<p>Dewatering arrangement adapted to use in a twin-wire dewatering section of a paper machine, comprising a rotating forming roll, a head box for supplying stock arranged before the forming roll, a closed loop first wire adapted to, be partly wrapped around the forming roll to a separation line where its contact with the forming roll ceases, and to receive the stock from the head box on its surface not facing the forming roll, a closed loop second wire adapted to be partly wrapped around the forming roll on top of the first wire thereby pressing the stock between itself and the first wire, a first blade, substantially parallel with the forming roll, is arranged to support the lower side of the wire after the separation line of the forming roll and is arranged such that the tip of the blade is directed against the wire transporting direction, The distance from the separation line to the blade is less than 100 mm. By supporting the wire close to the forming roll movement of the first wire is suppressed, thus reducing unwanted effects like sheet damages.</p> |
