Assembly for a tire, tire and associated manufacturing methods

An assembly for a tire comprising:

• a first structure formed by first cord elements, the first structure having a longitudinal edge extending in a first direction which defines a first axis;
• a second structure formed by second cord elements, the second structure comprising a longitudinal edge extending in a second direction which defines a second axis, the first axis and the second axis being parallel;
• a bearing structure comprising bearing cord elements linking the first cord elements of the first structure and the second cord elements of the second structure;
• and
• at least one cord securing element fixed to the first cord elements and to the second cord elements,
• wherein the at least one cord securing element comprises a gimped cord element comprising a core around which a gimp yarn is wound,
• wherein the core of the at least one cord securing element exhibits an elongation at rupture lower than a ratio between a conformation height of the assembly and a sum of a thickness of the first structure, of a thickness of the second structure and of a lock length:
• Arupture_core<h/(E+e1+e2)
• in which:
• Arupture_core is the elongation at rupture of the core,
• h is the conformation height of the assembly, corresponding to a height between opposite faces of the first structure and of the second structure when the bearing cord elements are taut,
• e1 is the thickness of the first structure;
• e2 is the thickness of the second structure, and
• E is the lock length, and
• wherein the gimp yarn of the at least one cord securing element exhibits an elongation at rupture greater than an elongation equal to the ratio between the conformation height of the assembly and the sum of the thickness of the first structure, of the thickness of the second structure and of the lock length:
• Arupture_gimp>h/(E+e1+e2)
• in which:
• Arupture_gimp is the elongation at rupture of the core.
