Abstract
Movement of the case conveyor is terminated with the leading flap aligned with a flap engaging element mounted above the case on the end shaft. The shaft is rotated to cause the element to engage and partially open the leading flap. The shaft is supported by a carriage which is movable along a track extending in the direction of conveyor movement. As the element reaches its final rotational position, movement of the carriage along the track is initiated, causing the element to pivot the leading flap to the open position. Movement of the conveyor is then resumed as the carriage returns to its initial position. The rotational and translational movements of the element are independently actuatable and adjustable.
