<p>A method for the production of lightweight structural elements from hollow spheres involves arranging the spheres correctly in layers with the aid of a feeder system and fixing the spheres together by the selective heating of individual spheres and/or groups of spheres. A method for the production of lightweight constructional elements (06, 18, 23, 28) (I) from hollow spheres (01, 29), the supporting shells of which rest upon and are fixed to one another in contact zones. This involves passing the spheres through a feeder (02, 12) corresponding to the required geometry of (I) and arranged them correctly in layers, while selectively heating individual spheres and/or groups of spheres in a fixing step (during or after the arrangement step) so that those spheres are fixed to other spheres, preferably spheres which are already fixed.</p> |
