Claim 10:
11. An apparatus for producing a cutting geometry running in the circumferential direction in a shell of a closure cap for a container, said apparatus comprising:
a) a transport installation for transporting the closure cap along a transport path which comprises a machining section;
b) a stationary cutting knife having a cutting blade which for generating the cutting geometry in the shell of the closure cap extends along a cutting section is present in the machining section,
wherein the transport installation comprises a driver which rotates about a rotation axis and is able to be brought to engage with a detent configured on the closure cap and is controllable to have, when the closure cap enters the machining section, a rotary position corresponding to a predefinable orientation of the closure cap about a central axis thereof,
c) a control apparatus designed and configured for controlling the rotating movement of the rotating driver and/or of the closure cap in the machining section to provide an angular velocity of the rotating driver about the rotation axis thereof is being lower than the angular velocity of the closure cap.
