Abstract
Conveyor apparatus comprises a series of spaced rollers defining thereover a travel path for articles and an article stop located adjacent and downstream with respect to one of the rollers and movable between an extended position and a retracted position. In its extended position, the article stop extends into the travel path to obstruct passage of articles from the roller, and in its retracted position the article stop is spaced from the travel path to permit passage of articles from the roller. A roller stop is secured to the article stop and movable therewith, the roller stop being operatively disengaged from the roller when the article stop is in the retracted position and operatively engaged with the roller when the article stop is in the extended position. Operative engagement of the roller stop with the roller inhibits rotation of the roller and thus reduces the momentum with which an article engages the article stop.
