Abstract (en)

[origin: WO8605220A1] The top wire of a Fourdrinier machine is converted into a negative mold for imparting a textured pattern of fiberboard. A positive mold (10) of the pattern (13) is covered with a resin precursor (16) to fill the depressed areas of the pattern. Upon partial curing, the resin forms convex menisci (15) above the depressed areas and the wire (17) is pressed onto the mold. The protruding resin is bonded to the wire when curing is completed. The negative of the pattern is thus transferred to the wire.
