Abstract

A method of wrapping elongate material with a sheath having first and second single-sided adhesive tapes the tapes laminated to one another with an offset, a free edge of the first adhesive tape aligned parallel to the center axis such that, relative to the center axis of the material, the adhesive of the first adhesive tape lies outwards, the first adhesive tape of the sheath guided by the free edge onto the material, and wound around the material so that the first adhesive tape essentially completely envelopes the material, the second adhesive tape also wound around the material, the exposed adhesive of the second adhesive tape bonding to the exposed adhesive of the first adhesive tape, so that the material is surrounded by at least two plies of adhesive tape.

First claim

What is claimed is:

1. A combination comprising elongate material wrapped with a sheath;
the elongate material having a width, a length longer than the width and a center axis parallel to the length;
the sheath comprising first and second adhesive tapes;
each of the first and second adhesive tapes comprising an adhesive side and a non-adhesive side;
each of the first and second adhesive tapes having a leading edge, a trailing edge opposite said leading edge and a width;
the leading edge and the trailing edge of each of the first and second adhesive tapes oriented essentially parallel to said center axis;
the width of each of the first and second adhesive tapes extending perpendicular to said center axis;
the first and second adhesive tapes being laminated to one another through their respective adhesive sides to form a laminated area of the first and second adhesive tapes that comprises the trailing edge of the first adhesive tape overlapping and laminated to the leading edge of the second adhesive tape with an offset;
the first adhesive tape being wound around the elongate material so that the first adhesive tape essentially completely envelops the elongate material;
the adhesive side of the first adhesive tape being farther away from the elongate material than the non-adhesive side of the first adhesive tape; and
the second adhesive tape being wound around the elongate material and the first adhesive tape in such a way that the adhesive side of the second adhesive tape is bonded to and contacts the adhesive side of the first adhesive tape and the elongate material is always surrounded by at least two plies of adhesive tape.

2. The combination according to claim 1 , wherein any exposed adhesive of the first adhesive tape is completely covered by the second adhesive tape.

3. The combination according to claim 1 , wherein a third single-sided adhesive tape is laminated onto the leading edge of the first adhesive tape, in each case on the adhesive side, with an offset, the third adhesive tape having a narrower width than the first adhesive tape.

4. The combination according to claim 3 , wherein the sheath and also the sheath with the third adhesive tape are present in fixed lengths.

5. The combination according to claim 1 , wherein the sheath has a width of 50 to 400 mm.

6. The combination according to claim 5 , wherein the sheath has a width of 80 to 280 mm.

7. The combination according to claim 3 , wherein the first adhesive tape has a width of 40 to 140 mm, the second adhesive tape has a width of 40 to 140 mm and/or the third adhesive tape has a width of 20 to 40 mm.

8. The combination according to claim 1 , wherein the first adhesive tape is laminated onto the second adhesive tape with an offset of 5% to 20% relative to the width of the adhesive tape.

9. The combination according to claim 3 , wherein the third adhesive tape is laminated onto the first adhesive tape with an offset of 40% to 60% relative to the width of the adhesive tape.

10. The combination according to claim 3 , wherein a backing material of the first, second and/or third adhesive tape is composed of a loop product or of a velour, lay, woven or formed-loop knit.

11. The combination according to claim 10 , wherein the backing material is composed of a PET filament woven or a nylon woven.

12. The combination according to claim 3 , wherein the adhesive of the first, second and/or third adhesive tape is a self-adhesive composition.

13. The combination according to claim 12 , wherein the self-adhesive composition is a rubber or acrylate or silicone adhesive.

14. The combination according to claim 1 , wherein the elongate material is a cable harness.

15. A vehicle comprising the combination according to claim 1 .

16. The vehicle according to claim 15 , which is an automobile.

17. The vehicle according to claim 16 , wherein the elongate material is a cable harness.
