Abstract
Foil extrusion lines use spiral distributors for producing a melt which is as homogeneous as possible during operation. The spiral distributors are mostly available as cylindrical or conical axial spiral distributors or as radial spiral distributors. The spiral distributors have spiral channels that run in a multiple spiral arrangement so that rather flat horizontal edges are formed precisely in initial sections and vertical edges are formed between the beginning of spiral channels and transition sections of adjacent spiral channels. The melt can easily adhere there. To accelerate the melt in critical areas, the course or the cross-section of the channels or the surface are modified.
