  • Patent number: 4849038
    Abstract: The invention concerns a method for depositing an interlining reducing friction and noise on a pitched cable consisting of a metal wire rope with a threaded helix. The preferred method consists in using a thermoplastic filament and raising the pitched cable to a temperature higher than the melting point of the thermoplastic used, and thereupon, winding the filament between the heated threads of the helix so that the flocks or hairs fuse or sinter to the metal wire and adhere.

  • Patent number: 4625504
    Abstract: A pitched cable is sheathed over a defined length with a plastic polyamide film. The method includes the steps of slipping a plastic polyamide tube over a pitched cable and affixing this tube to the cable by hammering. An additional procedural step is also described, namely the prior reduction of the outside diameter of the pitched cable, so that with appropriate dimensions of the plastic tube, it is possible to make a plastic sheathing for the pitched cable, with the outside diameter of the plastic tube then being only trivially larger than the outside diameter of the unsheathed cable length.
