RESERVOIR REDUCING SCREW TIP. |
摘要 |
<p>An extruder for extruding extrudate is provided and includes a generally cylindrical barrel portion having an end face. A screw conveyor is rotatably arranged coaxially within the barrel portion and has a downstream end. The screw conveyor has helical flights that define a first flow path with the barrel for the extrudate. The first flow path has a first cross-sectional area. An adapter is arranged on the end face of the barrel portion and defines an exit portion of the extruder. A screw tip is secured to the downstream end of the screw conveyor and extends into the adapter. The screw tip and the adapter define a second flow path for the extrudate with a second cross-section area being at least as large as the first cross-sectional area.</p> |
