Abstract

Una estructura de carcasa (2a) está acoplada a una estructura de corona (7), formada por una o más capas de cinturón (8a, 8b) dispuestas alrededor de un tambor auxiliar (22). Se dispone un tambor de servicio (31), que comprende sectores (35) distribuidos circunferencialmente alrededor de un eje geométrico central (X1) y radialmente móviles, cada uno de los cuales tiene una superficie radialmente exterior (36) que tiene un perfil curvo en un plano radial con respecto al eje geométrico central (X1). Las capas de cinturón (8a, 8b) se transfieren coaxialmente alrededor del tambor de servicio (31) y los sectores (35) se llevan a una condición expandida, con el fin de dar forma a las capas de cinturón (8a, 8b) de acuerdo con un perfil curvo. Entre los sectores (35) y una superficie radialmente interna de las capas de cinturón (8a, 8b), se interpone al menos un inserto generador de interfaz deslizante (37) que facilita un deslizamiento circunferencial de las capas de cinturón (8a, 8b) con respecto a los sectores (35).
