Abstract
método de fabricação para pneus. um método de fabricação para pneu inclui um processo em que uma cobertura bruta (2) para um pneu é formada, e um processo de vulcanização em que a dita cobertura bruta (2) é inserida dentro de um molde (3) e submetida à moldagem por vulcanização. com a cobertura bruta (2) inserida no molde (3), uma borda de borracha da parede lateral (e), que é uma parte limite entre uma chafer de franja (13) e uma borracha de parede lateral (12) que aparece em uma superfície exterior (2a) da cobertura bruta, é localizada mais para o interior do pneu na direção radial do que um ponto de núcleo interior (p1), que é o ponto de interseção entre a superfície exterior (2a) da cobertura bruta e uma linha axial (l1) que passa através de um núcleo de franja (7) na borda interior do pneu na direção radial. o método de fabricação é caracterizado pelo fato de que uma borda exterior (15bo) de uma parte voltada para cima (15b) de uma borracha de isolamento (15) passa entre uma parte voltada para cima (9b) de uma dobra de carcaça (9a) e a borracha da parede lateral (12), e termina mais adiante para o exterior do pneu na direção radial do que a borda de borracha da parede lateral (e).
