Abstract
A method of manufacturing at least one flange by first rotating a tubular element and two sheet elements with respect to one another until a radially enlarged portion and adjacent hub section 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 is cut along a cut line, thereby also dividing the tubular element in two parts and generating at least a first flange having a first flange section and a first hub section. Optionally, a second flange having a second flange section and a second hub section, is generated. In a preferred embodiment, the cut line is arranged in the middle of the radially enlarged portion, whereby two similar flanges are generated.
