摘要： 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.

摘要： Operations associated with the reciprocating suction arms of a mail extraction device are modified to prevent bleed through from occurring as the opposing faces of an envelope are spread open by the reciprocating arms by drawing an air flow through the suction arms which is sufficient to draw the envelope faces to the suction arms without necessitating their contact with the envelope, and each other. This may be achieved using a vacuum pump of increased output, or by developing a burst in air flow drawn by the suction arms, at an appropriate point just prior to their closure.

摘要： An apparatus for the automated processing of bulk mail in a continuous and automatic procedure includes an operative combination of processing stations including an input station for receiving incoming mail in bulk fashion and for separting the pieces of mail for individual delivery to the remainder of the apparatus; a station for detecting irregularities in the contents of the envelopes, such as metal items, folded contents, or oversized items; a station for out-sorting envelopes rejected in accordance with the determinations made at the detection station; a station for opening the envelopes, preferably along multiple edges; a station for removing the contents from the opened envelopes, for subsequent processing of the contents; and a series of stations for handling and orienting the contents for subsequent delivery to a plurality of output stackers.
