Abstract
Pneumatique (1) comprenant un sommet (2) comportant une armature de ceinture ayant une largeur axiale W, une bande de roulement (5) en matériau élastomérique, la bande de roulement comprenant une pluralité de blocs de sculpture (50), deux blocs de sculpture axialement adjacents étant séparés par une rainure (7) s'étendant au moins en partie circonférentiellement, une couche de rigidification constituée d'éléments filaires de renfort rigides en compression, lesdits éléments filaires de renfort étant orientés selon une direction moyenne formant un angle compris entre 50° et 90° avec la direction circonférentielle C, dans lequel les éléments filaires de renfort sont fractionnés en se déplaçant le long de leur direction moyenne, formant des fragments avec recouvrement d'amplitude « R » entre fragments adjacents circonférentiellement et dans lequel les éléments filaires de renfort ont une dimension minimale de 0,15 mm dans le plus petit axe de leur section.
