    Abstract: An extruder is disclosed, and more particularly, to an integrated single screw extruder and a twin screw extruder for mixing, compounding, kneading and/or extruding of materials. The integrated extruder includes a first barrel assembly and a second barrel assembly. The integrated extruder further includes a first screw having a first threaded portion and a second threaded portion. The first threaded portion is housed within the first barrel assembly and is configured to provide upstream material processing. The second threaded portion is housed within the second barrel assembly and is configured to provide downstream material processing. The integrated extruder further includes a second screw having a non-threaded shaft portion and a threaded portion. The threaded portion of the second screw is housed within the second barrel assembly and is configured to provide the downstream material processing with the second threaded portion of the first screw.

    Abstract: An apparatus and method for extruding a multilayered article employs a shearing rod connected to the end of an extruder screw. The shearing rod is rotated along with the extruder screw and shears the polymer materials being advanced along an annular space between the shearing rod and the inner surface of a bore in a housing. A first melt stream of polymer material is advanced by the extruder screw into the annular space. A second melt stream of polymer material is fed (e.g., from a second extruder) through a passage in the housing into the annular space to join with the first melt stream therein. The rotation of the shearing rod shears the melt streams and swirls them together to produce a multiplicity of layers of the polymer materials.
