ABSTRACT:
An apparatus for sequentially folding paper includes a first pair of rollers which feeds the paper to a first uncovered concave buckling chute. A paper stop mechanism aligns an end of the paper in a gap between the chute and a second pair of rollers which in turn receives the document to form a first fold in the paper. The second roller pair conveys the paper to a second uncovered curved chute which coacts wih a third pair of rollers to form a second fold in the paper. Use of uncovered buckle chute facilitates clearance of paper jams without requiring disassembly of the apparatus.
