Abstract

Method for the manufacture of homogeneous material by means of an extruder, extruder and multilayer plastic pipe. The extruder according to the invention has at least two conical stators 1, 2 and between them at least one rotor 3 designed to rotate. Between the inlet point for the extruder material and the extruder nozzle in the conveying direction of the material, the rotor 3 has openings 12, through which at least a proportion of the extruder material is designed to flow. In this way the extruder material is mixed particularly efficiently, so that particularly homogeneous material is obtained. The invention also relates to a multilayer plastic pipe. <IMAGE>
