- 18 - Abstract The present invention provides a machine and method wherein envelopes are removed from a supply hopper, one by one, and then transmitted to a plurality of sequen- tially disposed cutting stations wherein one end edge of the envelope is first severed, and thereafter an adja- cent side edge of the envelope is severed. The envelope with two adjacent edges thus severed is transmitted to a processing station at which the envelope is opened and held open by suction cups, for removal of contents by an operator. The envelope is thereafter transmitted to a detector station to confirm content removal and then to a recovery station, and then to a point of discharge. Means is provided for adjusting the opening of the suc- tion cups at the processing station, and stop means is provided for positioning the envelope as it reaches the processing station. The envelope is transmitted toward the processing station in horizontal disposition, and in one form of the invention at the processing station it is repositioned into angular disposition prior to the gripping action of the suction cups.
