  • Apparatus and method for correcting basis weight measurements using surface topology measurement data
    Patent number: 7959763
    Abstract: An apparatus and method for correcting an areal weight measurement of a stretchable web using surface topology measurement data is disclosed. Areal weight may comprise a basis weight or a water weight. The apparatus measures a surface of the stretchable web with a basis weight measuring device to obtain a rough basis weight measurement. The apparatus then measures the surface of the stretchable web with a surface topology measuring device to obtain surface topology measurement data. The apparatus comprises a controller that corrects the rough basis weight measurement of the stretchable web using surface topology measurement data. The corrected basis weight measurement may be used as a feedback value in a real time manufacturing process of the stretchable web.

  • Jet velocity vector profile measurement and control
    Patent number: 7399380
    Abstract: In a papermaking system having a headbox to dispense a jet of liquid and paper forming fibers, an improvement comprising at least one sensor arrangement for simultaneously or sequentially measuring in at least one location the jet velocity or jet flow correlation of the jet at plural known angles relative to the machine direction. The measured data is analyzed to generate a velocity vector profile or velocity direction profile of the jet, and hence to determine the profile of fiber orientation angles laid down in the sheet formed of the jet.
