Title: Automated envelope opener

Abstract: An automated envelope opener receives a stack of unopened envelopes of varying sizes, types and shapes, and feeds these envelopes individually to a cutting station. An edge of each envelope is automatically aligned with a reference surface, whereby each such aligned envelope edge can be cut at the cutting station by a rotating multi-toothed cutter and stationary anvil which are also aligned with the reference surface. In a preferred embodiment, means are additionally provided for shingling and stacking the envelopes after they have been cut open.
