Abstract
A drive for rotating an article such as a roller shaft or plate has a gear which is connected to the rotating article in a rotationally fixed manner. The gear has a number of teeth. A means for driving the gear has a movably mounted lever with a tip that meshes with the gear to have driving contact with the gear and impart driving motion to the gear. The tip forms a tooth and the gear teeth and the tooth of the lever tip are shaped to mesh with a rolling contact between them during the driving motion.
