Abstract:
1. A continuous edge structure being an edge or edge support for a lightweight building element, wherein: the lightweight building element is a planar structure two cover regions and a filling region between the cover regions; the edge structure comprises contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the lightweight building element and further comprises, opposite the contact surfaces, a coupling-in surface for coupling energy into the edge structure; the edge structure is shaped so that at least a portion of the thermoplastic material is liquefied and pressed into the cover regions when energy is coupled into the edge structure while the contact surfaces are pressed against the cover regions; the edge structure comprises at least regions which are formed to run between the cover regions after the pressing the thermoplastic material portions into the cover regions; and, the edge structure is continuously extended to run along an edge of the lightweight building element.
