摘要： A DOCTOR IS DISCLOSED HAVING A PIVOTABLE DOCTOR BACK PARALLEL TO AND SPACED FROM A ROLL OF A PAPER MAKING MACHINE. A BLADE CARRIED BY A BLADE HOLDER IS CONNECTED TO THE BACK BY RESILIENT MEANS COMPRISING A FIRST CANTILEVER CONNECTED TO THE DOCTOR BACK AND PROJECTING AWAY FROM THE ROLL, AND A SECOND CANTILEVER CONNECTED TO THE FREE END OF THE FIRST CANTILEVER WITH THE FREE END OF THE SECOND CANTILEVER PROJECTING TOWARD THE ROLL. THE SECOND CANTILEVER SUPPORTS ON THE FREE END THEREOF A BLAND HOLDING ASSEMBLY TO CARRY THE BLADE. TEH BLADE IS THUS CARRIED BY A DOUBLE CANTILEVERED RESILIENT MEANS FOR SUPPLEMENTING THE RESILIENCY OF THE BLADE FOR CONTOUR FOLLOWING ENGAGEMENT OF THE BLADE WITH THE ROLL.

摘要： A DOCTOR IS DISCLOSED HAVING A PIVOTABLE DOCTOR BACK PARALLEL TO AND SPACED FROM A ROLL OF A PAPER MAKING MACHINE. A BLADE CARRIED BY A BLADE HOLDER IS RESILIENTLY CONNECTED TO THE DOCTOR BACK BY A THIN PLATE OF SUBSTANTIAL WIDTH AND SUFFICIENT LENGTH RELATIVE TO ITS THICKNESS SO AS TO BE RESILIENT AND SUPPLEMENT THE RESILIENCY OF THE BLADE FOR IMPROVED CONTOUR FOLLOWING AND PRESSURIZED SCRAPING OF THE ROLL. THE THIN PLATE, MADE UP OF SEVERAL SEGMENTS ABUTTING EACH OTHER ALONG EDGES NORMAL TO THE ROLL, EXTENDS THE FULL WIDTH OF THE ROLL AND COVERS THE SPACE BETWEEN THE ROLL AND DOCTOR BACK. THE BLADE HOLDER COMPRISES SEGMENTS WHICH OVERLAP THE PLATE SEGMENT, WITH ADJACENT BLADE HOLDER SEGMENTS HELD IN ALIGNMENT FOR BLADE INSERTION AND REMOVAL, BY AN OVERLAPPED PLATE SEGMENT.

摘要： Vibration sensors can be used in paper making systems and methods to determine various aspects of the paper making operation. Vibration sensors, for example, positioned on cleaning blades configured to clean various deposits off of rollers in a paper making system can output vibration data that can be indicative of the vibration of the blade. The vibration data can be analyzed in order to characterize the cause of the vibration and/or the location of the vibration within a paper making system. If the vibration data satisfies a predetermined condition, a corrective action can be initiated. Different corrective actions can be initiated based on the characterized cause and/or location of the vibration in order to effectively improve the operation of the system while minimizing costly system shut downs and major maintenance.

摘要： The invention embodies the application of different combinations of the monitoring and data processing aspects as a means to develop an early warning chatter alarming system. Configuring an early warning chatter alarming system can be as simple as using nσ alarm settings to develop an alarming strategy from different trend conditions such as overall RMS, selected vibration frequencies, slope analysis, and wavelet analysis. A higher level of alarming is provided by using a time integrated approach to account for both intensity of the alarm variable and duration. Combining these different aspects with a predictive model incorporates process-operating conditions to enhance the alarming sensitivity for earlier detection and reduce false positives. Finally, combining the different alarming aspects with a rule-based decision making approach such as fuzzy logic allows alarming based on qualitative analysis of different data streams.
