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.

Abstract: The present invention comprises a dual tote sorting and stacking apparatus for continuously transporting, sorting and stacking sequentially fed sheets of paper such as from printing, copying and duplicating machinery. The apparatus employs mass airflow type of conveyors for paper transport. A diverter is provided for selectively diverting the sheet to designated receiving trays or, optionally, for expelling the sheet from the apparatus. A jogger is provided for jogging the sheets which are deposited into the trays into individually aligned job stacks. An assembly may also be provided for flipping the sheets as they enter the apparatus or for feeding individual sequentially fed sheets into the apparatus.
