摘要：
A conveyor having a retractable stop providing a nonsliding contact surface to the leading faces of conveyed articles to prevent damage to the faces of the articles. One version of such a stop has a contact surface defined by the peripheries of rollers that rotate on the accumulated articles as the stop moves from a blocking position accumulating articles on the conveyor to a retracted position releasing accumulated articles to advance downstream along the conveyor.
