Abstract: The invention relates to a method and a device for shaping a metallic flat material to give a metallic wave profile, in which the flat material is passed between two meshing tooth systems of two rotating, toothed rolls. For setting a desired profile height, the centre distance between the rolls can be adjusted, and for presetting of a profile cross-section the flank clearance between the meshing tooth systems can be adjusted. The invention furthermore relates to a method and a plant for the continuous manufacture of a composite material from a metallic wave profile shaped with the aid of the above-described method or the above-described device, and at least one further flat material, which is firmly joined to the wave profile to give the composite material.

Abstract: An air-conditioning element includes ducts, through which gaseous or liquid media are passed for cooling or heating. The air-conditioning element is constructed as a solid metal sandwich with a light core of corrugated aluminum and covering layers of smooth aluminum strip. The media guides are formed between the corrugated aluminum and the covering layers, and the media guides are connected with one another by way of the ducts. A method for the production of the air-conditioning element includes the steps of joining together at a joint a stack of two covering layers and a core of corrugated aluminum, which is disposed between the covering layers, by hot rolling, adhesives, lacquers or other adhesion promoters that have been previously brought into the regions of the joint; and after the stack has cooled, milling a duct in a perpendicular direction to the course of the corrugations, and then closing off the open sections of the duct by a metal strip.
