In the event of an overload break in the rope, these threads or monofilaments are intended to reduce the potential energy present when the mainly load-bearing plastic threads break.

  • the proportion of the staple fiber yarns or the multi-filament filaments in the sheath can be selected accordingly depending on the intended use, ie on the desired grip properties or the desired service life of the rope element.
  • Multifilaments are strands that are formed from a large number of continuous fibers.
  • the sheath has at least two different materials, the one material, which may be in the form of multifilaments, having a longer service life than that other material, which may be in the form of staple fiber yarn.

Abstract

L'invention concerne un élément de corde (2, 11) à structure torsadée ou tressée, comportant une âme (3) et une gaine (5) qui sont constituées de différentes matières synthétiques. Des multifilaments (8; 10) et/ou des fils de fibres discontinues (7; 9) sont présents dans la gaine (5). Des cordes torsadées, notamment des cordes à usage industriel, par exemple des cordes de guidage de papier, peuvent être formées à partir d'au moins un élément de corde (2, 11) selon l'invention.
