ABSTRACT:
A conveying system comprising an upfeed conveyor for conveying individual stock items upwardly to a press or the like and a generally horizontal infeed conveyor for conveying endwise a stack of items positioned on edge thereon to the upfeed conveyor which has several sections all of which are activated to move the item delivered thereto upwardly and wherein the lower sections are periodically stopped and the uppermost section is freely adapted to move to facilitate withdrawal of the item in transit from the upfeed conveyor, the infeed conveyor being vertically adjustable and tiltable with respect to the upfeed conveyor for handling different sized stock items, and wherein conveyors are so juxtaposed that the item in transit on the upfeed conveyor shields the upper portion of the next item from engaging movable section until the item in transit is completely withdrawn from the upfeed conveyor and wherein a retard is provided with an items gauge shield to insure single item feeding.
