Abstract
Machine and method for extracting the contents from envelopes for presentation to an operator. The envelopes are stacked at an input station and fed one at a time from the input station to a cutting station. At the cutting station, the envelopes are severed along their edge portions to provide access to the contents. From the cutting station, the envelopes are transported to a separating station, where the contents are separated from the envelopes. The contents from one envelope at a time are conveyed to a pick-up station for presentation to an operator at a work station. When the operator removes the contents of one envelope from the pick-up station, the contents of another envelope are conveyed to that station and presented to the operator. As each envelope leaves the separating station, it is checked to verify that the contents have been removed.
