ABSTRACT:
A method for cutting a vertical incision in a plastic cap for containers. The plastic cap includes a flat top, a casing emanating from the flat top, and a guarantee area provided in an edge zone of the casing. The guarantee area has at least one holding section on a surface of the guarantee area. The method includes the steps of mechanically gripping the cap at a specific position determined based on the at least one holding section, mechanically providing the cap with a horizontal incision extending in the circumferential direction of the casing at a predetermined position on a bottom edge of the casing to distinguish the guarantee area from a remaining portion of the casing of the cap, which horizontal incision cuts substantially through a wall of the casing, and mechanically cutting at least one vertical incision into a wall of the guarantee area at a predetermined distance from the at least one holding section, the vertical incision extending perpendicularly to the circumferential direction of the guarantee area.
