- a particularly cheap solution especially for a complete one Enclosing the cable core, provides that the retroreflective material in the longitudinal direction of the Cable extending band forms the circumferential direction of the Cable core and across its longitudinal direction around the cable core or if necessary one arranged on the cable core Inner jacket is turned over and the cable core and optionally surrounds an inner jacket.
- Such a surrounding of cable core and possibly Inner jacket does not necessarily require that the side edges abut the ribbon. There is a possibility to provide these at a distance from each other. It exists but also the possibility of joining the side edges together nudge or preferably overlap to complete Enclosing the cable core and, if necessary, one To reach the inner jacket.
- the retroreflective flat material forms the cable sheath.
- this flat material has such stability that it is in the Is able, the cable core and / or possibly an inner jacket to protect adequately.
- the retroreflective is required Flat material on the cable core or the Inner jacket is fixed, for example by an adhesive layer or in that the reflective sheet one closed in the azimuthal direction around the longitudinal axis tubular sleeve for the cable core and possibly forms an inner jacket and thus on one the same is positively fixed by the enclosing.
- the retroreflective Flat material is surrounded by an outer jacket of the cable, the outer sheath of the cable preferably being formed in this way is that it is transparent to the desired light.
- the outer jacket is made of one for visible light made of transparent material.
- the outer jacket of the cable is preferred also made of transparent material for the desired light, preferably transparent for visible light Material, manufactured.
- a particularly inexpensive solution is the retroreflective one Elements in the form of pieces retroreflective Embed flat material in the cable sheath.
- Another advantageous possibility provides that in the Cable sheath the optical elements of the retroreflective Elements are embedded, while the reflector layer from Cable sheath is enclosed.
- the cable core or to surround an inner jacket with a reflector layer and then embed the optical elements in the cable sheath, which then together with the reflector layer the retroreflective Elements result.
- the retroreflective elements are composed of an optical element and a reflector layer the most different possibilities conceivable.
- the reflector layer at a distance from the optical element, for example separately through a spacer layer.
- the optical elements are preferably designed as glass bodies. It is particularly favorable to use glass microbeads as glass bodies to use.
- a first embodiment of an inventive Cable designated as a whole in Fig. 1 with 10, comprises a Cable core 12, for example, from a variety of juxtaposed single wires 14 with one of these enclosing insulation jacket 16 is formed.
