The MultiPulse™ foil is designed to impart a series of high frequency pulses into the sheet.
The concept is based on the proven theory that the size of the fiber floc created in a sheet is proportional
to the scale of the stock activity generated. Finer scale stock activity results in smaller floc size.
The design of the blade allows for very high pulse frequencies (in excess of 120 Hz) to be achieved,
even at speeds below 1000 fpm.
The MultiPulse foil is also effective in redistributing fines in the sheet since it forces a portion of the water
removed by the foil back into the sheet. This prevents sealing, keeping the sheet open for easier water removal on
the fourdrinier table, in the press, and in the dryer section. Sheet strength properties are also increased with
improved fines distribution.
