Abstract
A high capacity envelope stacker accepts envelopes from a source in a planar configuration, pivots each envelope individually on either of its long edge axis so that it is stacked on its long edge, and then restrains the envelope on its two faces so that the stack of envelopes as a whole are stacked 1-N exactly as they arrive from the printer up to about 500 envelopes.
Claims10
An envelope stacker apparatus, comprising:
- a catch tray with said catch tray being divided into a receiving compartment for receiving envelopes flap side unexposed, individually from a source and supporting each envelope in a first substantially non-vertical position and a storage compartment for storing the envelopes in a stack in a second vertical position with the last envelope in the stack having its flap side exposed;
- said catch tray being positioned orthogonal to said source in order to receive each envelope short edge dimension first;
- and wherein said receiving compartment includes means for moving each envelope individually from said first position to said vertical position long edge dimension first.
An envelope stacker apparatus, comprising:
- a catch tray;
- means dividing said catch tray into a receiving compartment and a storage compartment, said receiving compartment being adapted to receive envelopes short edge dimension first and said storage compartment being adapted to receive envelopes long edge dimension first;
- and
- means for individually and separately converting envelopes after each envelope is received in said receiving compartment from an initial horizontal position to a substantially vertical position and individually stacking them in said storage compartment and forming a stack of 1-N envelopes.

A printer adapted to print images onto envelopes, comprising:
- an imaging apparatus;
- an envelope feeder adapted to feed envelopes after they have been imaged by said imaging apparatus;
- and
- a catch tray positioned orthogonal to said printer and adapted to receive each envelope short edge dimension first from said feeder with said catch tray being divided into a receiving compartment for receiving envelopes from said imaging apparatus short edge dimension first and supporting them in a first substantially non-vertical position and a storage compartment for storing the envelopes in a stack in a second substantially vertical position;
- and wherein said receiving compartment includes means for moving the envelopes long edge dimension first from said first position with a flap side of each envelope being unexposed to said vertical position wherein said flap side of the last envelope in the stack is exposed.
