A method of manufacturing at least one flange (1a, 1b) by first rotating a tubular element (30) and two sheet elements (10, 20) with respect to one another until a radially enlarged portion (11) and adjacent hub section (21a,b) have been formed on the tubular element. The sheet element is impregnated by a thermosetting resin. When the resin has cured, the radially enlarged portion (11) is cut along a cut line (S), thereby also dividing the tubular element (30) in two parts (30a, 30b) and generating at least a first flange (1a) having a first flange section (11a) and a first hub section (21a). Optionally, a second flange (1b) having a second flange section (11b) and a second hub section (21b), is generated. In a preferred embodiment, the cut line (S) is arranged in the middle of the radially enlarged portion (11), whereby two similar flanges (1a, 1b) are generated. |
