1. A method of extruding thermocrosslinked materials characterised by that first at least one layer (28a) of thermocrosslinked material is extruded in an extruding press (20) containing at least one wall (22) of mouthpiece, then along with extruding a layer of crosslinked material at least one layer (28b) of thermocrosslinked material is extruded in the extruding press (20) between the thermocrosslinked material and at least one wall (22) of mouthpiece, and then crosslinking of the thermocrosslinked material is stimulated by applying heat.
