| 20080286599 | Method and Device for Producing Metal Panels with a Pattern - The invention relates to a device and method for producing metal panels. First a metal melt is produced, then a substrate, which has a lower temperature than the metal melt, is brought into contact with it so that some of the metal melt crystallises on the substrate. The substrate is then moved relative to the metal melt so that a metal foil is formed on the substrate. Finally the metal foil is divided into metal panels. According to the invention the substrate comprises grooves which are used to fit partitions between the panels, as well as grooves which are filled with liquid metal. The latter grooves provide a reinforcement for the metal panels. In addition a pattern of recesses and/or elevations can be provided in the substrate so that the same pattern is formed in the metal foil. The pattern may consist, for example, of parallel grooves which ensure that the surface of the foil is enlarged. In the case of solar cells this results in greater efficiency. | 11-20-2008 |

| 20110165430 | Flat product composed of a metal material, in particular a steel material, use of such a flat product and roller and process for producing such flat products - With the invention a metallic flat product can be systematically made available with such a fine, stochastic or quasi-stochastic surface texture that after a typical automotive paint application it is only minimally perceptible, if at all, by the human eye. At the same time, in the case of a surface topography constituted according to the invention, the transition between the peak plateaus and the valleys takes place via steep flanks. In this way, it is achieved that the morphology of the sheet metal surface is practically independent of the actual depth of the valleys. As a result therefore, the morphology of the sheet metal surface of a metallic flat product according to the invention is also independent of the skin-pass rate, which is obtained when the fine metal texture is produced by skin-pass rolling. | 07-07-2011 |
