    摘要: The present invention provides a molding machine crosshead which uses one additional resin extruder and one base resin extruder that are connected to one annular flow channel of a crosshead unit at mutually different angular positions and which is configured to form a parison by adding an additional layer constituted by an additional resin from the additional resin extruder to a base layer constituted by a base resin supplied from the base resin extruder into the annular flow channel, the additional resin being a material different from the base resin, wherein the additional resin is formed in a linear shape along the longitudinal direction of the parison as part of the parison.

    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.
