Embodiment Construction

[0042] exist figure 1A device for flattening strip-shaped metal sheets 1 is shown. The metal sheet 1 is preferably a steel sheet, eg having a thickness in the range of 0.1 to 0.5 mm. The plant comprises a rolling stand with temper rolls 2a, 2b defining a rolling gap substantially smaller than the thickness of the strip 1 to be tempered. By flattening, a defined roughness is formed or adjusted on the individual sides of the metal strip 1 . Each of the two temper rolls 2a, 2b has a specific surface structure for this purpose.

[0043] According to the invention, for the levelling of the metal strip 1, levelling rolls 2a, 2b with surface structures of different degrees of roughness are used. For example, the upper temper roll 2a has a relatively flat surface structure, while the lower temper roll 2b has a relatively rough surface structure. this is in figure 1 a and figure 1 Schematically shown in b on an enlarged scale in surface sections of the temper rolls 2a, 2b, repres...

Abstract

The present invention provides a metal-plastic sandwich sheet and a method for the production thereof. The invention relates to a metal-plastic sandwich sheet (18) having metallic outer sheets (1a, 12a) and at least one plastic layer (1b, 12b; 18b) which is arranged between the outer sheets and is bonded integrally to the outer sheets (1a, 12a). In order to improve a sandwich sheet of this type in respect of the further-processing properties thereof, the invention proposes that at least one of the two outer sheets (1a, 12a) is formed from a metal sheet having surfaces (1*, 1**, 12*, 12**) of differing roughnesses, wherein the difference in the roughness averages is at least 0.4 [micro]m, preferably at least 0.5 [micro]m. The invention is based on the concept of manufacturing the outer sheets (1a, 12a) with a differing roughness on the top and bottom side (outer and inner face) thereof, such that it is possible to freely satisfy the respective optimum in respect of the roughness desired by the customer for the outer faces of the sandwich material and also the optimum in respect of the bond between the outer sheet (1a, 12a) and the plastic layer (1b, 12b; 18b). A method for producing such a sandwich sheet (18) is also described and claimed.

Description

technical field [0001] The invention relates to a metal-plastic sandwich panel with metal cover panels and at least one plastic layer arranged between the cover panels and connected to the cover panels in a materially fit manner. Furthermore, the invention relates to a method for producing a sandwich panel of this type. Background technique [0002] Lightweight construction is gaining more and more importance in motor vehicle construction, especially in order to reduce the fuel consumption of motor vehicles or to reduce CO 2 emissions. Known measures for reducing the weight of motor vehicles are the use of aluminum or steel-plastic composite panels in the body structure instead of conventional steel sheets. [0003] The applicant sells the brand as The steel-plastic composite panel consists of two thin steel sheets as covering panels and a core layer made of plastic arranged between them. The cover sheet here has, for example, various thicknesses in the range of 0.2-0.3...
