Patent ID: 8287973

Claim:
Adhesive system for flying splice (â€œparting systemâ€), 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 of the adhesive tape nor on the substrate in the region of the parted adhesive bond, at least the right boundary edge of the parting system on the reverse of the adhesive tape being designed in the form of a line that extends along a straight baseline (â€œright lineâ€) and is characterized by a succession of rising and falling line sections, so that between each rising line section and falling line section that follows it in a preferential direction, in the line region formed by these two line sections, a furthest-right point (â€œmaximumâ€) or a plurality of directly adjacent furthest-right points (â€œmaximum regionâ€) is formed, and so that, between each falling line section and rising line section that follows it in the preferential direction, in the line region formed by these two line sections, a furthest-left point (â€œminimumâ€) or a plurality of directly adjacent furthest-left points (â€œminimum regionâ€) is formed, it being the case, for the majority of the line regions (â€œrightwardly projecting line regionâ€) formed by a respective rising line section, a respective subsequent maximum or a respective maximum region following in the preferential direction, and a respective falling line section following again in the preferential direction, that the steepness in the rising line section is lower than the steepness in the falling line section that follows it in the preferential direction, the steepness of a line section denoting the amount of the slope of a straight line (â€œstraight steepness lineâ€) through the two line points bounding the line section.
