Abstract
A method and apparatus are disclosed that allow items to be placed on a stack of items in a manner that minimizes interference with the existing stack. Further, a method and apparatus are disclosed for stacking items such that marking of the items is minimized while the item is stacked. In some embodiments, the method and apparatus may include employing a plurality of forks, where a first fork in the plurality includes a belt that rotates at least partially within a tapered housing of the fork. In some embodiments, the plurality of forks is vertically movable, and the method and apparatus may include a squaring mechanism that is separate from the plurality of forks. The overall throughput of the method and apparatus may be increased by employing this independent squaring mechanism.
