Abstract

Un tambor de conformación (1) comprende una pluralidad de sectores (5, 7) para definir al menos una superficie de depósito (3, 4, 6), un cuerpo central (2) conectado a la pluralidad de sectores (5, 7) para poner los sectores (5, 7) en rotación, miembros de acoplamiento (17) que operan entre cada sector (5, 7) y el cuerpo central (2), en el que cada miembro de acoplamiento (17) comprende un primer elemento (18) conectado de forma móvil al cuerpo central (2) o al sector (5, 7) y un segundo elemento (19) conectado de forma móvil entre si entre el cuerpo central (2) y el sector (5, 7), en que se configura el primer elemento (18) para enganchar una primera parte (25) del segundo elemento (19) y sujetar radialmente el sector (5, 7) al cuerpo central (2) y desengancharse de la primera parte (25) del segundo elemento (19) y liberar radialmente el sector (5, 7) del cuerpo central (2), en que se configura el segundo elemento (19) para moverse entre una condición en la que una segunda parte (26) del segundo elemento (19) bloquea el primer elemento (18) y una condición en la que la segunda parte (26) está distanciada axialmente del primer elemento (18).
