    摘要: An extrusion die has a distributing tool; a profiling nozzle; and at least three melt-flow ducts; a first melt-flow duct is routed around a second melt-flow duct or the distributing tool using a branch and is merged again downstream from the branch; and a third melt-flow duct opens into the second melt-flow duct. The extrusion die is suitable for extrusion of a hollow-chamber profiled panel of a thermoplastic plastic with a layered structure which comprises a top and bottom layer of a first plastic melt; and an intermediate layer of a second plastic melt disposed in an interior of a hollow chamber profile. The first plastic melt is allocated to the first melt-flow duct and to the second melt-flow duct and the second plastic melt is allocated to the third melt-flow duct. During the extrusion the second plastic melt is deposited onto the first plastic melt upstream from or in the region of the branch, and a distribution of the deposited second plastic melt is regulated using the distributing tool. The second melt-flow duct conveying the first plastic melt and the deposited second plastic melt is then merged with the first melt-flow duct in the profiling nozzle, whereupon the first plastic melt from the first melt-flow duct is deposited on the second plastic melt from the second melt flow duct, to sandwich the second plastic melt between two layers of the first plastic melt; and the united plastic melts are shaped to the hollow-chamber profiled panel during ejection from the profiling nozzle.
