1. An adhesive tape for splicing together two material webs, comprising:
- a) a backing having first and second faces, first and second longitudinal edges, and first and second latitudinal edges;
b) a first adhesive layer on said first face, said first adhesive layer extending across a width of the backing from a first point at or near said first longitudinal edge towards a middle of said first face to a second point either i) at said second longitudinal edge or ii) between said first longitudinal edge and said second longitudinal edge;
c) a second adhesive layer on said first face, said second adhesive layer extending across the width of the backing from a third point between said first longitudinal edge and said second longitudinal edge towards said second longitudinal edge to a fourth point at or near said second longitudinal edge;
wherein the second point is located further from the first longitudinal edge than is said third point, so that the second adhesive layer overlaps the first adhesive layer.

-
a) a backing having first and second faces, first and second longitudinal edges, and first and second latitudinal edges; b) a first adhesive layer on said first face, said first adhesive layer extending across a width of the backing from a first point at or near said first longitudinal edge towards a middle of said first face to a second point either i) at said second longitudinal edge or ii) between said first longitudinal edge and said second longitudinal edge; c) a second adhesive layer on said first face, said second adhesive layer extending across the width of the backing from a third point between said first longitudinal edge and said second longitudinal edge towards said second longitudinal edge to a fourth point at or near said second longitudinal edge; wherein the second point is located further from the first longitudinal edge than is said third point, so that the second adhesive layer overlaps the first adhesive layer; and wherein the first adhesive layer is composed of a first adhesive and the second adhesive layer is composed of a second adhesive, and the first adhesive exhibits a higher shear resistance than the second adhesive, or the second adhesive exhibits a higher tack than the first adhesive, or a first bonding zone occupies at most only 30% of the width of the adhesive tape. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
