Patent ID: 8507827

Claim:
Manufacturing method for a metal profile having a T-shaped cross-section in a direction substantially orthogonal to a length direction of the profile, said metal profile including a first non-plane metal part forming a lower wing of the T-shaped cross section and a second non-plane metal part forming an upper wing of the T-shaped cross-section, said first and second non-plane metal parts being non-aligned and forming, one relative to the other, an angle evolutionary according to the length direction of said metal profile, wherein said method comprises the steps of: defining a substantially flat outline of the first non-plane metal part and a substantially flat outline of the second non-plane metal part; cutting out in at least one flat metal plate a first flat metal element following the flat outline of the first non-plane metal part and a second flat metal element following the flat outline of the second non-plane metal part, a longitudinal edge of the first metal element being beveled according to said evolutionary angle; forming the first flat metal element according to the non-plane shape of the first non-plane metal part and the second flat metal element according to the non-plan shape of the second non-plane metal part; and coupling the longitudinal edge of said first metal element to a face of said second metal element to thereby form said metal profile having a substantially T-shaped cross section.
