An article transporting conveyor having live rollers driven through power transmission rollers having a slip or non-slip connection with the live rollers in which the presence of the weight of articles to be conveyed increases the drive between the transmission rollers and the live rollers, but if the conveyor should experience a line blockage the transmission rollers would continue to function while the live rollers would slow and stop turning, thereby protecting the articles from damage and assuring minimum pressure on the articles from the drive transmission rollers.
