The invention relates to an adhesive system for flying splice ("parting system"), suitable for producing an adhesive bond on a substrate that can be parted again in such a way that adhesive residues remain neither on the reverse (U K) of the adhesive tape (K) nor on the substrate in the region of the parted adhesive bond, at least the right boundary edge (r s) of the parting system (S) on the reverse (U K) of the adhesive tape being designed in the form of a line (F) that extends along a straight baseline (X) ("right line") and is characterized by a succession of rising (s) and falling (f) line sections, so that between each rising line section (s) falling line section (f) that follows it in a preferential direction (v), in the line region formed by these two line sections, a furthest--right point (E max) ("maximum") or a plurality of directly adjacent furthest-right points (B max) ("maximum region") is formed, and so that, between each falling line section (f) and a rising line section (s) that follows it in the preferential direction (v), in the line region formed by these two line sections, a furthest-left point (E min) ("minimum") or a plurality of directly adjacent furthest-left points (B min) ("minimum region") is formed, it being the case, for the plurality of the line regions (R) ("rightwardly projecting line region") formed by a respective rising line section (s), a respective subsequent maximum (E max) or a respective maximum region (B max) following in the preferential direction (v), and a respective falling line section (f) following again in the preferential direction (v), that the steepness in the rising line section (s) is lower than the steepness in the falling line section (f) that follows it in the preferential direction (v), the steepness (in the sense of this specification) of a line section denoting the amount of the slope of a straight line ("straight steepness line") through the two line points bounding the line section.
