The invention concerns a method which consists in heating the part to be folded of the composite section comprising a hollow body (1) and a coating sheet (2) on one surface and an edge zone, with a temperature gradient from one surface (11, 12) to the other; in pressing the hot forming projecting member (4) against the non-coated surface (12) to bring it closer or press it against the coated surface (11); and while maintaining edges in pivoting at least one of the section parts which are on either side of the zone formed by the projecting member to form therein a fold along a line transverse to the surfaces, approximately perpendicular to the sheet (2) limit on the edges. The resulting section is useful for constituting a double glazing bracing frame.
On chauffe la partie à plier du profilé composite comportant un corps (1) creux et une feuille de revêtement (2) sur une paroi et une région des chants, avec un gradient de température d'une paroi (11, 12) à l'autre, on appuie une saillie de formage (4) chaude contre la paroi (12) non revêtue pour la rapprocher de ou l'appuyer contre la paroi (11) revêtue, et en maintenant les chants on pivote au moins l'une des parties du profilé qui sont de part et d'autre de la région formée par la saillie pour y constituer un pli selon une ligne transversale aux parois, au droit approximativement de la limite de la feuille (2) sur les chants. Le profilé est utilisable pour former un cadre d'entretoisement de double vitrage.
