Abstract

Método para doblar sobre las superficies laterales de una armazón de neumático, conformada en forma tórica, a lo menos las tiras de los flancos y las extremidades de las telas de armazón, predispuestas sobre cada lado de la armazón en forma aproximadamente parabólica, dicha parábola teniendo el eje coincidente con aquel de la armazón, la concavidad vuelta axialmente hacia el exterior respecto a dicha armazón, la zona periférica interna de dicha superficie parabólica estando solidaria con el talón de la armazón, caracterizado por el hecho que consiste en efectuar dicho doblamiento mediante la contemporánea ejecución de las operaciones de dilatación circunferencial, vuelco y rodilladura del flanco de la armazón de dichas extremidades de las telas y dichas tiras de flanco.
