Abstract
A mixing extruder with an extruder worm for processing rubber and synthetic materials, which has three regions following each other in its feeding direction. The first one of these regions represents a mixing chamber which can be closed at intervals at all sides. The second region is formed by a storage zone for securing a smooth change-over from discontinuously feeding the extruder to continuously feeding the extruder, and the third region is designed as an ejection zone for feeding material in the extruder to the discharge opening thereof.
