ApplicationsGravity foil assemblies are an important component of fourdriniers. They are used to create activity pulses and begin early drainage on the table. The magnitude of the pulses is determined by machine speed, stock consistency, blade angle, width, and spacing. FeaturesRobust design and 316L stainless steel fabricationOptimal blades shape and spacingMultiple options for polyethylene and ceramic bladesOpen area matched to grade and speedBenefitsControlled pulse activityImproved sheet formationMinimal drag load impactOptimized drainage rateKadant provides a variety of engineered blade shapes for your fourdrinier depending upon grade, speed, furnish, and forming goals. We also provide multiple options for polyethylene and ceramic formulations customized for your specific needs.
