"GROOVED AND PERFORATED LAYER FOR USE IN PAPERMAKERS' FABRIC"
Application 259/DELNP/2006 published 2007-08-17, filed 2006-01-13
A grooved perforated layer for use in a papermakers' fabric is provided. The grooves serve to diffuse flow at the surface of the perforated layer so as to reduce the pressure drop across the layer and thereby reduce the migration of fines. In this manner, the light/dark pattern associated with the fines is avoided and the quality of the resulting paper sheet is improved.
