WEB PATTERNING APPARATUS COMPRISING A FELT LAYER AND A PHOTOSENSITIVE RESIN LAYER

摘要

The invention comprises an apparatus (200) for use in making a web of papermaking fibers. The apparatus (200) comprising: a dewatering felt layer (220) having a first web facing felt surface (230) at a first elevation and a second oppositely facing felt surface (232) and a web patterning layer (250) comprising a photosensitive resin. The patterning layer (250) penetrates the first felt surface (230) and extends from the first felt surface to form a web contacting top surface (260) at a second elevation different from the first elevation. The invention also comprises a method of forming a web support apparatus having a felt layer and a web patterning layer.
