Abstract
The present invention comprises a paper sheet stacking and jogging apparatus for the semi-continuous stacking and jogging of individually fed sheets of paper from devices such as printing or duplicating machinery. A conveyor, comprising a pair of powered forward pinch rollers and a pair of powered rearward pinch rollers each having a plurality of driving tires, conveys the sheets within the apparatus. A beam strengthener, comprising two pairs of crowned and recessed tires, which are not driving tires, give the sheets beam strength as they are deposited to prevent jamming of the apparatus. A high-capacity, self-leveling tray assembly and elevating elevator receives the deposited sheets. A jogger selectively jogs the sheets which are deposited into the tray assembly into physically separated, distinct, aligned job stacks.
