WORM SCREW FOR USE IN AN EXTRUDER AND EXTRUDER

摘要

The invention relates to a screw to be used in an extruder, in particular in a single-screw extruder or a multiple screw extruder, and to such an extruder. In the state of the art, extruder screws are often composed of segments which are supported by a spindle and mutually axially braced. To enable transfer of the torque to the segments during use of the screw within the extruder cylinder, there are means for positive engagement between the spindle and the segments. The present invention instead proposes the use of an additional component as a moment bridge directly from segment to segment so as to take load off the spindle.
