ABSTRACT:
A method and apparatus are disclosed for accumulating sheets into a stack and for folding the stack with at least two folds into a "C" or "Z" letter fold. A continuously traveling conveyor travels past a plurality of sheet feeding stations. A sheet is removed from each station simultaneously and these sheets are transferred to a position over the conveyor, and they are stacked directly onto the previously deposited sheets on the conveyor so that simultaneously a sheet is added to each stack at a location opposite each station. Such stack is conveyed to a folding knife which folds the stack off center and leaves a larger unfold portion. At a second folding station, a folding device folds a second fold parallel to the first fold to complete a letter fold for the entire stack of sheets which folded stack is then discharged.
