Claim Text:
1. A method for using a splicing tape to equip a wound roll for flying splice, said method comprising the steps of: (a) providing a splicing tape comprising: a first carrier and a second carrier, at least two strips of a water-based laminating composition disposed between the first carrier and the second carrier, each strip of the at least two strips of the laminating composition directly contacting both the first carrier and the second carrier and thereby joining the first carrier to the second carrier, the first and second carriers each having, on a side remote from the at least two strips of the water-based laminating composition, a first layer and a second layer of a pressure-sensitive adhesive, and the first and second carriers each being continuous layers, wherein the at least two strips of laminating composition are not in direct contact with each other, the at least two strips of laminating composition are not in direct contact with any other strips of laminating composition in the splicing tape, and the at least two strips of laminating composition form a predetermined breakage point; (b) adhering the splicing tape to a roll in such a way that part of the first layer of pressure-sensitive adhesive forms a first bonding area with the end region of the uppermost ply of the wound roll, and the second layer of pressure-sensitive adhesive, in the transition region from uppermost to second-uppermost ply of the roll, forms a second bonding area to the roll, located partly below the first bonding area, where the first bonding area extends within the two longitudinal edges in the longitudinal direction of the splicing tape, and the part of the first layer of pressure-sensitive adhesive that does not form a bonding area with the end region of the uppermost ply of the wound roll is exposed for adhesive coupling to a fast-running web of another, unwinding roll.
