In order to rivet a light alloy added reinforcement rib (13) on a shell structure made of composite material (11), an external working head (21) is brought near to the external side of the wall of the shell structure (11), until a predetermined thrust is applied; an internal working head (45) is brought near to the internal side of the wall of the shell structure (11), until the load detector of the external (21) detects a predetermined variation of the thrust applied to the shell structure by the external working head (21); with the external working head (21) a thrust is applied to the external side of the shell structure (11), equal to a predetermined compression force, necessary for drilling. This allows the shell structure (11) be drilled with a cheaper apparatus, since only one of the two drilling robots (38, 45) used is provided with pressure sensors. |
