Abstract

L'invention concerne un dispositif permettant d'améliorer la précision lors de l'enroulement de pièces de confection de pneumatiques. Pour cela, le réglage du diamètre de la surface de tambour extérieure est couplé à deux moyens de déplacement de forme conique (2, 3) disposés dans des directions opposées. Les moyens de déplacement de forme conique (2, 3) sont mobiles dans la direction axiale (9) et, lors de ce mouvement, les différents segments de tambour (11) sont déplacés dans la direction radiale (10), les deux moyens de déplacement de forme conique (2, 3) pouvant recevoir et rediriger sur les segments de tambour (11) des forces agissant dans la direction radiale (10). Les deux moyens de déplacement en forme de cône (2, 3) sont montés de manière sensiblement symétrique par rapport au centre (7) du tambour et se déplacent de manière sensiblement symétrique par rapport au centre (7) du tambour lors du mouvement de déplacement, de sorte que les forces sont reçues de manière uniformément répartie sur les segments de tambour (11) et le fléchissement des différents segments de tambour (11) est empêché ou sensiblement réduit dans la direction radiale (10).
