Abstract

The sealing tape for sealing a joint has a first foam strip with a top surface and a bottom surface, a second foam strip with a top surface and a bottom surface, and a sheet-like connecting element, which comprises a first attachment section, a second attachment section, and a middle section between the two attachment sections. The first attachment section is attached to the first foam strip; the second attachment section is attached to the second foam strip; and the middle section extends from the top surface of the first foam strip to the bottom surface of the second foam strip when the middle section is stretched out straight.

Claims

1-17. -17. (canceled)

18. A sealing tape for sealing a joint, comprising:

a first foam strip having a top surface and a bottom surface,

a second foam strip having a top surface and a bottom surface, and

a sheet-like connecting element, which comprises a first attachment section, a second

attachment section, and a middle section between the first and second sections, wherein at least part of the first attachment section is attached to the first foam strip, at least part of the second attachment section is attached to the second foam strip, and the middle section extends from the top surface of the first foam strip to the bottom surface of the second foam strip when the middle section is stretched out straight.

19. The sealing tape of claim 18 wherein the middle section of the sheet-like connecting element is not attached to the first or to the second foam strip.

20. The sealing tape of claim 18 wherein a first pressure-sensitive adhesive layer, which is covered by a cover sheet, is arranged on the bottom surface of the first foam strip.

21. The sealing tape of claim 20 wherein a second pressure-sensitive adhesive layer, which is covered by a second cover sheet, is arranged on the bottom surface of the second foam strip.

22. The sealing tape of claim 21 wherein the second pressure-sensitive adhesive layer is arranged under the second attachment section of the sheet-like connecting element.

23. The sealing tape of claim 21 wherein the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer are designed as integral parts of each other and are formed by a one-piece, stretchable pressure-sensitive adhesive strip.

24. The sealing tape of claim 21 wherein a third pressure-sensitive adhesive layer, which is covered by a third cover sheet, is arranged on the top surface of the first foam strip.

25. The sealing tape of claim 24 wherein a fourth pressure-sensitive adhesive layer, which is covered by a fourth cover sheet, is arranged on the top surface of the second foam strip.

26. The sealing tape of claim 25 wherein the third pressure-sensitive adhesive layer is arranged above the first attachment section of the sheet-like connecting element.

27. The sealing tape of claim 18 wherein the first attachment section and the second attachment section of the sheet-like connecting element are attached to the first and second foam strips by means of first and second adhesive layers.

28. The sealing tape of claim 18 wherein the first attachment section or the second attachment section of the sheet-like connecting element comprises openings.

29. The sealing tape of claim 18 wherein the top surface of the second foam strip is shorter than the bottom surface of the second foam strip, and the bottom surface of the first foam strip is shorter than the top surface of the first foam strip.

30. The sealing tape of claim 18 wound up into a sealing tape roll, wherein the first foam strip and the second foam strip are wound up next to each other around a winding tube.

31. The sealing tape of claim 18 wound up into a sealing tape roll, wherein the first foam strip and the second foam strip are wound up on top of each other around a winding tube.

32. A structural component to which a sealing tape for sealing a joint is attached, the sealing tape comprising:

a first foam strip having a top surface and a bottom surface,

a second foam strip having a top surface and a bottom surface, and

a sheet-like connecting element, which comprises a first attachment section, a second

attachment section, and a middle section between the first and second sections, wherein at least part of the first attachment section is attached to the first foam strip, at least part of the second attachment section is attached to the second foam strip, and the middle section extends from the top surface of the first foam strip to the bottom surface of the second foam strip when the middle section is stretched out straight;

wherein the first foam strip and the second foam strip are arranged next to each other, and an intermediate space, through which the middle section of the sheet-like connecting element extends, is formed between the first and second foam strips.
