<p>The invention relates to a method for making a sandwich element, said element having a core layer of a heat insulation material, and a surface layer of a metallic material at least on one side of the core layer, said surface layer providing a facade panel for the sandwich element with a desired embossment made on said facade panel. The method comprises forming on said surface sheet metal a discontinuous embossment in a continuous process, wherein a panel material (5) constituting the surface panel is delivered through a press nip between an embossing roll (1) forming a desired discontinuous embossment and a counter-roll (2) made of an elastic material for producing a desired discontinuous embossment on the panel material. The invention further relates to a press assembly for producing an embossment on the facade surface of a sandwich element.</p> |
