Abstract

Abstract Foraminous members useful in making paper webs. The foraminous member of this invention has a macroscopically monoplanar, patterned, continuous network surface which serves to define within the member a plurality of discrete, isolated, deflection conduits. A foraminous woven element, such as a screen, is thoroughly coated with liquid photosensitive resin to a controlled depth above the upper surface of the woven element. A mask or a negative having opaque and transparent regions which define the pattern is brought into contact with the surface of the liquid photosensitive resin and the resin is exposed to light of an activating wavelength through the mask. The resin exposed to the activating light is hardened (cured). Uncured resin is removed from the composite leaving behind the woven element with the solid network formed by the cured resin.
