    Abstract

    The invention relates to an adhesive strip, in particular a winding strip for sheathing cables in automobiles, comprising a textile support (1.2) that has at least one first fabric (1) and a second fabric (2) which are connected together and comprising an adhesive coating (5) on at least one face of the support (1, 2). According to the invention, the two fabrics (1, 2) are preferably coupled together solely by connection threads (3) of the fabrics.

    Claims

    1. An adhesive tape for wrapping cables in automobiles, comprising: a textile substrate having at least one first textile web and a second textile web that are connected together; and an adhesive coating on at least one face of the substrate; and, connection filaments of the textile webs interconnecting the first and second textile webs.

    2. The adhesive tape according to claim 1, wherein the connection filaments are warp filaments and/or weft filaments of the first textile web.

    3. The adhesive tape according to claim 1, wherein the connection filaments are warp filaments and/or weft filaments of the second textile web.

    4. The adhesive tape according to claim 1, wherein the two textile webs each have the same weave.

    5. The adhesive tape according to claim 1, wherein the two textile webs are of different weaves.

    6. The adhesive tape according to claim 1, wherein the connection filaments are weft filaments of the first textile web that cross one or more warp filaments of the second textile web.

    7. The adhesive tape according to claim 1, wherein the connection filaments are warp filaments of the first textile web that cross one or more weft filaments of the second textile web.

    8. The adhesive tape according to claim 1, wherein the filaments of the first and second textile webs have a fineness of more than 100 dtex and in particular 150 dtex and more.

    9. The adhesive tape according to claim 1, wherein the filaments of the first and second textile webs are polyester filaments and/or polyamide filaments and/or inorganic filaments of metal, carbon or glass or combinations thereof.

    10. The adhesive tape according to claim 1, wherein the adhesive tape a wrapping tape guided spirally or helically around a cable or a longitudinal wrapping closed around the cable to be wrapped.

    Description

    [0025] The invention is explained in greater detail below with reference to drawings that show only one embodiment, and in which:

    [0026] FIG. 1 is a sectional schematic view of the adhesive tape according to the invention,

    [0027] FIG. 2 shows the two interconnected textile webs of the textile substrate before they are combined and

    [0028] FIG. 3 shows the substrate according to the invention with the connection filaments for coupling the two textile webs.

    [0029] The figures show an adhesive tape that is advantageously a tape for wrapping cables in automobiles. In this case, in principle, for the purpose of longitudinal wrapping or tubular wrapping the wrapping tape can be closed in a longitudinal direction around the cable to be wrapped. Alternatively, the adhesive tape that is illustrated and is still to be described in greater detail can also be wound spirally or helically around the cable to be wrapped. This is the usual procedure.

    [0030] The adhesive tape according to the invention has a textile substrate 1, 2. According to this embodiment and without limitation, the textile substrate is made up of a first textile web 1 and a second textile web 2. Both textile webs 1, 2 or fabric layers according to the invention are mechanically coupled together according to the invention, that is to say by connection filaments 3 of the textile webs. The is indicated in FIG. 1. The connection filaments 3 illustrated there are weft filaments 3 of the first textile web 1 that cross one or more warp filaments 4 of the second textile web 2 as shown. In the sectional view according to FIG. 1 it is possible to see, in each case in section, the warp filaments 4 both of the first textile web 1 and also of the second textile web 2. On the other hand, the associated weft filaments 3 of the textile webs 1, 2 are not explicitly illustrated, and for the sake of clarity only one connection filament or weft filament 3 is shown by way of example.

    [0031] The textile substrate 1, 2 of the adhesive tape according to the invention is provided with an adhesive coating 5. In fact, the adhesive coating 5 is applied over the entire surface or as a strip coating on the rear face of the second textile web or the second fabric layer 2. In the installed state of the adhesive tape according to the invention the first textile web or the first fabric layer 1 is directed outward. In order to protect this first textile web 1, in principle a coating 6 can also be provided that is indicated by dot-dash lines in FIG. 1. However, such an additional coating 6 is usually unnecessary.

    [0032] The detailed structure of the substrate 1, 2 is shown clearly with reference to FIGS. 2 and 3. The two textile webs 1, 2 can actually be seen in individual views in FIG. 2. In this case the first textile web 1 is a plain weave. In other words, the individual weft filaments 3 alternately pass over and under the warp filaments 4. On the other hand, the second textile web 2 has a different weave. In fact, in the present case the second textile web 2 is provided with an atlas or satin weave. In this case the weft filaments 3 pass over one warp filament 4 and then under more than two warp filaments 4.

    [0033] FIG. 3 shows how, the connection filament or weft filament 3 in this case of the second textile web 2 individual warp filaments 4 of the first textile web 1 are crossed and as a result the required mechanical connection is made between the two textile webs 1, 2. In other words, FIG. 3 shows a somewhat modified embodiment by comparison with FIG. 1 in such a way that in this case the connection filament 3 is formed as a weft filament of the second web 2 (with the atlas weave or satin weave) that crosses one or more warp filaments 4 of the first textile web 1. On the other hand, the connection filament 3 according to FIG. 1 is a weft filament of the first textile web 1 that crosses one or more warp filaments 4 of the second textile web 2. Both fundamental configurations are possible.

    [0034] Thus, the filaments of the textile web 1, 2, that is to say both the warp filaments 4 and also the weft filaments 3, like the connection filaments 3, have an overall fineness of more than 100 dtex. In fact fineness values of 200 dtex and more are usually used. The filaments 3, 4 of the textile web 1, 2 can be formed in each case as polyester filaments. In principle, however, they can also be polyamide filaments. In addition, inorganic filaments 3, 4 such as metal filaments, carbon filaments, glass filaments etc. are also possible. Combinations are also conceivable and are covered by the invention.
