Abstract
A process for making relatively thick foraminous members the foramina of which form a preselected pattern. The backing film such as a thermoplastic film is placed in contact with a rotating drum. A foraminous woven element about which the foraminous member will be constructed is placed in contact with the thermoplastic backing film. Liquid photosensitive resin is supplied to a controlled thickness. A mask comprising the preselected pattern is placed adjacent the photosensitive resin and the resin is exposed through the mask to the light of an activating wavelength. Uncured resin is washed from the composite leaving behind the completed foraminous member.
