METHOD AND APPARATUS FOR PREPARING AN EXTRUDABLE PRODUCT, AND AN EXTRUDED PRODUCT

摘要

The invention relates to a method and an apparatus for preparing an extrudable product, and an extruded product. An extruder according to the invention comprises at least two annular feed gaps (4) between which there is a stator (3), and a rotatable rotor (1) is provided outside the outermost feed gap (4). Inside the stator (3) there is at least one rotatable rotor (2). The product to be extruded can thus be provided with radial orientation without a separate orientation unit. By supplying continuous fibres (20) for example through the stator (3) it is possible to prepare a very strong product that is radially oriented and that comprises axial continuous fibres (20) as reinforcement.
