摘要:
ON A PAPER MACHINE WHEREIN THE DRIERS ARE OPERATING AT FULL CAPACITY, THE MOISTURE CONTENT OF THE PAPER WEB COMING OFF OF THE MACHINE IS MEASURED. IF THE MOISTURE CONTENT SO MEASURED DEVIATES FROM THE DESIRED MOISTURE CONTENT, CORRECTIVE ACTION IS TAKEN THROUGH READJUSTMENT OF THE BONE DRY BASIS WEIGHT. FLOW RATE OF STOCK TO A PAPER MACHINE HEADBOX IS INCREASED WHEN THE MOISTURE CONTENT IS LOWER THAN THE DESIRED MOISTURE CONTENT AND THE FLOW RATE OF STOCK TO THE HEADBOX IS DECREASED WHEN THE MOISTURE CONTENT IS HIGHER THAN THE DESIRED MOISTURE CONTENT.
