ABSTRACT:
An extraction apparatus for the automated processing of bulk mail includes a first pair of rollers forming a nip for receiving each of a plurality of envelopes, with their contents. The envelopes, which have been opened along plural contiguous edges, are then passed to a second pair of rollers following the first pair of rollers, for receiving the opened envelopes (with the contents) from the first pair of rollers. The second pair of rollers are spaced from one another and each include a suction cup for engaging faces of the opened envelope responsive to an applied vacuum, and for spreading the faces of the envelope apart. A third pair of rollers following the second pair of rollers forms a nip for receiving the contents from between the second pair of rollers, thereby removing the contents from the envelope.
