Vibrating foil improves paper properties.
This article describes a vibrating foil that improves drainage, formation, cross-direction profile and sheet structure, according to the manufacturer. The Vibre-FoilTM imparts a cycling energy pulse to the partially formed sheet to fluidize the fiber slurry. For a brief instant, the energy pulse causes the fiber suspension to behave as if it was at a much lower consistency. This allows individual fiber to flow and change orientation to fill in lower basis weight areas of the sheet. The result is a squarer sheet with a more uniform CD basis weight and sheet structure profile.OCTOBER 2003
