Abstract (en)
[origin: WO2004020732A2] A rope with high stiffness and breaking strength is provided. The rope is produced by providing a stiff core (1) and fibre rope jacket (4) surrounding the core and by changing the phase condition of the core while stretching the rope, such that inside vacancies between the fibre rope jacket (4) and the core (1)are eliminated permanently. A method and apparatus for producing such rope are provided, wherein the core (1) is heated up and stretched such that it will be permanently elongated. In a preferred embodiment the thermoplastic core (1) changes from solid phase to liquid phase by means of heating. While in liquid phase the core material adapts to the encapsulating space of the surrounding sheet. The rope is then cooled down under tension until the core has returned to solid phase.
