Claim:
1. A method for impregnating a liquid material into a rope comprising a plurality of fibers and interstices between the fibers, wherein the method comprises the steps of: (a) providing a liquid material in a tank, wherein the liquid material defines a level of liquid in the tank; (b) providing an impregnation unit containing a chamber at least partially immersed in the liquid material, the chamber comprising: (c) providing a vacuum-device operatively connected to the vacuum-outlet for lowering pressure in the chamber below atmospheric pressure; (d) passing the rope through the liquid material in the tank and then inside and outside the chamber by the rope-inlet and the rope-outlet, respectively, while maintaining the pressure inside the chamber below atmospheric pressure to force the liquid material to fill at least part of the interstices between the fibers of the rope by penetrating between the fibers.
