b. Paper Folding
Paper is folded using paper fold rollers and a paper pushing plate.
Almost concurrently with the start of roller rotation, the paper pushing
Almost concurrently with the start of roller rotation, the paper pushing
plate starts operating to push the paper stack into the gap between the
paper fold rollers. When the paper stack is fed about 10 mm with the
rotation of the paper fold rollers, the paper pushing plate returns to the
rotation of the paper fold rollers, the paper pushing plate returns to the
home position. Then, the paper stack is delivered to the bind tray using
the paper fold rollers and bind delivery rollers.
Half the entire surface of each paper fold roller is uncovered excluding
Half the entire surface of each paper fold roller is uncovered excluding
the central area and the area at the left and right ends. The uncovered
surface of the upper paper fold roller comes in touch with the uncovered
surface of the lower paper fold roller only at the center and left and right
surface of the lower paper fold roller only at the center and left and right
ends, allowing a paper stack to be fed without causing creases. The
other half of the upper paper fold roller that is covered comes in touch
with the other half of the lower paper fold roller that is also covered,
with the other half of the lower paper fold roller that is also covered,
allowing a paper stack to be folded while being fed.
