A device for degreasing pieces such as optical fibers of a stripped cable comprises a tank containing a liquid solvent in which the pieces are immersed, a pressurized gas container having a gas outlet nozzle, a receptacle for holding the container vertical with the nozzle at the bottom, and a diffuser for gas passing from the nozzle into the liquid solvent below the pieces. The gas diffused into the solvent is cold and causes turbulence of the solvent. The grease is detached from the pieces and falls into a cavity.

Degreasing device particularly for optical fibers

An apparatus cuts one or several optical fibers obliquely. The cutting edge (6) creates the beginning of a break on the fiber that has first been subjected to a torsion and to a tension. The fiber is immobilized upstream of the cutting point. Then, the fiber is tightened downstream from the cutting point. Next, a tension is exerted on the part of the fiber or fibers located between the application of the tightening (3,4). The tightening also involves an exertion of a torsion force upon the optical fiber.
