The EdgeDeckle is used to control the edge on Fourdrinier wires with large lip openings. It prevents the stock suspension from bleeding at the sides and provides for cleanliness in the headbox.
The EdgeDeckle prevents the stock suspension from bleeding at the Fourdrinier wire edge by means of a sealing strip. The optimal distance between edge control and wire is set with simple adjustment mechanisms. The remaining gap between sealing strip and wire is sealed from the outside with a spray tube. Setting the sealing strips prevents stock ripples from forming. Mechanical adjustment of the format width can be done even while the machine is running. In order to prevent build-up of fibers on the EdgeDeckle, all surfaces are wetted with a film of water.
The EdgeDeckle is used at Fourdrinier wires with large lip openings. The edge control can be easily retrofitted on any headbox.
