Device and method for manufacturing foamed sandwich composite material elements

摘要: Coating apparatus, for producing evenly foamed, simultaneously applied foams over a reaction surface, comprises mixing head (9), distribution (10) and at least three outlet lines (12), to the fixed transversely outflow direction rigid frame (13). Independent claims are included for: (1) apparatus sandwich composite elements, comprising (in series) two supply devices upper lower covering layers, revolving belt guiding layer, layer onto coating as described above (for application of foamed core layer), shaping zone device cutting length; (2) method elements using in which one or both components blended together has been previously mixed with inert gas is (specifically air, carbon dioxide noble gas) itself.
