Assessing the Slice in Terms of Turbulence Control and Sheet Quality, 2006 Papermaker's Conference

PressWeb.jpg

While the slice is less often used for fiber control, it remains part of many working paper machines. The issue ad-dressed in this study is whether the slice reduces the effectiveness of the headbox turbulence as flow passes onto the wire. Highly resolved Digital Particle Image Velocimetry measurements were made in a headbox model. Turbulence data and field experience indicate that removing the slice can significantly improve sheet quality. Specific physical mechanisms are provided.
