Abstract:
The invention relates to a combined cable having a core cable made of high-strength plastic fibers present as a twisted monofilament bundle or a plurality of twisted monofilament bundles, and having an external layer of steel wire strands, characterized in that the monofilament bundle or bundles is or are stretched to reduce the diameter and held in a cladding, particularly braided cladding, in this state. The strain of the core cable under load is thus reduced, so that the load distribution between the steel cross-section and the plastic cross-section of the cable is improved. In the same sense, in reverse, in order to have the strain behavior of the strand layer approach that of the core cable, the cable has an intermediate layer made of an elastic plastic, in which the steel wire strands are pressed at a distance from each other, such that the external layer stretches under load and contracts radially.
Abstract:
The invention relates to a rope, and preferably a mooring rope. The rope comprises a core (2) of man-made fibres, a braided jacket (4) covering the core (2) and a particle barrier (5) between the core (2) and the braided jacket (4) . The particle barrier (5) comprises two layers (6) of filter material arranged onto the core (2) in such a way that the second layer (6b) is covering the firs layer (6a) .
