description	Subject matter of the invention is an adhesive tape (K) for on-the-fly roll changeover of flat web material (RB) wound up into rolls (R; B), having a carrier layer (K3), which comprises a first surface (K31) and a second surface (K32) opposite the first surface (K31), a first layer of adhesive (K1), which is disposed indirectly or directly over at least part of the area on the first surface (K31) of the carrier layer (K3), a second layer of adhesive (K2), which is disposed on at least one areal region (FB) of the second surface (K32) of the carrier layer (K3), and at least one predetermined breakage area for the areal splitting of the adhesive tape (K), where the predetermined breakage area is configured such that the at least one areal region (FB) comprises a surface coating (K4), which is disposed between the carrier layer (K3) and the second layer of adhesive (K2), where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of adhesion of the surface coating (K4) to the carrier layer (K3), and/or where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of cohesion within the surface coating (K4), wherein the second layer of adhesive (K2) has a deactivated bonding region (K6) on a surface (K21) pointing in the carrier layer (K3) direction.
