<p>The cover sheet (1) is folded at least twice in its longitudinal direction in a zig-zag fashion. Thus with the formation of at least two folds, at least three strips (7,8,9) are produced located one on top of the other. An adhesive coating (21) is provided on at least one strip surface, in order that in the delivery form at least one fold is glued together over a large surface. The adhesive coating comprises a number of individual, adjacently located adhesion points, which are evenly distributed.</p> |
