Abstract

See full text

A method for manufacturing a bonded reinforcing textile filamentary element (48) comprising a core and a layer of strands is disclosed. The textile filamentary element in the natural state is assembled. A textile filamentary element in the natural state or pre-bonded textile filamentary element is obtained. The filamentary element in the natural state or pre-bonded filamentary element is coated with an external layer of at least one heat-crosslinkable adhesive composition. The filamentary element in the natural state or pre-bonded filamentary element that is coated with the external layer is thermally treated so as to crosslink the adhesive composition in order to obtain the bonded filamentary element (48). The steps of coating with and of thermally treating the external layer of the filamentary element in the natural state or pre-bonded filamentary element are carried out such that, for an elongation equal to 30% of the elongation at break of the filamentary element in the natural state, the tangent modulus of the bonded reinforcing textile filamentary element (48) is increased compared with the tangent modulus of the filamentary element in the natural state.
