<p>An incipient position of a meshing engagement where the distal ends of both threads contact is detected on the basis of the change in the acting force. A change in the force acting on the cap (5) is measured as distal ends of the threads on the cap and the vessel (2) contact each other during the relative rotation of both threads. An independent claim is also included for a capping apparatus.</p> |
