Cinta adhesiva y material de banda plana con dicha cinta adhesiva

The present invention relates to an adhesive tape (K) for replacing a flat web material (RB) wound on a roll (R, B) on a ply, comprising: a carrier layer (K3) having a first surface (K31) and a second surface (K32) opposite the first surface (K31); a first adhesive compound layer (K1) disposed on the first surface (K31) of the carrier layer (K3), and indirectly or directly on at least a portion of the surface; a second adhesive compound layer (K2) disposed indirectly on at least one side area of the second surface (K32) of the carrier layer (K3); and at least one predetermined breaking surface for dividing the adhesive tape (K) in a planar manner, wherein the predetermined breaking surface is configured as a part of a dividing system (K4) between the carrier layer (K3) and the second adhesive compound layer (K2). After being divided, a reinforcing layer (VS1) which increases the tearing force of such a part (K4b) of the dividing system (K4) remaining on the second adhesive compound layer (K2) in the longitudinal direction with respect to the advancing direction of the adhesive tape (K) is applied between the second adhesive compound layer (K2) and the dividing system (K4).
