Abstract (en)
[origin: EP0071700A2] The object of the invention is to provide the casing in such a way that prefabrication in the factory in accordance with the various standardised profile girders is possible. The object is solved by several successive process steps, consisting in that a) a fire-proof cover is fixed to a working base by gluing, b) subsequently, the working base together with the covering is profiled such that a layout is produced which cases the profile and c) then, by positive or self-substantial connection, the casing surrounds the metallic profile. The invention is used not only for casing girders, but also for manufacturing structural elements, e.g. in furniture making. <IMAGE>
