Abstract (en)

[origin: EP0867559A2] The apparatus to clean a fourdrinier or blanket (2), in a papermaking machine, has a jet (7) with a rotation speed of 2500-4000 rpm for a normal cleaning action, and a speed of 1000-2500 rpm to give an intensive cleaning action on the blanket (2). Preferably the jet (7) is pitched at an angle ( alpha ) to the rotary axis (5) of 2 degrees ≤ alpha ≤ 60 degrees and preferably 5 degrees ≤ alpha ≤ 25 degrees . The jet (7) is at an angle ( beta ) to the surface normals (15) of -60 degrees ≤ beta ≤ 60 degrees . The jet (7) lies on a first plane (E1) against the rotary axis (5), with a straight line intersecting the centre axis (9) of the jet (7) at an angle ( ) of 2 degrees ≤ delta ≤ 60 degrees and preferably 5 degrees ≤ delta ≤ 25 degrees . The jet has a diameter of 0.05-0.8 mm and preferably 0.1-0.4 mm.
