Abstract
A method for quantitatively dividing a zigzag folded sheet of paper comprises continuously folding a sheet of paper to obtain a zigzag folded sheet of paper having a plurality of divisions connected to one another, continuously accumulating the divisions one on top of another, allowing a separator with a cutting edge to be inserted, when the continuous accumulation constitutes a first unit composed of a prescribed number of divisions, between the uppermost division of the first unit and the division connected to the uppermost division and becoming the lowermost division of a second unit to be subsequently obtained, thereby partitioning the first unit, allowing the first unit and the separator to descend to accumulate the divisions which will constitute the subsequent unit on the separator and allow the separator to advance immediately before the fold between the aforementioned uppermost and lowermost divisions, and allowing the cutting edge to advance away from the separator to cut off the fold.
