An assembly () for a tire comprises a first structure (), a second structure () and bearing cord elements. The assembly comprises a gimped securing element () comprising a core () around which a gimp yarn () is wound. The core () exhibits an elongation at rupture Aand the gimp yarn () exhibits an elongation at rupture Asuch that: A<A=h/(E+e+e) and A>A=h/(E+e+e) in which h is the conformation height of the assembly, eis the thickness of the first structure (), eis the thickness of the second structure (), and E is the lock length.

Assembly for a tire, tire and associated manufacturing methods

A process is provided for manufacturing a tire assemblage that includes a first woven or knitted fabric including first threadlike elements, a second woven or knitted fabric including second threadlike elements, and a bearing structure including bearing elements connecting the first and second woven or knitted fabric together. The process includes coating each first threadlike element with a layer of a first adhesive composition and coating each second threadlike element with a layer of a second adhesive composition, heat treating each coated first threadlike element and each coated second threadlike element to crosslink the first adhesive composition and the second adhesive composition, and assembling the bearing elements with each heat-treated and coated first and second threadlike element to form part or all of the tire assemblage.

Assembly intended for a tire and including woven or knitted fabric(s) including pre-adhered wire elements

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.
