutting blade holder with at least one hole on the outside diameter of the cutting blade holder into which cutting blades are inserted and bonded to the cutting blade holder. The cutting blade holder encloses a center hole, so that the rotating cutting apparatus can be mounted to a drive shaft of machinery or secured to a cup that can be mounted to the drive shaft of machinery and driven by the machinery. The cutting blade holder can be made of a less expensive material, with only the cutting blade being made of higher-grade materials that maintains its cutting edge well. Additionally, in some arrangements of the present invention, the cutting blade may be sharpened on two sides so that the rotating cutting apparatus can be used for longer periods of time.||10-08-2009|
