Abstract
A 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. In the method, the embossed pattern is formed from a number of flute portions oriented at an angle to each other and an intersection of these, the intersection and all the flute portions extending from it to a distance from the intersection being produced in a single embossing operation. In addition, 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 mainly produced as a result of the sheet being stretched in the area of the embossed pattern, and the separately pressed embossed patterns are joined together in the areas of the flute portions.
