<p>The present invention comprises a paper sheet stacking and jogging apparatus. When handling high volumes of sheets at high speeds it is difficult to prevent jamming and misalignment when forming defined job stacks and collating. In order to assist in forming job stacks while minimizing jamming a conveying means (36), comprising a pair of powered forward rollers and a pair of powered rearward pinch rollers each having a plurality of driving tires (54), conveys the sheets within the apparatus. A beam strengthening means (38), comprising two pairs of crowned and recessed tires (68, 70) give the sheets beam strength as they are deposited to prevent jamming. A high capacity, self-leveling tray assembly (40) and elevating means receives the deposited sheets. A jogging means (42) selectively jogs the sheets which are deposited into the tray assembly into physically separated aligned job stacks.</p> |
