Abstract

L'invention concerne un procédé de fabrication d'un pneu permettant de réaliser une réduction du déséquilibre dynamique et d'améliorer la durabilité. A cet effet, l'invention concerne un pneu avec une saillie au niveau de sa zone de renfort, ledit pneu étant fabriqué selon le procédé suivant. Un caoutchouc de paroi latérale (17) ayant un produit résistance à la traction par allongement à la rupture de 10 000 à 12 000 MPa % après vulcanisation est fixé au côté externe d'un pli de carcasse (12). Un tambour de moulage (1) est actionné de façon à effectuer un agrandissement de diamètre. Ensuite, un pli de ceinture (19) et un caoutchouc de bande de roulement (18) ayant un produit résistance à la traction par allongement à la rupture de 15 000 à 18 000 MPa % après vulcanisation sont fixés au côté externe d'une zone du pli de carcasse (12) correspondant à une partie de sommet, pour obtenir de cette façon un pneu cru (G). Un élément de caoutchouc de bande (21) ayant un produit résistance à la traction par allongement à la rupture de 15 000 à 18 000 MPa % après vulcanisation est fixé à la zone de renfort (B) du pneu cru (G) pour former de cette façon une saillie circulaire (22). Le pneu cru (G) est moulé par vulcanisation à l'aide d'un moule métallique.
