    摘要: A tool for extruding a pipe-shaped melt strand of thermoplastic material, having a ring-shaped outlet nozzle and at least one melt conduit leading from an associated inlet opening to the outlet nozzle, which extends concentrically with respect to the center axis of the tool and into whose peripheral wall spirally turning helices are cut and form a helical manifold extending in the outlet direction of the melt strand. The helices are cut into the inner peripheral wall and into the outer peripheral wall of the at least one melt conduit.

    摘要: A process and an extruder nozzle for tubular products includes the steps of feeding pressurized material into an extruder nozzle through an inlet, and forcing this material flow through a duct formed between outer and inner nozzle components, and pressing the material flow through an annular aperture at the duct end. Material entering the extruder nozzle is distributed first by feeding into an annular expansion chamber whose cross-section is much greater than the inlet's. When the expansion chamber is completely filled with material whose pressure has become higher than the flow resistance of a homogenizing ring channel having a cross-section narrowed to and connected to the annular expansion chamber then in the homogenizing ring channel the material flow is forced to move across its entering direction, and is homogenized by the relative rotation of surfaces of the homogenizing ring channel. Helical forced movement leads the material to a drawing aperture.

    摘要: A method for producing multilayer films by the blown film method includes of producing a nine-layer film by combining at least two melt streams and at most three melt streams at each of plural combining locations in a blowing head. The coextrusion blowing head includes a base plate and ten concentric rings defining nine melt channels for the nine individual melt streams. At least two of the concentric rings are supporting rings including flanged attachments for respectively receiving at least one other of the rings. The supporting rings are arranged directly on the base plate.

    摘要: A curable sheath fluid and a core fluid are simultaneously introduced from a hydrodynamic nozzle to form a co-flowing extrusion, depositing at least a portion of the co-flowing extrusion on a material bed, and causing relative motion between the hydrodynamic nozzle and the material bed to form an extruded shape. The method comprises curing part or all of the external curable fluid. The method may introduce co-flowing extrusion to pressure to remove the internal core fluid from the external curable fluid, and may receive the core fluid into the fluid drain system. The extruded shapes may form a tube or plurality of tubes in a bundle or porous substrate. The ability to form concentric tubes and complex shapes provides a means forming high strength materials controlled release materials, and self-repair materials.
