A method for producing thermoplastic plastic foam panels (30) especially extruded polystyrene panels, comprises the steps of feeding foamable plastic material for forming a plastic melt to an extruder (11) and generating a plastic melt therein, and to a nozzle (12) which is positioned downstream from the extruder (11) directing the plastic melt into separate flow channels (16, 17) inside the nozzle (12) to form individual strands, expanding the individual strands to form strands (20a, 20b) of foamed plastic material at the outlet (32) of the nozzle (12), combining, preferably under pressure, the co-extruded strands (20a, 20b) of foamed plastic material at their main surfaces (50) to form a joined strand (22) of foamed plastic material; and cutting the joined strand (22) of foamed plastic material into pieces of defined length to form the panels (30). Further, the invention relates to a device for carrying out the method and a panel as produced by such method and device, and the use of such panel for insulation purposes. |
