Patent 7222569 was granted and assigned to Komori on May, 2007 by the United States Patent and Trademark Office.
An oscillation amount adjusting device for an oscillating roller has a sleeve detent plate for restraining the rotation of a sleeve. An operator manually loosens a sleeve locking bolt to render the sleeve rotatable relative to a rotating shaft supporting the sleeve. The rotation of the sleeve is restrained by the sleeve detent plate. In this state, the rotating shaft supporting the sleeve is rotated by an oscillation drive motor to adjust the oscillation amount of oscillating rollers.
