Abstract
A liquid metering system in the manufacture of paperboard includes a moisture applicator roll. The moisture applicator roll is configured to rotate about its axis generally perpendicular to a paperboard material flow stream. As the moisture applicator roll rotates, it has a tangential velocity. The tangential velocity is a percentage of the linear velocity of the paperboard material moving down the flow stream. The moisture applicator roll contacts the material at a contact location. At the contact location, the direction of the tangential velocity of the applicator roll opposes the direction of flow of the material. The percentage of the tangential velocity of the applicator roll relative to the linear velocity of the material is generally in a range from about 2% to about 160%.
