摘要： The invention relates to a measuring nozzle for determining the extensional viscosity of polymer melts during their processing, comprising a flow channel which has a rectangular cross-section and which has a transitional section (3) between an inlet section (1) and an outlet section (2) with respective constant cross-section, which transitional section tapers hyperbolically in the flow direction (8) between two mutually opposite channel walls (6 and 7). In order to provide advantageous measuring conditions it is proposed that the transitional section (3) comprises an inlet-side zone (4) in which the mutual distance of the two channel walls (7) between the two hyperbolic channel walls (6) decreases continuously in the direction of flow (8), and an outlet-side zone (5) which adjoins the inlet-side zone and in which two of the channel walls (6, 7) disposed opposite one another in pairs extend parallel to one another, while the two channel walls (7) arranged therebetween converge hyperbolically in the flow direction (8).

摘要： The present invention is directed to a materials extrusion device including a screw extruder with a plunger feeder. It includes a screw extruder having a main housing, a materials advancing screw, a screw drive mechanism, a feed port for inputting materials to be extruded and an extrusion outlet port. It also includes a plunger feeder having an elongated, upwardly biased (non-horizontal) plunger housing, e.g., a cylinder, with a plunger. A plunger drive mechanism is connected to the plunger to move the plunger upwardly and downwardly within the plunger housing, and there is a feed outlet at an upper end of the plunger housing, the feed outlet being connected to the screw extruder feed port.
