    摘要: Material is extruded with a device comprising at least two stators (1,2) one within the other and, between them, a rotor (3) in the shape of a convergent cone, the material being extruded from the device by rotating the rotor (3). The rotor (3) comprises openings (9), through which the material is led. The stators (1,2) comprise continuous grooves (8) for conveying the material out of the device. The stator grooves (8) alternately become lower and deeper, said grooves (8) being arranged such that when the groove of the inner stator (1) is low, the point of the groove of the outer stator (2) on the other side of the rotor (3) at a corresponding point is deep and vice versa.
