Abstract

In a printing/copier system which is delivering copies at a higher rate than the capability of the finisher, (i-e., stapler, binder, etc.) there is a need for a sheet buffering (holding back) device. One such device (as shown in the Figure) is a servo driven (2 speed) roll set and a high speed vacuum transport. The buffering concept includes having the servo roll set operating at a low speed (selected by sheet overlap and incoming sheet speed) during the buffering period. When buffering is no longer required (binding process complete) the servo roils will come up to process speed while driving the shingled slug onto a high speed (2X)
