Abstract
In a walking beam type accumulating conveyor there is provided a transfer bar which moves in a rectangular motion, first upward, then longitudinally a distance corresponding to the distance between station, then down and then back longitudinally to the initial position. On the transfer bar are pivoted carriers, one for each station. The decision to lift a workpiece and transferred, is made during the elevation step of the cycle of movement based upon whether an empty station exists ahead of the workpiece. The decision is communicated between stations by rope or chain.
