By setting the position of the EdgeMaster in machine direction, it can be optimally adapted to the shape of the flow. Positioning screws allow precise lifting, lowering and pivoting. Water flushing prevents the suspension from flowing under the edge control device. In addition, spray water nozzles continuously moisten the surfaces in contact with the stock, enabling trouble-free production.
The EdgeMaster is retrofitted with an adapter plate extension to the existing headbox or by supplying a new format plate.
EdgeMaster is used at headboxes for Fourdrinier wire and hybrid former paper machines. These devices are frequently combined with wire edge lifters (EdgeCurlers).

The EdgeCurler’s rugged, ceramic, contoured material prevents wire abrasion and ensures a long service life. To prevent the stock suspension from bleeding at the paper web edge on the Fourdrinier wire, an EdgeMaster or EdgeDeckle is combined with the EdgeCurler. Thanks to the easy adjustment of the wire edge lifter, the profile can be very easily adjusted manually, depending on the requirements. In addition, there is no impediment when changing the wire.
EdgeCurler is used at the Fourdrinier wire and prevents bleeding of the stock suspension at the paper web edge.

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.

Fibers and fillers carried along on the wire edge are sprayed off by the EdgeCleaner nozzles and collected in the whitewater pan. Since fibers of different plies are not mixed with one another, returning the raw materials to the short cycle saves valuable fresh fibers. All settings of the fan-type nozzles are fixed with adjusting screws. When changing the wire, EdgeCleaner can be pivoted away via a pivot point so as not to interfere with the changing of the wire. The fan-type nozzles and return funnel are kept moist by spray nozzles to prevent fiber build-up.
EdgeCleaner is used in Fourdrinier or top wires for cleaning the wire edges.
