ABSTRACT:
A paper folding machine comprises a slitter for longitudinally slitting a web of printed paper into two halves, a pair of triangular plates for longitudinally folding slitted halves of the web, a cutting drum for transversely cutting the folded halves into sheets of papers, an overlapping drum, a belt conveyor for conveying the sheets of printed papers from the cutting drum to the overlapping drum and for clamping the sheets between the overlapping drum and the belt conveyor, a gripping drum which receives the sheets from the overlapping drum and folds the sheets, and a delivery drum which receives the sheets from the overlapping drum and delivers the sheet to a stacking station. The gripping drum and the delivery drum are selectively operated depending upon whether sheets or sections of printed papers are delivered.
