  • Patent number: 11148379
    Abstract: 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.

  • Patent number: 10543624
    Abstract: A reinforcing element, having a cross section with a flattened overall shape and extending in a main direction and comprising at least one lateral edge made of a polymeric composition comprising a thermoplastic polymer, the lateral edge extending in a general direction substantially parallel to the main direction is treated by heating at least a part of the lateral edge, during which at least a part of the lateral edge is subjected to a plasma flow so as to raise the temperature of the part of the lateral edge above the melting point of the thermoplastic polymer.

  • Patent number: 10377180
    Abstract: The reinforcing element (34) has a cross-section with a flattened overall shape having an aspect ratio greater than or equal to 5 and extending in a main direction (Z1). It comprises a lateral edge (46) made of a polymeric composition comprising a thermoplastic polymer, the lateral edge (46) extending in a general direction substantially parallel to the main direction. The reinforcing element (34) is such that R=(Uc?U1)/Uc>11%, where Uc is the average value of the microhardness of the reinforcing element (34) measured in its central part, and U1 is the average value of the microhardness of the reinforcing element (34) measured at its lateral edge (36). The lateral edge (46) does not have any ridges.

  • Patent number: 6384164
    Abstract: The present invention provides a process for preparing a branched diene elastomer having a high proporation of starred chains comprising anionically polymerizing at least one conjugated diene monomer having 4 to 12 carbons in a polymerization medium comprising a hydrocarbon solvent, such as cyclohexane, and an organometallic initiator, such as n-butyllithium, wherein tris-(2,4-di-tert-butylphenyl)phosphite is added to the polymerization medium as a starring agent during or at the end of polymerization in an amount such that the molar ratio of the starring agent to the initiator is between 0.1 and 1.5, preferably between 0.2 and 0.5. The process produces a branched diene elastomer having a high proportion of starred chains. The elastomer can be a homopolymer, such as polybutadiene or polyisoprene or a copolymer, such as polystyrene/polybutadiene.
