Abstract: A tower (C) production method is developed with the present invention, comprising a first production stage including the steps of unrolling and bringing into a planar state a sheet metal (B) wound around a coil (A); bending the planar sheet metal (B) at the lateral direction at varying bending radii (d); and winding the bent sheet metal (B?) into a conical coil (A?), as well as a final production stage yielding the tower and including the steps of feeding the sheet metal (B?) unwound from the conical coil (A?) to at least one winding machine (8), and bending and winding the bent sheet metal (B?) in the winding machine around a central bending axis (T) parallel to one surface (B1) thereof so that a defined initial winding radius and the angle between a longer edge (B3) thereof and the axis (T) are kept constant and the longer edge (B3) of the sheet metal is joined over itself.
