초록

A double screw extruder includes two conical extruder screws whose screw shafts are arranged at an angle to one another corresponding to the conicity of the extruder screws, and a drive apparatus for driving one of the screw shafts. The other screw shaft is driven from the first screw shaft through a bevel gear drive provided with teeth arranged in herringbone or arrow fashion.
