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 the longitudinal direction 4 of the cable and comprise a cable core 6 which is surrounded by an outer sheath 8 . The outer jacket 8 is formed here from individual jacket sections 10 which directly adjoin each other. In the final produced state, the sheathing sections 10 cannot be individually identified due to the special molding method described later, ie the areas where the individual sheathing sections 10 adjoin each other are not discernible.

[0054] The outer sheath 8 is a protective or insulating sheath, usually constructed of a hardenable plastic polymer substance. The cable core 6 is one or more electrical conductor cores 12, which exist, for example, as bundled individual cores or also as coaxial wires or the like. The cable core 6 may also have a complex structure composed of different cable components. In this case, optical transmission fibers and / or other components can also be integrated into the cable c...

Abstract

The invention relates to the production of an electrical line (2) which extends in the longitudinal direction (4) of the line and comprises a line core (6) and an outer shell (8), wherein, in a continuous shaping process, individual shell portions (10) of the outer shell (8) are formed successively by surrounding the line core (6) with a curable plastic substance, wherein, in at least one portion (14), the outer shell (8) is produced having a cross-sectional geometry which can be varied in the longitudinal direction (4) of the line.

Description

technical field [0001] The present 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 present invention also relates to cables and moulds used in the method. Background technique [0002] The outer jacket in such cables is usually constructed by forming methods from a plastic substance that solidifies during the manufacturing process. Here, a liquid or viscous plastic mass is first applied, which then solidifies. This is achieved, for example, by solidification itself or actively by supplying (activating) energy, for example by radiation or the like, so that active hardening is achieved. Subsequently, the concept "hardening" includes both passive solidification and active hardening, if it is not described differently from the specification. [0003] Typically, other additional functional units are integrated into the outer...
