Abstract
A power stacker provides for receiving lengthwise orientated envelopes projected longitudinally onto the power stacker at a receiving end of the power stacker from an envelope feed device. The power stacker has a base supporting both an elongated deck and registration wall, an envelope transport system for transporting envelopes along the deck from the receiving end to a stack end of the deck. The transport system includes a plurality of friction belts extending partly along the deck and a power stack wheel pivotally mounted to the registration wall. An upper deflection flap at having one end pivotally mounted to the registration wall at the receiving end of the deck at a vertical elevation above that of the longitudinal feed level of the feed device, the upper deflection flap to contact the deck at it other end at a predetermined nominal angle forward of the power stack wheel. A deflector ramp is fixably mounted to a lateral positioning member, the deflector ramp being horizontally elongated and set at a fixed inclining horizontal angle nominally set at 20 degree. The lateral positioning member is adjustably mounted to the deck and the deflector fixably mounted thereto for selecti…
