Abstract

L'invention concerne un procédé et un dispositif servant à la production de pneus verts. Au moins un matériau en forme de bande est amené à au moins un tambour de production de pneus. Deux tambours de production de pneus sont associés entre eux et sont montés pivotants par rapport à un axe de rotation. La production d'un pneu comprend l'introduction, en premier lieu, dans la zone du premier tambour de production de pneu, d'un premier matériau en forme de bande, puis, après exécution d'un mouvement de rotation et d'une interversion des positions des tambourss de production de pneus qui en résulte, l'introduction d'un second matériau en forme de bande,
