Abstract

Pneumatique pour véhicules gros et très gros porteurs circulant hors la route, avec une armature de carcasse radiale et une armature de sommet formée de trois nappes obliques de fils ou câbles parallèles dans chaque nappe, deux de ces nappes étant des nappes à bords non repliés, l'autre nappe étant une nappe dont les bords sont repliés autour d'au moins une des deux précédentes. Selon l'invention, les câbles de l'une des nappes à bords non repliés 311 sont parallèles à ceux de la nappe à bords repliés 310 et croisent ceux de l'autre nappe à bords non repliés 32. Application : pneumatiques pour roues de véhicules.
