<p>Adhesive binding method comprises carrying out a perforating process on the folding edge so that two interrupted perforation lines are punched, in which the perforation lines are parallel at a short distance from one another and offset in the longitudinal direction, and forming a widened folding edge. The punch locations of both perforation lines are offset by the length of one perforating tooth along the folding edge. An independent claim is also included for a device for carrying out the method comprising perforating knives with cutting edges (6, 6', 6'') arranged in the direction of two parallel perforating lines (12, 13). The knives are displaced in the direction of their longitudinal axes about a perforating tooth.</p> |
