Method for the manufacture of a burner from a sheet-metal strip by cutting, bending and stamping (deep-drawing) operations by means of a combined tool for cutting and profiling the ends (24) of the burner in the sheet-metal strip (20), producing, in the central portion (33), a profile (35) which includes an edge (34), bending the longitudinal rims (43, 44), stamping the profile (35) and forming gas jets (59) by cracking (tearing) the metal sheet in order finally to press the side walls against each other via their external faces. <IMAGE>
