An adjustable blade apparatus including an operative surface which cooperates with a forming wire of a forming section. The apparatus includes a stationary support which extends in a cross machine direction relative to the forming wire. The support defines a guide rail having a front and a back end. The front end is disposed at a different elevation relative to the back end. The arrangement is such that the guide rail slopes in a cross machine direction. A blade defines the operative surface and the blade cooperates with the guide rail such that the blade is adjustably supported by the support. The arrangement is such that relative cross machine directional movement between the guide rail and the blade adjust the elevation of the operative surface relative to the wire.
