Abstract

Un procédé de fabrication de pneumatiques comprenant la fabrication d’un premier pneumatique et la fabrication d’un second pneumatique de dimensions différentes, où les tringles (8) sont mises en place avec une même distance entre-tringles, et au cours de l’étape de conformation, lorsque l’expansion radiale de la portion centrale de la nappe carcasse (4) atteint un diamètre d’intervention strictement inférieur au diamètre de constitution, un organe de triangulation (10) est mis en contact avec la nappe carcasse (4) afin de modifier l’orientation des renforts carcasse (6) pendant une suite de la conformation, ledit organe de triangulation (10) étant pourvu de renforts (12) parallèles formant un angle (β) non nul avec la direction circonférentielle et la direction initiale des renforts de la nappe carcasse, le diamètre d’intervention et/ou l’organe de triangulation étant différent lors de la fabrication du premier pneumatique et lors de la fabrication du deuxième pneumatique.
