- Figure 3 shows the real-time surveillance area on an enlarged scale of the wrapping process.
- the optical measuring device 16 makes it possible to check the degree of vibration 73 of the ribbon of the wired element 4B before its winding on the strand 6A of the main cable 6. Analysis of the vibration by the data processing circuit 17 allows regulation of the mechanical tension exerted on the ribbon by the brake 53F. Point is also monitored by the optical measuring device 16 in zone 8, so as to obtain optimum installation precision at level of the overlap and the pitch of the turns of the ribbon, and to detect any crease or flipping the ribbon.

- the operation of the assembly machine can be carried out in two distinct modes:
- the user can intervene at any time on the previously mentioned settings, as well as on the settings of the assembly machine.
- the ambient temperature or the relative humidity directly influences the behavior of the wire element 4.
- the path taken by the wire element can suddenly or gradually cause a difficulty (blocked guide wheel, dirty guide, ...) consequently increasing the tension of the wire element 4, and disturbing the positioning of the wire element 4 relative to main cable 6 previously adjusted.
- Other parameters can influence the removal of the wire element 4, in particular in the event of a dimensional defect (width or diameter).
- the resident program of the EPROM 80 memory provides for slaving the assembly machine on the position and vibration of the wire element 4 compared to main cable 6A.
- the resident program allows you to order active components of device 15 to catch up with the drift observed (position of the wired element, vibration of the wired element) by priority orders previously programmed at memory level EPROM 80.
- the program allows you to act on the setpoint rotation of the winding head 50, by accelerating or decelerating the head winding 50, or on the drawing setpoint of the take-up reel 55 in accelerating or decelerating the draw of cable 6B, or by acting on the setpoint of the mechanical tension applied to the wire element which influences also on its position.
- the order of priority of intervention on the active components can at any time to be changed by the assembly machine user to contribute to optimum positioning of the wire element 4 relative to the main cable 6, and / or minimize or increase the vibration of the wire element 4.
- the 80 resident EPROM memory program is designed to stop the assembly machine.
- Real-time monitoring of the installation of the wire element 4 and its vibration is associated with traceability, which informs the user of the observed drifts, in order to know on a given production the level resulting quality, and to know the manufacturing process concerning such or such product by associating the manufacturing times, the speeds of manufacturing (rotation of the winding head, ...) and possible stops (change of the wire element for example).
- This monitoring of the wire element also allows to know the possible drift following parameters external to the assembly machine (room temperature, humidity, ).
- Auxiliary sensors 82 for this purpose transmit the temperature and humidity measurements to the microprocessor 75.
