  • a further alternative for producing a cable region 10 widened by loops is to design a guide in a receptacle (made of plastic, for example) through which the cable can be passed, such that the cable is forcibly guided when the cable is being carried through the receptacle is placed in at least one loop. Subsequently, a suitable flowable filling compound is then injected into the receptacle.
  • FIG. 8A shows a carrier element 6, which, in a modification of the carrier element 5 from FIG. 6A, extends substantially in a straight line and has a circumferential surface 60 that runs annularly in cross section and that defines, for example, a cylindrical carrier 6.

Abstract

L'invention concerne un câble en fibres synthétiques qui comprend une surface extérieure (12) entourant l'âme du câble (1), des interstices entre composants (15) du câble étant ménagés dans l'âme du câble (1), ainsi qu'un élément de transmission de force (2, 7) servant à transmettre une force agissant sur le câble (1) à un élément (4, F) placé en aval. A cet effet, le câble (1) présente un élargissement dans au moins une zone (10) de sorte que des espaces libres (16) sont formés entre les composants de câble (15) dans cette zone (10). Ces espaces libres ont une dimension en section transversale supérieure à celle des interstices dans l'âme du câble (1) à l'extérieur de cette zone (10) du câble et sont remplis d'une matière de remplissage (7) pour la formation de l'élément de transmission de force (2, 7).
