Abstract (en)
A method for producing profiles, comprising a step of profiling a sheet metal strip to obtain a T profile, characterised in that a plurality of punchings are effected on the web of the T profile with first punches (6) to form pairs of parallel incisions, said profile then being subjected to a further punching step with second punches (8) faced by dies, said first and second punches having substantially trapezoidal longitudinal section, said second punches having their major side, of length L', less than the length L of the major side of the first punches, and having the surface of their cutting tooth outwardly convex.
