Envelope sheet and method of processing

An envelope sheet for being automatically fed from a stack and printed by a laser printer and then automatically formed into an envelope having the appearance of a standard #10 envelope, said envelope sheet comprising:

• a front panel having a first upper surface and a first lower surface;
• a back panel connected to said front panel along a bottom fold line and having a second upper surface, a second lower surface, a bottom edge, a first left-side edge, a first right-side edge, a first adhesive area on said second upper surface adjacent said first left-side edge, a second adhesive area on said second upper surface adjacent said first right-side edge, and a third adhesive area on said second lower surface adjacent said bottom edge, said front and back panel having dimensions corresponding to a standard #10 envelope;
• a closing flap connected to said front panel along a top fold line and having a third upper surface, a third lower surface and a top edge, with a fourth adhesive area on said third upper surface adjacent said top edge;
• a first left-side flap connected to said front panel along a first left-side fold line and having a fourth upper surface, a fourth lower surface and a fifth adhesive area on said fourth lower surface;
• a first right-side flap connected to said front panel along a first right-side fold line and having a fifth upper surface, a fifth lower surface and a sixth adhesive area on said fifth lower surface;
• a second left-side flap connected to said first left-side flap along a left-side bottom fold line and connected to said back panel along a second left-side fold line, said second left-side flap having a sixth upper surface and a sixth lower surface, a seventh adhesive area on said sixth lower surface and an eighth adhesive area on said sixth upper surface;
• a second right-side flap connected to said first right-side flap along a right-side bottom fold line and connected to said back panel along a second right-side fold line, said second right-side flap having a seventh upper surface and a seventh lower surface, a ninth adhesive area on said seventh lower surface and a tenth adhesive area on said seventh upper surface;
• and
• a pressure sensitive self-stick adhesive which is substantially non-adherent to a laser printer fuser roll and not prone to causing blocking, said adhesive being adhered in a pattern to said first, second, fifth, sixth, seventh, eighth, ninth and tenth adhesive areas such that when a plurality of said envelope sheet are stacked, the stack has a sufficiently uniform height to allow sheets to be automatically fed therefrom, and such that when said envelope sheet is formed into an envelope, said first and eighth adhesive areas overlap and adhere said back panel and said second left-side flap, said second and tenth adhesive areas overlap and adhere said back panel and said second right-side flap, said fifth and seventh adhesive areas overlap and adhere said first and second left-side flaps, and said sixth and ninth adhesive areas overlap and adhere said first and second right-side flaps.
