<p>The present invention relates to an apparatus for guiding the wires of a paper machine former. The former comprises a double wire section including two wires (1, 2) in parallel direction (R) in which on the other side of the wires (1, 2) a dewatering unit (10) is arranged to drain water from the stock (3) flowing between the wires and in which at least the farthest wire (2) with respect to the dewatering unit is compressed with guide beams (20) or equivalent support members against the wire (1) nearest to the dewatering unit (10) in cross-machine direction with respect to wire direction (R) and across the web width . The load of these guide beams (20) is achieved by separate pressurized load hose construction (21) arranged between each guide beam (20) and support table or equivalent in order to achieve the desired press to the stock (3) between the wires (1, 2). Each load hose construction (21) is, according to the invention, equipped with separate pressure spaces into which a desired overpressure can individually be conducted to achieve a desired guide beam load against the wire leaning against the said guide beam across the web width.</p> |
