Hydrofoils or "Foils"

On a Fourdrinier paper machine the foils are placed under the forming fabric. Their shape is designed to create suction as the foil and wet web pass over the surface. Hydrofoils also create a brief pressure pulse as the fabric passes over the leading edge. The alternating pressure and vacuum of a series of hydrofoils tends to move fibers around ...

Papermaking PAPERMACHINE – DRYING Introduction

Paper machine dryers have been modelled using computers and rigorous application of heat and mass transfer principles. However, there is often a need for some simple estimates of dryer sections of paper machines. In this case, data compiled from industry averages are frequently used.
