    (54) Procedures for the elaboration, handling and industrial use of flexible metallic profiles


    (57) Procedures for the elaboration, handling and industrial use of flexible metallic profiles, consisting of the mechanization of wide hoops which are died and adjusted throughout a cold process in order to obtain the T-, M-, angle-shaped profiles, and the like, with the main characteristic of being easily curved in one of their sides, without being necessary to use neither any tool nor heating processes, because the other sides of the profile do not show any resistance, as they are made of planes with grooves which relative shifts, by sliding ones over the others. The handling and use of these profiles need of a manual configuration on patterns, models or plans as designed, and the later rigidity throughout solid junctions which fix the shifted position of the grooved planes, thereby maintaining the requested curve.
