Air-operated paper machine headbox

The Air cushioned rectifier roll jet headbox of Scan Machineries combines the highest paper quality with low energy costs. Two evenor rolls for deflocculating are used in the air padded pressurized headbox. Paper quality is improved and at the same time allows substantial savings in energy cost for our customers. Precise cross profiles of grammage (CD profile) are maintained and fiber orientation is ensured. All internal surfaces in contact with the stock flow are finely polished. Turbulence generators are combined with tube banks and nozzles for efficient operation and excellent runnability. The slice lips are motorized to adjust the slice gap between the lips and for controlling the output of stock flow.
