Non-contact article rotating apparatus

An non-contact article rotating device is disclosed that rotates articles without impacting or contacting the article other than the bottom of the article. The device is designed to accept a stream of articles with minimum gaps between them, and rotate only those that are programmed to be rotated. The device accepts any combination of rotated and non-rotated articles and can rotate them through angles up to and through 360 degrees. One embodiment of the disclosed device uses only one single-speed drive motor and pneumatic components to operate two conveyor roller sections. While one conveyor roller section maintains a constant speed, the conveyor rollers of the second conveyor roller section are sequentially braked and unbraked to rotate an article that is positioned partially on the first conveyor roller section and partially on the second conveyor roller section. The difference in speeds between the two conveyor sections rotates the article.
