    摘要： An impregnation section of a die (150) and a method for impregnating at least one fiber roving with a polymer resin are disclosed. The impregnation section includes an impregnation zone (250) configured to impregnate the roving with the resin. The impregnation zone (250) includes a plurality of contact surfaces (252). The impregnation section further includes a device (300) positioned upstream of the impregnation zone (250) in a run direction of the roving. The device (300) is configured to reduce tension in the roving. The method includes tensioning a fiber roving, reducing the tension in the roving, coating the roving with a polymer resin, and traversing the coated roving through an impregnation zone (250) to impregnate the roving with the resin.

    摘要： Prepare an extruded filled polymer composite having a highly disperse and uniformly distributed filler by extruding a filled polymer composite through a die with a Flow Restriction Zone, a Flow Redistribution Zone and a Land Zone. The Flow Restriction Zone is proximate to the extruder and increases polymer melt backpressure in the extruder sufficient to induce high dispersion of the filler but not enough to cause undesirable degradation of the polymer melt components.

    摘要： The present invention is directed to a method and apparatus for using a spiral flow assembly in a polymer extrusion process to make small diameter tubing for such items as wires, cables, and tubing. The invention comprises a mandrel inside of a housing, the mandrel having spiral grooves located on its external surface. A polymer melt is introduced into the housing through an ingress port and flows into and through the spiral grooves on the outside surface of the mandrel, in what is called nullgroove flownull or nullchannel flow.null As the polymer melt flows through the grooves or channels, the housing and mandrel begin to separate by either having the housing taper outwardly, becoming gradually larger in diameter along the axial distance of the mandrel or having the mandrel begin to taper inwardly, becoming gradually smaller in diameter along the axial distance of the mandrel. This allows the polymer, which was restricted to nullchannel flow,null to leak over the top of the walls that separate adjacent grooves, in what is called nullleakage flow.null

    摘要： An extrusion head for extruding a tube-shaped strand from at least one thermoplastic melt for producing blown films, containing an internal member and an external member, between which an annular space is formed. The external member has at least one extrusion module with two extrusion members, which are arranged on top of each other. A separating gap, which terminates in the annular space, is formed between the extrusion members of each one of the extrusion modules. A channel system for distributing the plastic melt into the annular space is formed in each extrusion module. The channel system includes an inlet area, a branching area and a spiral area, each of which is located on a separate level, wherein the level of the inlet area is arranged between the level of the branching area and the level of the spiral area, and a group of first connecting channels leads from the inlet area into the branching area, and a group of second connecting channels leads from the branching area to the spiral area.
