Abstract: Adhesive tape for the on-the-fly roll changeover of flat web material wound up into rolls, comprising a carrier layer having a first surface and a second surface, a first layer of adhesive on the side of the first surface over at least part of the area, and a second layer of adhesive on one or more areas of the second surface, wherein the adhesive tape has regions suitable for areal splitting, at least those areal regions of the second surface on which the second layer of adhesive is provided being surface coated, the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of adhesion of the surface coating to the carrier layer, and/or the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of cohesion within the surface coating.
