    Abstract: In order to achieve an economical and trouble-free continuous extrusion of plastic hollow profiles having at least one hollow chamber that is filled with foam, the profile tool of an extrusion device is configured in the shape of a pistol. The profile tool comprises a pistol shaft (102) with a melt feed channel (166), connected to the melt discharge opening of the extruder (300) and which opens into a melt radial distributor channel (164) that surrounds the lance guide channel (150). The profile tool is also equipped with a pistol barrel (101) comprising a melt ring channel (162), which extends from the melt radial distributor channel (164) to the profile nozzle (160) and comprising a lance guide channel (150), which extends in a continuous manner from a lance inlet (152) to the profile nozzle (160).
