Abstract

Paper making machine hydrofoil made of stainless steel or polyethylene or having the wire mesh screen contacting faces lined with ceramic materials has an acute leading edge portion formed by an inclined depending wall and a horizontally extending screen supporting surface from extends in the direction of web movement a concave surface which may be circular, parabolic or hyperbolic, the configuration of the hydrofoil leading to a 30% reduction in the driving resistance and a 15% increase in water extraction.
