    Abstract: An inner die of a molding die includes a core shaft, split dies radially arranged along an outer peripheral surface of the core shaft around an axis of the core shaft, which serves as a center, and a cylindrical set ring arranged below the split dies, the core shaft being inserted through the set ring. An annular engaging surface, which is a tapered surface whose diameter is gradually reduced downward, is formed in an inner peripheral side of an upper end portion of the set ring, and lower end portions of the respective split dies are introduced into, and engaged with the engaging surface. The molding die includes a pressing portion that presses downward upper end portions of the respective split dies introduced into the set ring, so as to move the lower end portions of the respective split dies toward the axis along the engaging surface.

    Abstract: An actuating system of sectors of a device (2) for producing an airplane fuselage. Each sector is provided with an actuating system (27) of the screw - nut screw type in which a threaded element (31) is rotated about a rotation axis (32) by a motor (28). The threaded element (31) comprises an internal shaft (33) made of a first material and extending along the rotation axis (32) and an external tubular portion (34) made of a second material, mounted axially on a portion of the shaft and provided externally with a thread. Constraint means (38) are provided between the internal shaft (33) and the tubular portion (34) adapted to prevent angular displacement of the tubular portion (34) with respect to the internal shaft (33) allowing linear sliding of the tubular portion (34) with respect to the internal shaft (33). A thermal stress applied to the threaded element (31) produces the sliding of a free end portion (34a) of the tubular portion (34) with respect to the internal shaft (33) so that an increase in the temperature does not produce an overall elongation of the threaded element (31) maintaining each sector in the expanded lamination position previously defined.
