In a machine for working (or processing) a continuous sheet while the continuous sheet travels through the machine, an intermittent feeding apparatus for the continuous sheet is provided which has a suction roll disposed on the downstream side of the working (or processing) section for sucking and transporting the continuous sheet, adjusting means for adjusting a sheet sucking and transporting period of the suction roll, and a secution box disposed on the upstream side of the working (or processing) section for continuously exerting upon the continuous sheet a suction force that is weaker than the suction force exerted by the suction roll.
