Abstract:
A composite reinforcing rope is made of a cylindrical core of twisted filaments of aromatic polyamides around which a plurality of steel wires of a rectangular configuration are coiled. The steel wires are wound side-by-side in one layer. Each wire is twisted around its own axis to such a degree that its broader side fully engages the periphery of the polyamide core. The edges of respective wires are rounded whereby the convex narrow dides of adjoining wires contact one another substantially along a line.

Abstract:
The invention relates to an abrasion resistant product comprising a plurality of interlaced yarns wherein at least a first yarn having a tensile strength, having a value TS in N/tex, said first yarn containing a plurality of UHMWPE fibres having a titer, having a value T in den, wherein the ratio T/TS is at least 5 den.tex/N.
Abstract:
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.
Abstract:
Ein Aufzugseil (1) weist mehrere miteinander verseilte Stahldrahtlitzen (3) aus verseilten Stahldrähten (4) und eine von den Stahldrahtlitzen (3) umgebene Seileinlage (2) auf, wobei die Seileinlage aus einem Faserbündel hochfester Kunststofffasern besteht.
Abstract:
The cross-sectional area or diameter of an electric cable subjected to tensile stresses is minimized by means of a central, fibre-shaped element consisting of a bundle of carbon fibres (11). This embodiment can be achieved in a longitudinally watertight version and is suitable for trouble-free implementation, for example in cable looms.
