further wherein each amongst the first machine, the second machine and the third machine is configured to respectively sweep a first angular sector of deflection, a second angular sector of deflection and a third angular sector of deflection, said sectors being different from each other.

2. The system according to claim 1 , wherein the base axis is coincident with the axis of rotation, with respect to the common base, of the throwing unit of the second machine.

3. The system according to claim 1 , comprising a base actuator, configured to drive the common base in rotation relative to the stand.

4. The system according to claim 1 , comprising a rolling device interposed between an upper face of the stand and a lower face of the common base.

5. The system according to claim 4 , wherein the rolling device includes at least one rolling set comprising on the one hand a rolling track with a circle arc shaped profile centred on the base axis and arranged on one amongst the upper face of the stand and the lower face of the common base, and, on the other hand, at least one roller rotatably mounted on the other one amongst the upper face of the stand and the lower face of the common base and configured to move along the rolling track.

6. The system according to claim 5 , wherein the rolling device includes several rolling sets at least some of which have rolling tracks having different spacings with respect to the base axis.

7. The system according to claim 6 , wherein the rolling device comprises four rolling sets arranged in pairs on either side of the axis of rotation, relative to the common base, respectively of each amongst the first machine and the second machine.

8. The system according to claim 7 , wherein each pair of rolling sets is arranged opposite a different one amongst the throwing unit of the first machine and the throwing unit of the third machine.

9. The system according to claim 6 , wherein the rolling device includes, at least one rolling set arranged opposite the throwing unit of the second machine.

10. The system according to claim 9 , wherein the rolling set arranged opposite the throwing unit of the second machine includes a circle-like shaped rolling track.

11. The system according to claim 1 , wherein each amongst the first machine, the second machine and the third machine includes a system for setting the angular sector of deflection allowing selectively reducing the angular sector of deflection to one amongst the first angular sector, the second angular sector and the third angular sector.

12. A facility for sport shooting comprising a target throwing system for sport shooting comprising, successively along a direction of alignment, a first target throwing machine, a second target throwing machine, and a third target throwing machine, each of the first machine, the second machine and the third machine comprising:

a throwing unit movable in rotation relative to a base,

a throwing arm movable in rotation relative to the throwing unit,

wherein the base is a base common to the first target throwing machine, the second target throwing machine and the third target throwing machine, and in that it includes a stand on which the common base is movable in rotation along a base axis and a plurality of shooting lanes arranged successively along a circle arc centred on the base axis.

13. The facility according to claim 12 , wherein the system is configured to move the common base in rotation relative to the stand to alternately place the common base in one amongst a plurality of angular positions, each position corresponding to a situation in which the direction of alignment is perpendicular to a line passing through the base axis and the centre of one of the shooting lanes.

14. A method for controlling a target throwing system according to claim 1 in a facility for sport shooting comprising the target throwing system and a plurality of shooting lanes arranged successively along a circle arc centred on the base axis and configured to move the common base in rotation relative to the stand to alternately place the common base in one amongst a plurality of angular positions, each position corresponding to a situation in which the direction of alignment is perpendicular to a line passing through the base axis and the centre of one of the shooting lanes, the method comprising:

placing the common base with respect to the stand in an angular position of the plurality of angular positions,

executing at least one projection of at least one target,

moving the common base in rotation relative to the stand up to another angular position of the plurality of angular positions,

executing again at least one projection of at least one target.

15. The method according to claim 14 , wherein the placement is done in an angular position corresponding to a shooting lane located at a first end of the circle arc and wherein the rotational movement and the new execution are done successively up to a shooting lane located at a second end of the circle arc.
