Abstract

An adhesive tape for the flying roll change of flat web material wound on rolls has a carrier having a leading side and a trailing side. An optically detectable means and an exposable self-adhesive compound are arranged on the leading side. A cleavable adhesive system is located on the trailing side. An inductively detectable means is arranged in the adhesive tape in a visually inconspicuous manner.

Claims

1. An adhesive tape for the flying roll change of flat web material wound on rolls, comprising (a) a carrier having a leading side and a trailing side, (b) an optically detectable means arranged on the leading side, (c) an exposable self-adhesive compound arranged on the leading side, (d) a cleavable adhesive system arranged on the trailing side, and (e) an inductively detectable means arranged in a visually inconspicuous manner on either the leading side or the trailing side.

2. Adhesive tape according to claim 1, wherein the inductively detectable means comprises a metal foil.

3. Adhesive tape according to claim 1, wherein the inductively detectable means is arranged on the trailing side of the carrier and is provided with a visually inconspicuous cover layer.

4. Adhesive tape according to claim 3, wherein the visually inconspicuous cover layer comprises printing ink.

5. Adhesive tape according to claim 1, wherein the inductively detectable means is arranged on the leading side of the carrier and is concealed by the optically detectable means.

6. Adhesive tape according to claim 1, wherein the optically detectable means comprises an optically detectable layer.

7. Adhesive tape according to claim 1, wherein the optically detectable means comprises a colored addition to the self-adhesive compound.

8. Adhesive tape according to claim 1, wherein the self-adhesive compound is covered by a detachable cover.

9. Adhesive tape according to claim 8, wherein the detachable cover is segmented.

10. Adhesive tape according to claim 1, wherein the cleavable system comprises a single-layer paper which on one side is connected via a first adhesive compound to the trailing side of the carrier or a layer arranged between the trailing side of the carrier and the first adhesive compound and which single-layer paper comprises on its opposing second side a second adhesive compound which can optionally be covered, wherein the single-layer paper is cleavable and after cleavage cleaves into two remains, a first of which two remains covers the first adhesive compound and a second of which two remains covers the second adhesive compound.

11. Adhesive tape according to claim 10, wherein the first adhesive compound and/or the second adhesive compound comprises an activatable adhesive compound, a curing adhesive compound and/or a self-adhesive compound.

12. Adhesive tape according to claim 1, wherein the cleavable system comprises a second carrier, which is connected by means of a coat to the trailing side of the carrier or to a layer arranged between the trailing side of the carrier and the coat, a side of the second carrier opposing the coat being provided with an adhesive compound and the coat being configured in such a way that when the cleavable system cleaves a separation takes place at a boundary layer of the coat or within the coat.

13. Adhesive tape according to claim 1, wherein the cleavable system comprises a composite comprising paper/paper, paper/foil material or foil material/foil material.

14. Adhesive tape according to claim 1, wherein the self-adhesive compound comprises on the leading side at least substance selected from the group consisting of acrylate, natural rubber, and synthetic rubber.

15. Adhesive tape according to claim 1, wherein the self-adhesive compound on the leading side exhibits a rolling distance length of less than 40 mm.

16. Adhesive tape according to claim 1, wherein the self-adhesive compound on the leading side exhibits a rolling distance length in the range of from 40 mm to 100 mm.

17. Adhesive tape according to claim 1, wherein the carrier comprises a kraft paper.

18. A method of splicing a new roll of flat web material to an old unwinding roll of flat web material, said method comprising applying an adhesive tape according to claim 1 to a leading edge of said new roll of flat web material, setting said new roll of flat web material with the applied adhesive tape in motion, and contacting a trailing edge of said old unwinding roll of flat web material with the leading edge of said new roll of flat material while both are moving to splice the new roll of flat web material to the old unwinding roll of flat web material via said adhesive tape.
