(4) FIG. 4 is a simplified perspective view of part of a piece of the winding tape according to the second variant embodiment.

DETAILED DESCRIPTION OF THE INVENTION

(5) Referring now to the figures of the drawings in detail and first, particularly, to FIGS. 1 and 2 thereof, there is seen a cable set which is only illustrated in detail and incompletely and includes a bundle of lines or a line run 2 having a plurality of individual lines 4 which are disposed in several layers in the exemplary embodiment. These lines 4 are, in particular, electrical power and/or data lines which are electrically insulated from one another. It is also possible to provide other types of lines, such as hydraulic, pneumatic lines, etc. for example, in principle. However, the lines are preferably exclusively electrical lines.

(6) The entire line run 2 is surrounded by a taping 6 which covers the line run 2 over the entire surface in the exemplary embodiments, so that no clearances are formed. The taping 6 itself includes a winding tape 8 on which nubs 10A, 10B are integrally formed on the radially outer face. In this case, the winding tape 8 is preferably a plastic tape in the case of which the individual nubs 10A, 10B are also integrally formed. As an alternative, the winding tape 8 can also be a textile carrier tape on which nubs which are composed of a different material are fitted in a suitable way, for example by adhesive bonding or by textile processing techniques. The winding tape is wound overall in a spiral manner around the line run 2.

(7) The initial state of the winding tape 8 is illustrated in each of FIGS. 3 and 4. The winding tape 8 is preferably a continuous piece goods item which is, for example, wound up into a roll and unwound to form the taping 6.

(8) In the first variant embodiment according to FIGS. 1 and 3, conical nubs 10A are formed with a cylindrical cone base and a cone tip adjoining the cone base. As can be seen in FIG. 3 in particular, in this case several individual nubs 10A are disposed in the longitudinal direction of the winding tape 8, in two rows in the exemplary embodiment, wherein the individual nubs 10A of a respective row are distributed equidistantly in relation to one another in the longitudinal direction. In the exemplary embodiment, the two rows are offset in relation to one another by the distance between two nubs 10A which follow one another in the longitudinal direction.

(9) In the second variant embodiment according to FIGS. 2 and 4, the nubs 10B are, in contrast, in the form of webs, the length of which is a multiple of their width. In the exemplary embodiment, the webs are approximately in the form of rectangular structures with rounded edge regions.

(10) As is shown in FIG. 4 in particular, the nubs 10B are disposed in an approximately V-shaped manner in relation to one another, that is to say they are oriented alternately obliquely at the same angle in relation to the longitudinal direction of the winding tape 8 overall. The length of the web-shaped nubs 10B at least approximately reaches the width of the winding tape. Due to this configuration, a large supporting surface is formed on one side by the radially outer face of the nubs 10B. At the same time, it is ensured that the material for forming the protective sheath can reliably flow around the individual nubs 10B during the production process.

(11) The height of the nubs 10A, 10B is typically several millimeters, for example three to ten millimeters. In this case, the height of the nubs also corresponds, in particular, to the minimum wall thickness of a protective sheath 11 which surrounds the line run in the final state.

(12) This protective sheath 11, which is only partially illustrated in broken lines in FIG. 1 so as not to obscure the other elements, but is also provided in the embodiment of FIG. 2, is produced by an injection molding process, a casting process and in particular a foaming process. At least some of the nubs 10A, B may pass through the protective sheath 11. To this end, the line run 2 around which the winding tape 8 is wound is placed into a mold and the injection molding, casting or foaming material for forming the protective sheath 11 is then introduced into the mold. After curing, the cable set which is then finished is removed from the mold. Plugs or the like which are, for example, also embedded in the protective sheath 11 are expediently already fastened to the ends of the individual lines 4.

(13) In order to allow simple preparation of the line run 2, the winding tape 8 has an adhesive construction and has an adhesive layer on its inner face which is opposite the nubs 10A, 10B, so that the winding tape 8 adheres well to the lines 4 and does not slip when being wound around the line run 2.

(14) With respect to the intended application of a cable set of this kind, in particular in a motor vehicle, the winding tape 8 is preferably temperature-resistant up to temperatures of 100° C. and, in particular, up to temperatures of 150° C., so that a cable set of this kind is in particular also suitable for laying in the engine compartment. Furthermore, the winding tape 8 is also media-resistant, that is to say suitable for harsh environmental conditions in which it may come into contact with media, such as cooling liquid, oil, etc. for example.

(15) The production of a cable set is simplified and is also made less expensive overall by virtue of the winding tape 8, which is also called a nubbed tape, and is described herein as having the nubs 10A, 10B formed on it. Firstly, a rib structure which is otherwise required in the die can be dispensed with. Due to the nubs 10A, 10B, the line run 2 is situated in a centered manner overall in a corresponding cavity in the mold. Damage to the individual lines, for example when the mold is closed, is also at least virtually precluded. In this case, the dimensioning of the individual nubs 10A, 10B is expediently selected in conjunction with the line run 2 in such a way that the line run 2 around which tape is wound is clamped within the respective cavity in the die. This is not particularly critical since there is no fear of damage to the individual lines 4 as a result. However, at the same time, a strong centering effect is achieved as a result and the configuration of separate holding-down devices or other holders on the mold is not required and accordingly not provided either. Overall, it is possible to lay the prepared line run 2 into the mold more quickly and more simply during production as a result. At the same time, a strong protective function for the individual lines 4 is simultaneously ensured. In addition, this ensures, overall, that the lines 4 are not visible from the outside.
