Abstract:
1. A process for production of a composite element, comprising: at least one outer layer a); rigid isocyanate-based foam b) adhered to a surface of the outer layer, and an adhesion promoter c) between the surface of the outer layer a) and the rigid isocyanate-based foam b), wherein the process comprises: continuously moving the outer layer a); and successively applying the adhesion promoter c) and a starting material for the rigid isocyanate-based foam b) to the surface of the continuously moving outer layer; wherein; the adhesion promoter c) is applied to the surface of the continuously moving outer layer from a rotating plate installed horizontally or with a deviation of up to 15° from horizontal or parallel to the surface of the outer layer, and the rotating plate comprises an edge region which is angled-off or rounded-off upward.
