Abstract (en)
[origin: FR2774625A1] 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.
