Abstract
A method for making helicopter blade spars in which a tape of reinforced resin is laid up with a continuous circulatory movement along an annular path defined by a lateral surface of a former of a forming mould in such a way as to define an annular body constituted by two ribs of the spar, rigidly connected together and opposite one another; each rib being subsequently separated from the other by cutting the said annular body.
