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 exhibits an elongation at rupture at least equal to a minimum elongation greater than or equal to 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:
• Amin≥h/(E+e1+e2)
• in which:
• Amin is the minimum elongation of the at least one cord securing element,
• 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.
