A layer (7) of a reinforcing sheet material is applied by means of an adhesive to the inner surface or face (6a) of said flexible material (6), and a layer of adhesive is applied onto the reinforcing material (7), and a strip of the thus obtained composite material is folded on itself around the core (8).
