Abstract
The present invention relates to a splicing tape (1) for continuous roll change, the splicing tape comprising: a) a first tape component including a first backing layer (2) and a first adhesive layer (3) on a first surface of the first backing layer (2); b) a second tape component including a second backing layer (4) and a second adhesive layer (5) on a first surface of the second backing layer (4); and c) a splitting layer (6) joining the first backing layer (2) and the second backing layer (4) together, such that the first and second adhesive layers (3,5) are facing away from the splitting layer (6), wherein the splitting layer (6) comprises a continuous and uninterrupted middle area (7) extending in the longitudinal direction of the splicing tape (1) and provided with repeating tapered protrusions (2) with flattened tips projecting from the middle area (7) towards both longitudinal edges of the splicing tape and to a method for manufacturing and using such a splicing tape.
