Abstract
An apparatus for extracting contents from a plurality of envelopes comprises a device for severing edge portions of the envelopes and for discharging the edge-severed envelopes serially and one at a time, and a device for extracting the contents from the edge-severed envelopes including a pair of conveyor belts which diverge from a nip for receiving the edge-severed envelopes from the severing device, and vacuum ports cooperating with the conveyor belts to separate faces of the envelopes from one another, and a device for separating contents from the separated faces of the envelopes, for discharge from the apparatus. Also a device for receiving the separated contents and envelope faces, and for testing them to verify that only effectively extracted contents are passed on for further processing.
