Abstract
A three sided envelope opening and extraction apparatus and method are disclosed. The envelopes pass from a supply hopper to three envelope slicing devices which open three sides of the envelope and thereafter, the envelopes are disposed into a transport system for conveyance to the opening apparatus with the unopened edge positioned generally downwardly. The opening apparatus includes opposed elongate folder blades which close upon the side panels of the envelope approximately one third of the distance above the unopened edge thereof to clamp the envelope therebetween. An opposed pair of elongate grasping members including suction cups engage the opposed panels of the envelope above the folder blades and pull the opposed panels downwardly and tautly against the folder blades to provide a deformed and permanent crease in the envelope panels along the folder blade edges whereupon the folder blades and grasping members release the envelope panels and are withdrawn away from the envelope panels. An envelope transport is provided to convey the envelopes in time sequence into the envelope opening apparatus and thereafter from the envelope opening apparatus, following the opening operation thereof, into an envelope receiving track at which point the contents thereof are extracted and sorted.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
