<p>A method for producing homogenous material with an extruder, an extruder, and a multilayer plastic pipe. The extruder according to the invention comprises at least two conical stators (1, 2) and at least one rotatable conical rotor (3) placed between the stators. The rotor (3) comprises openings (12) between the delivery point of the material to be extruded and the nozzle of the extruder in the direction of travel of the material, at least a part of the material to be extruded being made to flow through the openings (12). In such a case, the material to be supplied can be mixed very efficiently, whereupon the extruder discharges very homogenous material. The invention also relates to a multilayer plastic pipe.</p> |
