System for marking a cable with a curved marking area

1. Cable marking system comprising:

at least one laser device,

at least one marking area ( 5 ) for marking a portion of cable ( 1 ) by means of said at least one laser device,

at least one cable-driving device ( 2 , 9 , 10 , 11 , 13 , 14 ) configured to cause said cable to pass through in said at least one marking area, and

at least one cable curving device ( 2 , 15 , 17 ) configured to curve said cable in said at least one marking area,

in which said at least one laser device is configured to emit at least one laser beam which, in the marking plane encompassing the surface of said cable, follows the curved path of the cable imposed by the curving device.

2. System according to claim 1 , in which said laser beam is normal to said marking plane.

3. System according to claim 1 , comprising moreover at least one cable holding device ( 7 ) configured to hold said cable at the site of said at least one cable curving device.

4. System according to claim 1 , comprising moreover at least one cable guiding device ( 6 ) configured to guide said cable, at least in said marking area.

5. System according to claim 1 , in which said at least one driving device comprises an adhering coating in contact with said cable.

6. System according to claim 1 , in which said at least one driving device comprises at least one drive belt ( 9 , 10 , 11 ) configured to drive said cable.

7. System according to claim 6 , in which said at least one driving device comprises at least one pair of drive belts ( 9 , 10 ) facing one another and configured to accommodate said cable between them.

8. System according to claim 1 , in which said driving device and said cable curving device are integrated in the same device ( 2 ).

9. System according to claim 1 , in which said at least one curving device comprises at least one wheel portion ( 15 , 17 ).

10. System according claim 9 , in which said at least one wheel portion ( 15 , 17 ) is configured to allow said cable to slide in said marking area.

11. System according to claim 9 , in which said wheel portion ( 17 ) comprises a plurality of rolling bearings for causing said cable to roll in said marking area.

12. System according to claim 9 , in which said at least one driving device comprises at least one drive belt configured to drive said cable, and said at least one wheel portion ( 25 ) is configured to allow said at least one belt to slide in said marking area.

13. System according to claim 12 , in which said wheel portion comprises a plurality of rolling bearings for causing said at least one belt to roll in said marking area.

14. System according to claim 9 , in which said at least one wheel portion ( 15 , 25 ) is stationary.

15. System according to claim 1 , in which said at least one driving device comprises at least one wheel ( 2 , 23 , 24 , 25 , 13 , 14 ) configured to perform a rotational movement.

16. System according to claim 9 , in which said laser device is configured to emit at least one laser beam in a direction perpendicular to the plane of said at least one wheel portion.

17. System according to claim 1 , in which said laser device is configured to emit at least one laser beam that moves as a function of the passage of said cable.

18. Cable marking method comprising the following steps:

driving said cable in order to cause it to pass through in a marking area,

curving said cable in said marking area, and

marking at least a portion of said cable in said marking area, by means of at least one laser device emitting at least one laser beam which, in the marking plane encompassing the surface of said cable, follows the curved path of the cable in the marking area.

19. System according to claim 9 , in which said at least one driving device comprises at least one pair of drive belts ( 9 , 10 ) facing one another and configured to accommodate said cable between them, and said at least one wheel portion ( 25 ) is configured to allow said at least one belt to slide in said marking area.
