<p><P>PROBLEM TO BE SOLVED: To provide a papermaking device by which the thickness of obtained paper can return to the same level as the thickness of paper obtained before operation stop quickly after the operation restarting even when a pump for transferring a pulp suspension to a headbox stops temporarily. <P>SOLUTION: In a paper device, when a pump 110 in the middle of transferring a pulp suspension stops temporarily and then restarts, a control section changes the transfer direction of the pulp suspension by the pump 110 to the opposite direction G. Thus the pulp suspension stored in a storage section 36 is caused to flow back to the inside of a piping 93 from an inflow section 50, after which the pulp suspension is transferred in the normal direction F, and the pulp suspension flowed back to the inside of the piping 93 is controlled so as to flow into the storage section 36 again. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
