Abstract
The present invention provides new offsetting paper stacking devices and methods which automatically stack sheets of paper into groups which are offset from each other. The offsetting paper stacker stacks sheets of paper that are feed into an input end of the device one at a time at a high rate of speed. The paper is stacked in one pile, however, within that pile there are groups of sheets that are stacked at a sideways offset to the group immediately above and below. Accordingly, every other group of sheets of paper will be in line with each other and each adjacent group will be offset from each other. The offsetting paper stacker includes stacker wheels which are rotatable about two axes of rotation to stack the paper in an offset manner.
