Splicing adhesive tape comprising splittable connector elements

1. An adhesive splicing tape comprising a first carrier and a first splittable connecting element having a left-hand (l) and a right-hand (r) bounding edge, at least one of these two edges (l, r) being nonrectilinear and having projections (V) which are rounded at their furthest projecting points (v), and also a second splittable connecting element having a left-hand (L) and a right-hand (R) bounding edge, at least one of these two edges (L, R) being rectilinear, the first and second splittable connecting elements being disposed adjacent one another on the carrier, and the first splittable connecting element being present in the form of a multiplicity of individual sheetlike elements.

2. The adhesive splicing tape of claim 1 , the first and second splittable connecting elements being disposed adjacent one another on the first carrier in such a way that they are not themselves in direct contact with one another.

3. The adhesive splicing tape of claim 1 , the first and second splittable connecting elements being disposed adjacent one another on the first carrier in such a way that a nonrectilinear bounding edge (l, r) of the first splittable connecting element and a rectilinear bounding edge (L, R) of the second splittable connecting element are facing away from one another.

4. The adhesive splicing tape of claim 1 , the first and second splittable connecting elements having a distance of 3-50 mm to one another.

5. The adhesive splicing tape of claim 1 , the first and/or second splittable connecting elements each having a layer of a splittable material, said layer being coated on both sides with a pressure-sensitive adhesive.

6. The adhesive splicing tape of claim 1 , the first and/or the second splittable connecting element comprising two layers which are joined by means of laminating composition and which, on their side facing away from the laminating composition, have a first or second layer, respectively, of pressure-sensitive adhesive.

7. The adhesive splicing tape of claim 1 , the first and/or the second splittable connecting element comprising a layer which is joined to the first carrier by means of laminating composition.

8. The adhesive splicing tape of claim 1 , the first and/or second splittable connecting elements each being disposed by means of pressure-sensitive adhesive on the first carrier.

9. A wound roll of material in web form, comprising an adhesive splicing tape of claim 1 .

10. Method for flying splice of flat web material which has been wound to form rolls, said method comprising affixing a topmost flat web of a new roll to an underlying web with an adhesive tape according to claim 1 , said adhesive tape being equipped with at least one layer of a self-adhesive on a top face, and at least one layer of a self-adhesive on a bottom face, said method further comprising:

a) exposing a first part of the self-adhesive on the top face of the adhesive tape and adhering said first part beneath a first ply of a new roll of flat web material;

b) exposing the self-adhesive on the bottom face of the adhesive tape and adhering the adhesive tape on top of a second ply of said new roll;

c) exposing a second part of the self-adhesive on the top face of the adhesive tape;

d) placing the new roll thus equipped adjacent to an old, almost entirely unwound roll that requires replacement;

e) accelerating the new roll to substantially the same rotational speed as said old roll;

f) pressing the new roll against the old web so that the exposed second part of the self-adhesive on the top face of the adhesive tape adheres to the old web.

11. An adhesive splicing tape comprising a first carrier and

a first splittable connecting element having a left-hand (l) and a right-hand (r) bounding edge, at least one of these two edges (l, r) being nonrectilinear and having projections (V) which are rounded at their furthest projecting points (v), and also

a second splittable connecting element having a left-hand (L) and a right-hand (R) bounding edge, at least one of these two edges (L, R) being rectilinear, and the first and second splittable connecting elements being disposed adjacent one another on the first carrier, and also

a second carrier, and the first and second splittable connecting elements each joining the first carrier to the second carrier, the first carrier and the second carrier each having a layer of pressure-sensitive adhesive on their sides facing away from the connecting elements.

12. The adhesive splicing tape of claim 11 , the first and/or the second splittable connecting element comprising a layer which is joined to the first or second carrier by means of laminating composition.

13. The adhesive splicing tape of claim 11 , the first and/or second splittable connecting elements each being disposed by means of pressure-sensitive adhesive on the first and/or second carrier, respectively.

14. Method for flying splice of flat web material which has been wound to form rolls, said method comprising affixing a topmost flat web of a new roll to an underlying web with an adhesive tape according to claim 11 , said adhesive tape being equipped with at least one layer of a self-adhesive on a top face, and at least one layer of a self-adhesive on a bottom face, said method further comprising:

a) exposing a first part of the self-adhesive on the top face of the adhesive tape and adhering said first part beneath a first ply of a new roll of flat web material;

b) exposing the self-adhesive on the bottom face of the adhesive tape and adhering the adhesive tape on top of a second ply of said new roll;

c) exposing a second part of the self-adhesive on the top face of the adhesive tape;

d) placing the new roll thus equipped adjacent to an old, almost entirely unwound roll that requires replacement;

e) accelerating the new roll to substantially the same rotational speed as said old roll;

f) pressing the new roll against the old web so that the exposed second part of the self-adhesive on the top face of the adhesive tape adheres to the old web.
