  • Patent number: 8337667
    Abstract: A doctoring system is disclosed for cleaning a moving surface in a papermaking machine, and the doctoring system includes a doctor blade and fluid assist system. The doctor blade is coupled to a doctor blade holder, and the doctor blade holder is coupled to a doctor-back. The fluid assist system is for providing a fluid under positive pressure that is higher than atmospheric pressure. The fluid is directed in a direction generally opposite a direction of movement of the moving surface such that fluid of high momentum is provided to impinge on water resident within the moving surface and adjacent a leading edge of the doctor blade during movement of the moving surface.

  • Patent number: 8337666
    Abstract: A doctoring system is disclosed for a papermaking machine wherein the doctoring system includes a doctor blade and a fluid assist means. The doctor blade is coupled to a doctor blade holder, and is for cleaning a moving surface. The doctor blade holder is coupled to a doctor-back. The fluid assist means is for providing a fluid under positive pressure that is higher than atmospheric pressure and is directed in a direction generally along a direction of movement of the moving surface such that a negative pressure that is lower than atmospheric pressure develops in a negative pressure zone adjacent the moving surface and a following surface of the doctor blade during movement of the moving surface.

  • Patent number: 6867155
    Abstract: A multiplayer composite doctor blade has a side edge configured for application to the surface of a rotating roll in a paper making machine. The doctor blade has an inner core and intermediate layers preferably enclosed by outer layers. The inner core is predominantly polymeric material. The intermediate layers on opposite sides of the core include reinforcing fibers. The side edge of the doctor blade has an abrasiveness as measured by ASTM test method D5181-91 of between about 4.0 to 5.0.

  • Patent number: 6786999
    Abstract: An apparatus for doctoring a roll surface including a pivot bar adapted to be mounted on a doctor back and which the pivot bar defines an upwardly projecting fulcrum. A first shelf projects forwardly beyond the fulcrum and a top plate pivotally supported on and projecting forwardly beyond the fulcrum overlies the first shelf. The top platen is held downwardly against the fulcrum. Blade support members are carried by and cooperate with the top plate to define forwardly open slots, which slots are configured and dimensioned to receive a rear edge of a forwardly projecting doctor blade. The blade support members have rearwardly projecting second shelves underlying the first shelf and a loading mechanism is interposed between the first and second shelves for pivoting the top plate on the fulcrum in a direction urging the doctor blade against the roll surface.

  • Patent number: 6524444
    Abstract: In a paper machine having a roll rotating about an axis extending in a cross machine direction, and having a doctor blade applied to the roll surface by a blade holder parallel to the axis and carried on a doctor back, an apparatus is provided for accommodating relative movement between the blade holder and the doctor back in the cross machine direction during mounting and removal of the blade holder. The apparatus comprises a rail fixed to the doctor back and extending longitudinally in the cross machine direction. A groove extends along the length of the guide rail. The groove has a bottom, a width measured between confronting sides, and a top defined by ledges projecting inwardly from the sides, with inner edges spaced one from the other to define a slot that underlies the blade holder and has a width narrower than the width of the groove. A plurality of shafts are spaced along the length of the blade holder and project downwardly through the slot and into the groove.
