摘要： PROBLEM TO BE SOLVED: To provide both an apparatus for rapidly controlling the basis weight of a paper produced in a papermaking machine and a method for the control.
SOLUTION: A principal part of a stock flows through a first line 55A controlled with a thick stock valve and then flows from a stock box 53 into a headbox 1. A secondary part of the stock is deflected through a second line 56A regulated by a second valve 56B. The thick stock valve is controlled by the basis weight in a dry part and the second valve 56B responds to measured values of the basis weight of the wet stock on a wire 7. The second line 56A and the control valve 56B form a close regulation loop at a quick response time together with the measured values of the basis weight in a wet part. On the other hand, the first line 55A and the control valve 55B responsive to the measured values of the basis weight in the dry part form a rough regulation loop.

摘要： A sensor imbedded rolle (40) for detecting changes in properties of a material and a measurement apparatus including a fixed impedance element coupled in series with a variable sensor imbedded roller (40) between an input signal and a reference potential is described. The sensor (41), which includes an electrode configuration, is embedded into a roller (40) such that when the roller rotates the sensor contacts the material being measured and the sensor's impedance varies. The variable impedance of the sensor relates to changes in property of the material being sensed which can then be related to changes in other physical characteristics of the material, such as weight, chemical composition, and temperature. Sensor imbedded rollers (40) can be placed in a sheetmaking machine to measure the pre-formed and post-formed paper product.

摘要： Significant improvements in papermaking control can be achieved by employing an array of sensors that are positioned underneath the wire of the machine to measure the conductivity of the aqueous wet stock. The conductivity of the wet stock is directly proportional to the total water weight within the wet stock; consequently, the sensor provides information which can be used to monitor and control the quality of the paper sheet produced. Because CD water weight profile is obtained practically instantaneously, the MD and CD variations are essentially decoupled. Quality improvements to the sheet fabricated will be achieved by providing fast control of the actuators on the machine and by tuning components on the machine to eliminate the sources of variations. Further, the dry stock weight of a sheet of wet stock that is resting on a water permeable moving wire of the papermaking machine can be made employing a water weight sensor element that is positioned adjacent to the wire and that generates signals indicative of the water weight of the sheet of wet stock on the wire. Moreover, the moisture level cross-direction (CD) profile of a sheet of material that is produced can also be measured.

摘要： System and method for producing paper that employ an apparatus for measuring electrical characteristics of a fibrous composition. The apparatus comprises a plurality of conductivity (or resistance) detectors (26) each comprising a sensor that is sensitive to the conductivity (or resistance) and the proximity of the material (e.g., fibrous composition) to the sensor. Measurements from the apparatus relate to the zeta potential of the fibrous materials in the composition. The zeta potential profiles corresponding optimized configurations of the sheetmaking process can be employed to monitor and control the process.

摘要： A system and method of providing fast machine direction (MD) and cross direction (CD) basis weight adjustments using a simultaneous multi-point water weight sensors (21, 22) which provides independent MD and CD measurements is described. The water weight sensors (21, 22) are placed under the wire (12) of the sheetmaking machine and provide fast wet end water weight measurements which are converted into predicted dry end basis weight information and used to control operating variables of machine elements in the sheetmaking machine to compensate for high frequency process variations. MD wet end measurements are used to control operating variables of machine elements that influence the MD dry end basis weight and CD wet end measurements are used to control operating variables of machine elements that influence CD dry end basis weight. The fast control information provided by the non-scanned water weight sensor can be used in a fast control loop which provides feedback information to wetstock source (10), headbox (11) and forming elements and which can be used with a slower response control loop including a dry end sensor which provides a slower basis weight measurement and which controls system variables to compensate for larger basis weight fluctuations.

摘要： Apparatus and process for controlling the basis weight of paper produced in a papermaking machine are provided. In the papermaking process, a major portion of the paper stock flows through a first line that is controlled by a thick stock valve and a minor portion of the stock flow from the stuff box to the headbox is diverted through a second line that is regulated by a second valve (e.g., vernier valve). The thick stock valve is controlled by the dry end basis weight and the second valve responsive to measurements of the basis weight of the wet stock at the wire. The second line and control valve along with the wet end basis weight measurements form a fine control loop with fast response time whereas the first line and control valve that is responsive to dry end basis weight measurements form a course control loop. The dual control loops enable fast and actual basis weight control.
