Abstract (en)
[origin: EP0448520A1] In the production of casings by means of surface-treated structural shapes (1), especially of the type in aluminum alloys or equivalent, in order to avoid the presence of sharp edges at the casing corners, a cut (1F) is operated for removing the end of flanges projecting from the structural shapes (1) converging into said corners; and rounded-off angle elements (7) are used, which are solid to square brackets (5) for the mutual centering of said sections, so that said angle elements (7) are positioned into the space defined by said cuts (1F) to complete the casing with rounded-off corners. <IMAGE>
