An apparatus for producing a container cap, said cap being formed of plastic and including a flat top, a casing emanating from said flat top, and a guarantee area provided in an edge zone of the casing, said guarantee area including at least one holding section on a surface thereof and at least one vertical incision extending over a height of the guarantee area, said apparatus comprising:
- a centering device which rotates and securely holds the cap in a fixed position based on a form characteristic provided on the casing in a fixed relationship to said at least one holding section, said centering device comprising an outside centering device having a tracing pin biased against, and rotatable around, the casing;
- and
- a vertical cutting device having a blade, the cutting device placed relative to said apparatus, said centering device moving relative thereto so as to bring the cap into engagement with the vertical cutting device so as to produce said at least one vertical incision into a wall of the guarantee area at a predetermined distance from the at least one holding section while said centering device rotates and securely holds the cap in said fixed position.
