Claims7
A method for the production of a fastening element for dry construction elements comprising:
- a sheet metal material having at least one joining section, the sheet metal material being provided with a plurality of depressions in the area of the at least one joining section, the depressions being formed by deformed areas of the sheet metal material, so that the depressions on one side of the sheet metal material form elevations on an opposite side of the sheet metal material, the depressions each being surrounded by sliding surfaces at least partially slanted relative to an imaginary center line of the sheet metal material and being for connectors to be inserted into or through the joining section,
- wherein, in the at least one joining section, the sheet metal material has no surface parallel to the imaginary center line of the sheet metal material, except for the depressions or elevations, the method comprising:
- feeding a flat sheet metal material through a nip formed between a top roller having first teeth and a bottom roller having second teeth, in order to create the depressions and elevations as well as the slanted sliding surfaces.
