Abstract

La presente invención se refiere a un aparato y a un proceso para la fabricación de neumáticos para ruedas de vehículos, en el que se incluye colocar los laterales (11) en lados opuesto de una funda de carcasa (12) colocada en un tambor de conformación (13). La colocación de los flancos (11) comprende: colocar cada flanco (11) como un aro alrededor de las palancas de aplicación (24) del respectivo soporte (18), creando un apéndice axial (35) del flanco (11) que sobresale axialmente más allá de los extremos libres (25) de las respectivas palancas de aplicación (241); abriendo de manera radial los extremos libres (25) de las palancas de aplicación (24) de cada soporte (18) para así provocar que cada flanco (11) se expanda radialmente, en donde el apéndice axial (35) se mantiene radialmente más contraído con respecto de la parte restante del flanco (11) y converge hacia el eje de rotación central (X) del tambor de rotación (13); acercando de forma axial los extremos libres (25) de las palancas de aplicación (24) de cada soporte (18) al respectivo medio tambor (17) hasta acoplarse el apéndice axial (35) con la funda de carcas (12); abriendo aún más y de manera radial los extremos libres (25) de las palancas de aplicación (24) de cada soporte (18) hasta darle la vuelta al flanco (11) y adherirse al costado de la funda de carcasa (12).
