Sheet with a weakness zone

Abstract

The subject of the application is a sheet with a weakened zone (1) formed by a plurality of cuts (2), or holes, made in the sheet material, which are arranged to form two cut lines (3) running parallel to each other, wherein all the cuts (2) of a given cut line (3) are identical and wherein the cuts (2) of one cut line (3) are shaped as mirror images of the cuts (2) of the other cut line (3), symmetrical with respect to the axis (a) of symmetry, wherein the axis (a) of symmetry is parallel to the direction (k) of the cut lines, characterized in that the cut (2) of a given cut line (3) is formed from three interconnected sections (4, 5, 6), respectively, one main section (4) and two arm sections (5, 6), wherein the main section (4) runs parallel to the direction (k) of the cut lines, and the arm sections (5, 6) extend from the main section (4), at an obtuse angle (á) to it and with respect to the direction (k) of the cut lines,and the second arm section (6) extends from the main section (4), from a point closer to the beginning of this main section (4), at an acute angle (â) to it and in relation to the direction (k) of the cut line.,
