Abstract: First line element made of, e.g., wire and second line elements made of, e.g., wire are disposed so that they cross each other and they are welded together at crossing points to form a net. The net is pressed to form an undulating net. An undulating net of a first layer and an undulating net of a second layer are laid one upon the other in such a manner that crossing points of the undulating net of the first layer alternately come into contact with and are separated from crossing points of the undulating net of the second layer. The crossing points which are in contact with each other are welded together by a welding machine. Subsequently, undulating nets of a third to n-th layers are similarly processed to form a three-dimensional net-like structure.
