Abstract
Inspection of completed cigarettes is accomplished by the cigarettes traveling on a rolling drum past a single stationary rolling block with preferably two cameras connected to a vision system. The first camera views the cigarette before the rolling block, the cigarette is then rolled approximately 180.degree. and then the second camera views the previously hidden portion of the cigarette. Cigarettes are accepted or rejected based on a comparison of the viewed cigarettes to a predetermined set of characteristics.
