Patent ID: 6925897

Claim:
A method of checking the fitting of a threaded cap onto a container by means of automatic cap-fitting apparatus of the carousel type, including rotatable support means which can move at least one container about a principal axis of the apparatus and at least one screwing head for screwing a cap onto a respective container so as to close the container as a result of its movement about the principal axis, each screwing head being arranged to screw a cap onto a container with a predetermined tightening torque, the method comprising the steps of: defining a predetermined angular interval of the movement of the at least one container about the principal axis of the apparatus within which the screwing of a cap onto the respective container with the predetermined tightening torque should be achieved, checking whether the predetermined tightening torque of a cap has been reached within the predetermined angular interval, and assuming that a container has been closed correctly if the predetermined tightening torque of the respective cap has been reached within the predetermined angular interval.
