    摘要： A high-quality cellulose acylate film and saturated norbornene resin film which are produced by a melt film formation method and can be inhibited from having steak failures. Also provided is a process for producing the cellulose acylate film or the saturated norbornene resin film. The process, which is for producing a cellulose acylate film (12) or a saturated norbornene resin film, comprises melting a cellulose acylate resin or saturated norbornene resin with an extruder (22), feeding the molten resin to a die (24) through a piping (23), and ejecting the melt in a sheet form from the die (24) onto a cooled support (26) which is running or rotating to thereby cool and solidify the sheet. Thus, a cellulose acylate film (12) or saturated norbornene resin film is formed. In the process, a static mixer (27) is disposed in the piping (23) and the molten resin flowing in the piping (23) is statically stirred.

    摘要： A screw element for use as a kneading element in a plasticizing unit includes at least two kneading units which can be arranged on a common axis, for example a screw shaft. The kneading units have a geometry which is designed for attaining particularly good plasticization and reduced mechanical stress in such a way that the geometry of at least two successively arranged kneading units differs.

    摘要： An extruder screw comprises a core extending longitudinally from a feed end to a discharge end thereof. The core has a helical primary thread formed thereon. At least one discontinuity is fog lied in the primary thread to divide the primary thread into a plurality of primary thread portions spaced apart from each other in a longitudinal direction of the core. The at least one discontinuity formed in the primary thread may be formed adjacent a downstream end of a compression section of the screw or spanning a transition from the compression section to a section of the screw disposed downstream of the compression section. The discontinuity in the primary thread militates against the problem of solids wedging by allowing any solid materials being processed by the extruder screw to expand and break apart prior to the core reaching a maximum outer diameter.

    摘要： An extrusion apparatus including a mixing chamber comprising two intersecting housing bores and an inlet positioned to receive material into the mixing chamber. Two screw shafts are supported for rotation about respective generally parallel axes and include respective screw sections positioned for co-wiping intermeshing rotation within the respective housing bores of the mixing chamber. The apparatus supports screw shaft rotational speeds greater than approximately 800 rpm and includes screw shaft conveying portions that are rotatably cantilevered for self-journaled support within respective separate conveying chambers arranged generally parallel to one another downstream of the mixing chamber.
