Abstract
In accordance with the present invention apparatus for stacking flat articles, such as envelopes, on edge, comprises structure for transporting the envelopes on edge along a transport path and a deck plate having an upper side adjacent the transport path. A vertical registration wall, which is mounted on the deck plate, defines a stacking bin in which the envelopes are stacked. A deflector, which is situated between the transporting structure and the stacking bin, pivots between a first and second position, wherein the first position allows the envelopes to be transported past the stacking bin and the second position deflects the envelopes into the stacking bin. There is an urge roller, located in the stacking bin between the deflector and the registration wall for urging the envelopes towards the registration wall. There is a spring loaded paddle slidably positioned in the stacking bin orthogonal to the registration wall and above the deck surface, for urging the stacked envelopes toward the urge roller. The registration wall is positioned for a particular size envelope such that a trail edge length of the envelope is approximately 11/2 inches, the trail edge length being the dist…
