Document Type and Number:
WIPO Patent Application WO/2013/128006
Kind Code:
A3
Abstract:
A method for impregnating a liquid material (105) into a rope (101) comprising a plurality of fibers and interstices between said fibers, said method comprising the steps of: (a) Providing a liquid material in a tank, (104) said liquid material defining a level of liquid (105-1) in said tank (104); (b) Providing an impregnation unit (103) containing a chamber (106) at least partially immersed in said liquid material (105), said chamber (106) comprising: (i.) a rope-inlet (107) for at least partially tightly receiving the rope (101), wherein said rope-inlet (107) is positioned below the level of liquid (105-1); (ii) a rope-outlet (108) for at least partially tightly discharging said rope (101); iii) a vacuum-outlet (109); and (c) Providing a vacuum-device operatively connected to said vacuum-outlet (109) for lowering the pressure in said chamber (106) below the atmospheric pressure; (d) Passing the rope (101) through the liquid material (105) in the tank (104) and then inside and outside said chamber (106) via the rope-inlet (107) and rope-outlet (108), while maintaining the pressure inside said chamber (106) below the atmospheric pressure to force the liquid material (105) to fill at least part of said interstices between the fibers of the rope (101) by penetrating between said fibers. A corresponding device, rope an use of the rope is also disclosed.
