SYSTEMS AND METHODS FOR PROVIDING IMPROVED DEWATERING PERFORMANCE IN A PAPERMAKING MACHINE

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(24) is coupled to a doctor blade holder(l?), and the doctor blade holder(l?) is coupled to a doctor-back (14 ). 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 (28) 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 (24) during movement of the moving surf ace (28).
