Publication number: 20200207002Abstract: An extrusion die including a die body having a movable die lip, is provided with improved automated control of the exit orifice through which a flowable polymer is extruded. The automated control is provided by lip adjustment assemblies each of which includes a thermally responsive translator and each of which is in engagement with the movable die lip. Beneficially, the lip adjustment assemblies are also in engagement with a support structure located to reduce the effect of flow pressure-induced deflection. Improved automated control of the movable lip and the exit orifice gap provides a web having a prescribed thickness profile without manual intervention being required.Type: ApplicationFiled: December 28, 2018Publication date: July 2, 2020Inventor: Peter F.

Patent number: 9067351Abstract: The present invention provides an extrusion die that includes a manifold transition zone that comprises a varying included angle. The varying included angle provides unparalleled freedom of design to achieve diverse fluid dynamic objectives, such as reduced residence time across the manifold width, reduced transition stagnation, improved streamlining of the mass flowing through the manifold, and reduced differential clamshell deflection across the flow channel width. The manifold may be transformed from one cross-sectional shape to another cross-sectional shape beneficially related to the varying included angle, including change from a generally extended cross-sectional shape to a generally teardrop-shaped cross-section. The manifold may include a first transition zone portion that includes the varying included angle, and a second transition zone portion that includes a constant included angle, and that is particularly beneficial for receiving an internal deckle.Type: GrantFiled: March 29, 2012Date of Patent: June 30, 2015Assignee: CLOEREN INCORPORATEDInventors: Peter F. Cloeren, Giuseppe Negri, Olivier Catherine

Patent number: 6905324Abstract: A method and apparatus for the extrusion of multilayered composite products, is provided. The inventive apparatus includes a coextrusion structure and a partition member. In accordance with the inventive method, the relative orientation of a first shaped flow stream and a second shaped flow stream to one another is changed, and the reoriented shaped streams are melt-laminated to produce a layered composite formed independent of division of a layered precursor stream. The reorientation occurs via a flow sequencer, which may be removably disposed. Beneficially, layered flow streams that differ from one another may be used. The coextrusion structure may advantageously include one or more removably disposed, flow-shaping inserts, and the partition member may be a removably disposed, partition plate.Type: GrantFiled: April 26, 2002Date of Patent: June 14, 2005Assignee: Cloeren IncorporatedInventor: Peter F.
