Screw for double-shaft extruding device and double-shaft extruding device |
摘要 |
A screw for a double-shaft extruding device having a shaft and a spiral flight provided at an outer periphery of the shaft. A height of the flight from an axis of the shaft is substantially constant. An angle of torsion of a spiral of the flight becomes smaller toward a shaft distal end. A cross-sectional area of extrusion formed by the shaft and the flight continuously increases from the shaft distal end to a shaft proximal end. Material can be smoothly discharged and completely extruded.
