Problems solved by technology

[0005] Overall, the two-stage approach is more expensive
This also often leads to a not very satisfactory design solution for cables that are visible in the state of use and used, for example, by the end user

Embodiment Construction

[0053] figure 1 and 2 The shown cables 2 each extend in a cable longitudinal direction 4 and comprise a cable core 6 which is surrounded by an outer sheath 8 . The outer sheath 8 is formed here from individual sheath sections 10 directly adjoining one another. In the final produced state, the sheath sections 10 cannot be identified individually due to the special shaping method that will be described later, ie the points where the individual sheath sections 10 adjoin one another cannot be discerned.

[0054] The outer sheath 8 is a protective or insulating sheath, typically constructed of a hardenable plastic polymer substance. The cable core 6 is one or more electrical conductor cores 12 , which are present, for example, as bundled individual cores or also as coaxial wires or the like. The cable core 6 can also have a complex structure made up of different cable parts. Here too, optical transfer fibers and / or other components can be integrated into the cable core 6 . Pre...

Abstract

In order to manufacture a cable (2) comprising a cable core (6) and an outer sheath (8) extending in the cable longitudinal direction (4), in a continuous forming process, each sheath of the outer sheath (8) The sheath section (10) is formed continuously by encasing the cable core (6) with a hardenable plastic substance, wherein in at least one partial section (14) a belt is produced in the longitudinal direction of the cable. (4) Outer sheath (8) of altered cross-sectional geometry.

Description

technical field [0001] The invention relates to a method for producing a cable extending in the longitudinal direction of the cable, in particular with a cable core and an outer sheath surrounding the cable core. Furthermore, the invention also relates to cables and molds used in the method. Background technique [0002] The outer sheath in such cables is usually constructed by molding methods from a plastic substance which can set during the manufacturing process. In this case, first a liquid or viscous plastic substance is applied, which then solidifies. This takes place, for example, by coagulation itself or actively by delivering (activating) energy, for example by radiation or the like, so that active hardening is achieved. Subsequently, the term "curing" encompasses passive solidification and active hardening, unless otherwise stated from the specification. [0003] Usually, other additional functional units are integrated into the outer sheath. Thus, for example, ...
