Tire comprising a protective reinforcement
First Claim
1. A tire with radial carcass reinforcement, made up of at least one layer of metal reinforcing elements, the tire comprising:
- a crown reinforcement,a tread radially capping the crown reinforcement, comprising at least two circumferentially continuous cutouts,two beads connected to the tread via two sidewalls,wherein the crown reinforcement comprises at least one axially discontinuous layer consisting of at least two bands axially distant from one another, and each formed of at least one multilayer laminate,wherein the laminate comprises at least one multiaxially stretched thermoplastic polymer film positioned between, and in contact with, two layers of rubber composition, and wherein, in a meridian plane, axial ends of each of the bands are respectively axially on the outside of each of the axially outermost points of one same circumferentially continuous cutout, wherein the axial distance between an axial end of a band and the axially outermost point of the circumferentially continuous cutout axially closest to the end of the band is between 4 and 12 mm;
wherein at least one band is disposed radially beneath at least one circumferentially continuous cutout; and
wherein the thermoplastic polymer is a polyester,the crown reinforcement of the tire comprises at least two multilayer laminates positioned in contact with one another circumferentially to form a circumferentially continuous band, andthe ends of the at least two multilayer laminates in the circumferential direction have a cutout that makes with the circumferential direction an angle substantially equivalent to that of the reinforcing elements of the crown reinforcing layer radially closest to the at least two laminates.

Abstract
The invention relates to a tire with a radial carcass reinforcement comprising a crown reinforcement, itself radially capped with a tread comprising at least two circumferentially continuous cutouts, the said tread being connected to two beads via two sidewalls.
According to the invention, the crown reinforcement comprises at least one axially discontinuous layer consisting of at least two bands each formed of at least one multilayer laminate, the said laminate comprising at least one multiaxially stretched thermoplastic polymer film positioned between and in contact with two layers of rubber composition, and, in a meridian plane, the axial ends of each of the said bands being respectively axially on the outside of each of the axially outermost points of one same circumferentially continuous cutout.
