Abstract: The assembly (24) comprises: a first structure (10) extending in a first overall direction (G1), a second structure (12), and a bearing structure (30) comprising filamentary bearing elements (32) comprising at least one filamentary bearing portion (74) extending between the first structure (10) and the second structure (12), the first structure (10) being arranged such that, for a length at rest L of the first structure (10) in the first overall direction (G1), the elongation at maximum force Art of the first structure in the first overall direction (G1) satisfies: Art≤(2π×H)/L, in which H0×K≤H where H0 is the mean straight-line distance between an internal face (42) of the first structure (10) and an internal face (46) of the second structure (12) when each filamentary bearing portion (74) is at rest, and K=0.50.

Abstract: A tire assembly includes an assemblage formed of first and second impregnated woven or knitted structures, a bearing structure, and at least one sacrificial holder. The first impregnated woven or knitted structure includes a first woven or knitted fabric and a first layer of a first polymeric composition. The second impregnated woven or knitted structure includes a second woven or knitted fabric and a second layer of a second polymeric composition. The bearing structure includes bearing elements connecting the first and second woven or knitted fabrics together. Each sacrificial holder is structured to hold temporarily the first and second impregnated structures in contact with each other, connecting the first and second woven or knitted fabrics together. When the first and second impregnated woven or knitted structures are separated from each other, each sacrificial holder breaks before any breakage of the bearing elements.

Abstract: An assembly (1) for a tire comprises a first structure (10), a second structure (12) and bearing cord elements. The assembly comprises a gimped securing element (18) comprising a core (18a) around which a gimp yarn (18b) is wound. The core (18a) exhibits an elongation at rupture Arupture_core and the gimp yarn (18b) exhibits an elongation at rupture Arupture_gimp such that: Arupture_core A1=h/(E+e1+e2) in which h is the conformation height of the assembly, e1 is the thickness of the first structure (10), e2 is the thickness of the second structure (12), and E is the lock length.

Abstract: 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).

Abstract: 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.
