摘要： 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.

摘要： A cord (50) comprises a single layer (52) of helically wound metal filamentary elements (54). The metal filamentary elements define an internal enclosure (58) of the cord of diameter Dv. Each metal filamentary element (54) has a diameter Df and a helix radius of curvature Rf. With Dv, Df and Rf being expressed in millimetres, the cord satisfies the following relationships: 9≤Rf/Df≤30 and 1.30≤Dv/Df≤2.10.

摘要： A method for manufacturing (S) a subassembly (3) for a tire (4) comprising the following substeps: providing an assembly comprising a supporting structure (14) comprising supporting filamentary elements linking a first structure (10) of filamentary elements and a second structure (12) of filamentary elements, aligning (S1) the first structure (10) and the second structure (12), securely fixing (S4) the first structure (10) onto the second structure (12) using a securing element (18), and cutting (S5) the assembly (1) along the securing element (18) so as to separate said securing element (18) from the rest of the assembly (1) and to obtain at least one subassembly (3) without securing element (18).

摘要： The assembly (24) comprises: a woven first fabric (26) comprising filamentary warp elements (64) comprising first and second filamentary members, a woven second fabric (28), a bearing structure (30) comprising filamentary bearing elements (32) connecting the woven first and second fabrics together. For a length at rest L of the woven first fabric (26): for any elongation of the woven first fabric (26) less than or equal to (2π×H)/L, the first filamentary member has a non-zero elongation and is not broken; there is an elongation of the woven first fabric (26), less than or equal to (2π×H)/L, and beyond which the second filamentary member is broken, in which H0×K≤H where H0 is the distance between the woven first and second fabrics (26, 28) when each filamentary bearing portion (74) is at rest, and K=0.50.

摘要： The method for producing a wire element by interlacing at least a first strand and a second strand, during which strand tension control is effected by includes defining an assembly tension set point representative of a state of longitudinal tension to be obtained in the first strand when said first strand reaches the assembly point. The method also includes measuring the actual assembly tension applied in the first strand, said measurement being taken at a first tension measurement point located along the first strand and upstream of the assembly point. The method proceeds with operating a tension regulating member such as a capstan, which acts on the first strand upstream of the assembly point such as to cause the actual assembly tension within said first strand to converge automatically towards the assembly tension set point.
