OPTICAL FIBRE TENSIONING DEVICE AND METHOD OF CONTROLLING THE TENSION APPLIED TO AN OPTICAL FIBRE

Optical fibre tensioning device, receiving at its input an optical fibre (35) from a traction device (37) and capable of supplying the optical fibre from its output to a device (40) for storing the fibre. The tensioning device (1) comprises at least one fixed pulley (32) on which the optical fibre (...

Beschreibung
Zusammenfassung:	Optical fibre tensioning device, receiving at its input an optical fibre (35) from a traction device (37) and capable of supplying the optical fibre from its output to a device (40) for storing the fibre. The tensioning device (1) comprises at least one fixed pulley (32) on which the optical fibre (35) is wound, for a certain length. at least, and at least one movable pulley (9) on which the optical fibre (35) is wound, for a certain length at least. A device for measuring the tension applied to the fibre and a motorized device (24, 26, 5, 7) for moving the movable pulley (9) interact with each other to control the distance (Dp) between the axes (33, 20) of the pulleys (32, 9) in such a way as to automatically keep the tension applied to the fibre essentially constant.
