ABSTRACT:
An apparatus for facilitating the extraction of the contents of envelopes includes a mail opening and extraction assembly which opens an envelope along at least one edge of the envelope and spreads apart the opened envelope to facilitate removal of the contents of the envelope. A power unit provides a source of electricity and fluid pressure, and a supply line couples the mail opening and extraction assembly to the power unit to transfer the electricity and fluid pressure to drive the mail opening and extraction assembly. The mail opening and extraction assembly includes a pivotable extraction surface having a first position substantially flush with a transfer surface and a second position in which the extraction surface is pivoted so as to be at an angle with respect to the transfer surface. The extraction station also includes a vacuum apparatus for spreading apart the envelope to expose the contents of the envelope. Specifically, a lower vacuum cup on the extraction surface contacts a first face of the envelope and an upper vacuum cup contacts a second face of the envelope. A vacuum arm extends from the vacuum cup and is movable in a direction away from the extraction surface to spread the envelope apart. The upper vacuum cup is rotatable about the axis of the vacuum arm so as to distort the envelope which is being spread apart to insure that the contents of the envelope do not cling to the inside surface of the envelope.
