Abstract:
1. Forming method for producing wall and ceiling cladding sheets from sheetmetal, wherein embossed patterns are pressed into a metal sheet so that they cover the entire surface area of the sheet substantially uniformly, wherein a first embossed pattern is formed from four flute portions oriented at right angles to each other and an intersection of the flute portions, the intersection and all the flute portions extending from it to a distance from the intersection being produced in a single embossing operation, the metal sheet is clamped from opposite sides in an area outside the embossed pattern and held in place so that the embossed pattern is produced as a result of the sheet being stretched in the area of the embossed pattern, and separately pressed adjacent embossed patterns are joined together with the first embossed pattern in overlapping areas of the flute portions, and a length of the overlapping flute portions are adjusted to adjust a distance between the first embossed pattern and the adjacent embossed patterns and a distance between the intersections of the flute portions of the first embossed pattern and the adjacent embossed patterns.
