摘要： The invention relates to a tyre including at least two working layers (41, 43) and at least one layer of reinforcing elements (42). According to the invention, the layer of circumferential reinforcing elements (42) is formed by at least one central part (422) and two axially outer parts (421). The penetration rate of the circumferential reinforcing elements of the central part (422) by the associated rubber mixture coating is less than the penetration rate of the circumferential reinforcing elements of the axially outer parts (421) by the associated rubber mixture coating.

摘要： The invention relates to a tyre comprising a crown reinforcement formed of at least two working crown layers, of at least one layer of circumferential reinforcing elements positioned radially between two working crown layers, the working crown layers adjacent to the layer of circumferential reinforcing elements lying on each side of the equatorial plane and in the axial continuation of the layer of circumferential reinforcing elements coupled across an axial width in order subsequently to be uncoupled. According to the invention, a first additional layer of polymer compound of a width at least equal to the width l of the coupling zone and of a maximum thickness less than twice the thickness of the layer of circumferential reinforcing elements is positioned radially under the radially adjacent working crown layer and on the inside of the layer of circumferential reinforcing elements and is at least partially radially superposed on the region at which the working crown layers are coupled.

摘要： The invention relates to a three-layer metal cord of L+M+N construction, which can be used to reinforce a tyre carcass reinforcement. The inventive cable comprises: an inner layer C1 with L wires having a diameter d1, L varying between 1 and 4; an intermediate layer C2 which surrounds the inner layer, with M wires having a diameter d2, which are helically wound together with a pitch p2, M varying between 3 and 12; and an outer layer C3, which surrounds the intermediate layer C2, with N wires having a diameter d3, which are helically wound together with a pitch p3, N varying between 8 and 20. The cord is characterised in that a sheath, which is made from a crosslinkable or crosslinked rubber composition based on at least one diene elastomer, covers at least the aforementioned intermediate layer C2. The invention also relates to the plastic and/or rubber semifinished products or articles reinforced with one such multilayer cord, such as tyres that are intended for industrial vehicles and, more specifically, heavy vehicle tyres and the carcass bracing plies thereof.
