MultiForm


MultiForm™


The MultiForm™ is the most flexible and cost effective stock activity generation control system on the market.

Most Flexible
A variety of different inserts can be used to produce the correct type of stock activity in the correct location of your forming process. The design of the inserts determines the stock pulse frequency along with how much water is introduced back into the sheet.
The inserts are also changeable on-the-run to accommodate different machine speeds and changes in fiber furnish.

Cost Effective
A UHMW polyethylene base board is designed to slide onto the existing t-bars on any existing drainage structure. As the inserts wear they are replaced at a cost much lower than traditional stock activity generating foil blades due to a minimal amount of material and simple design.
MultiForm
Delay drainage and generate stock activity.

How the Different Inserts Work

standard insert The Standard insert is the most powerful insert, this is because it has the longest pulse and a very abrupt trailing angle. The trailing angle also forces water back into the sheet. This insert is very beneficial for slower speeds and floccy air pad type headboxes. This insert is also targeted more for the forming board.
multipulse insert The MultiPulse™ insert produces a higher pulse frequency resulting in smaller eddy currents which complement a small fiber furnish and hydraulic headboxes. This insert also forces a small amount of water back into the sheet. It is suited for the forming board and gravity foil sections.
agitator insert The Agitator insert provides a gentler pulse than the Angle or MultiPulse inserts due to its gradual trailing angle. This insert also forces the least amount of water back into the sheet which is beneficial for later sections of the table where disrupting the wire side of the sheet may have negative effects.
