- This malfunction can be considered as an accidental blockage of the actuator 35 with the actuation element 36 adopting the second position.
- the machine 1 is configured so that the guiding cam 41, by means of the rotation of the carousel 9 and in the case of accidental blockage of the actuator 35 with the actuation element 36 adopting the second position, exerts a decoupling action on the cam follower 42.

- the filling unit 10 is configured so that the actuation element 36 interacts with a region of the gripper 24 between the rotation axis F and the gripping element 23.

- the two magnets 38 carried by the gripper 24 are arranged at opposite sides of said slot 31 to interact with said the magnet 37 carried by the actuation element 36, so as to define the magnetic coupling.

- the longitudinal axis E of the gripper 24 is in a first orientation and a second orientation distinct from the first orientation with the respective elongated gripper 24 being controlled into respectively the first position and the second position.
- the longitudinal axis E is preferably orthogonal to the respective longitudinal axis C of the filling valve 16 when being, in use, in the first orientation.
