<p><P>PROBLEM TO BE SOLVED: To resolve the problem that the reduction in amount of water borne on one of a pair of rollers, to which water is supplied from the other, makes the water content in a thickness direction of a sheet non-uniform to bring about bending of sheet called warp, when performing humidification of adding water to the sheet by using the pair of rollers. <P>SOLUTION: The amount of water borne on the roller having the water content varied is calculated as an estimated water amount by operation, and sheet intervals are widened when a difference between the estimated water amount and a threshold exceeds a threshold. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
