ABSTRACT:
Apparatus for stacking a web of continuous prefolded paper forms includes a compacting mechanism having a plurality of elongate rigid compacting finger elements vertically suspended in pairs and freely pivotable from a horizontal rotating crankshaft located above and along one side of a paper stack. The finger elements which have a roughened active surface are vertically reciprocated by the crankshaft so that their active surface slidingly engages the topmost fold or edge of the stack during downward movement but disengages the stack during upward movement.
