Abstract

Un tambor de conformación consta de sectores consecutivos circunferenciales (24) que se mueven de manera radial entre una condición contraída y una condición expandida en donde los sectores (24) se alejan de forma radial de un eje geométrico (X-X) para poder definir una superficie de empalme externa radial ("S"). Cada sector (24) tiene porciones de acoplamiento opuestas circunferenciales (36a, 36b), cada una cada una consta de proyecciones circunferenciales (37) alternadas con cavidades circunferenciales (39). Las proyecciones (37) de cada sector (24) se unen de manera deslizable en las cavidades respectivas (39) de los sectores adyacentes circunferenciales. De al menos una de las proyecciones (37), se extiende al menos un ala de soporte (42) que tiene un primer lado (42a) y un segundo lado (42b) que son opuestos de manera respectiva. El primer lado (42a) coincide con una porción de la superficie de empalme ("S") y el segundo lado (42b) se sobrepone al menos de manera parcial sobre una de las proyecciones (37) que pertenece a un sector adyacente (24). También se describe un proceso para fabricar neumáticos usando el tambor antes mencionado.
