Abstract
A high capacity envelope stacker accepts envelopes from a source in a planar configuration, pivots each envelope individually on either of its long edge axis so that it is stacked on its long edge, and then restrains the envelope on its two faces so that the stack of envelopes as a whole are stacked 1-N exactly as they arrive from the printer up to about 500 envelopes.
