Technology Task of SpeedSizer Increase strength Improve surface properties Task of SpeedSizer Application Principle Coating Technologies Film coating Coat structure of a film coater Operating windowProfiled and smooth rods Pre-metering Smooth rod How to Achieve Sufficient Penetration? Increased roll diameter for longer dwell time Higher line load up to 80 kN/m - Limitation: Sheet crushing Softer roll covers - Limitations: Nip deformation and heat dissipation Better penetration due to reduced starch viscosity How to Achieve Sufficient Penetration? Longer dwell time: Increased roll diameter Softer roll covers Limitations: Nip deformation and heat dissipation Higher line load up to 60 kN/m no significant improvement above 60 kN/m Above 80 kN/m: Sheet crushing possible Better penetration due to reduced starch viscosity Nip transfer (Video) Challenges to Produce Low Basis Weightsat High Speed Levels Liquid application limited by moisture and wet strength Higher strength properties to be controlled by starch type and consistency Penetration to be optimized by roll diameter and line load Free open draws reduced to minimum, sheet tension adjusted to moisture and wet strength SpeedSizerWeb release and wrapping angle Web releaseHow to adjust release to base paper properties? 4 Components Components 4.1 Overview 4.2 Applicator rolls 4.3 Framing 4.4 Application sy
