• Layering Fourdrinier headbox - Valmet

    OptiFlo Layering Fourdrinier tackles the boardmakers' challenges in combining lower basis weights, faster speeds and higher ash contents resulting from the increased use of recycled fiber. This novel solution provides excellent layer coverage, considerably lower residual variation in basis weight as well as excellent formation with no streaks or tiger stripes.
