ABSTRACT:
An apparatus for converting rolls of paper web into stacks of folded sheets on a continuous high speed basis includes slitting a supply roll into plural narrow webs, folding the narrow webs longitudinally, cutting the folded webs transversely into sheets of suitable length, pre-stacking continuous streams of adjacent folded sheets emerging from the cutters before they are carried to a final stacking mechanism. The pre-stacking mechanism removes certain sheets from their original positions in the continuous streams of folded sheets and places them on top of other sheets in the streams from which they were removed in order to deliver to the final stacking mechanism sets of pre-stacked sheets with a gap between adjacent sets.
