The container in which the stack of sheets is placed prior to entering the machine is equipped with an aperture in its lower surface through which sheets are removed individually by a rotating suction roller. A number of fingers are pivoted so that they may be swung into the aperture to push the stack of sheets away from the path of the suction roller so that the roller fails to pick up a sheet, thus inhibiting the sheet take-up process.
