摘要 |
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. |
