Abstract: A process for the production of an at least two-layer thermoplastic foam sheet via symmetrical bonding, e.g., by thermal welding, of at least two thinner thermoplastic foam sheets to give the at least two-layer thermoplastic foam sheet. The invention further relates to thermoplastic foam sheets having at least two layers. The number of the layers of the thermoplastic foam sheet derives from the number of thin thermoplastic foam sheets that are thermally welded to one another.

Abstract: The present invention relates to a tool (W) having at least one first inlet opening (E1) and at least one second inlet opening (E2), and also at least one first outlet opening (A1), at least one second outlet opening (A2) and at least one third outlet opening (A3), wherein the second outlet opening (A2) and the third outlet opening (A3) alternate with the first outlet opening (A1). The present invention further relates to a process for producing a fiber/foam composite by extruding through the tool (W) and to the use of the tool (W) for production of a fiber/foam composite by extrusion.
