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： PROBLEM TO BE SOLVED: To provide a method and device for monitoring and adjusting base weight of a coating on a paper sheet which is moving, while it is coated on the sheet. SOLUTION: A paper sheet 12 which is not coated is drawn out through a supply part of a coating material 14 housed between a lining roll 16 and blade 18. An outlet slot 20 of the sheet 12 is formed between the roll 16 and an edge 22 adjoining the blade, thus, the thickness of a coating on the paper 12 just after coming out of the slot 20 is decided by a distance and pressure between the blade edge 22 and the roll 16. An infrared ray coating weight sensor 32 is used for measuring a coating material weight coated on the base paper sheet 12, and measures effect of infrared ray absorption by the sheet 12 caused by changes in the base weight and water content of the sheet 12 for automatic compensation.

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： 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： A comparison of the specular and diffused radiation reflected from a coating can be used in ratio to locate the gel point of the coating, and to monitor coating drying characteristics. This same system may be used to monitor the drying process of the coatings in a lab setting to characterize the drying process, optimize coating quality or optimize mill efficiency. A system implementing the Applicant's method uses a radiation source to illuminate a measurement location on the coating, and then provides a first and second radiation detectors to detect reflected radiation from the coating, originating from the radiation source. One of the radiation detectors is arranged to collect specular radiation. The second detector is arranged to collect only diffused radiation. The ratio of these two values represents information about the location of the gel point for the coating, and coating drying characteristics.

摘要： A system of providing on-line turbulence measurements in a papermaking machine. The measurements are used to perform on-line adjustments to turbulence-inducing and adjusting elements in the papermaking machine to optimize final sheet product quality. Turbulence measurements are obtained using water weight sensors (23) in the wet end of the papermaking machine, specifically, under wire water weight measurements. Water weight readings are correlated to turbulence intensity levels. A turbulence processing sensor (25) sorts accumulated water weight measurement readings into intensity level intervals to obtain turbulence measurements or a turbulence profile. The trubulence measurements or profile is provided to a machine element controller (26) which uses the measured turbulence information and target turbulence information to generate control signals. Water weight sensors can obtain independent machine direction (MD) and cross machine direction (CD) water weight measurements and consequently independent turbulence measurements can be determined so that turbulence can be controlled in both directions. Machine elements are controlled so that turbulence remains uniform across the CD and so that the MD turbulence profile is optimized to resemble a target profile.

摘要： Apparatus and process for controlling the basis weight of paper produced in a papermaking machine are provided. In papermaking, a major portion of paper stock flows through a first line 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 regulated by a second valve. The thick stock valve is controlled by the dry end basis weight and the second valve is 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 ti me whereas the first line and control valve that is responsive to dry end basis weight measuremen ts form a course control loop. The dual control loops enable fast and actual basis weight control.

摘要： A system and method for producing paper product from a wetstock solution using a sensor for sensing resistive impedance changes of the wetstock on the support web of the system. The resistive impedance changes are used to measure, for example, the water weight of the wetstock. The system includes a fixed impedance element coupled in series with a sensor portion between an input signal and ground. The sensor portion includes two electrodes with the wetstock passing between and in close proximity to the electrodes. The sensor exhibits a variable impedance resulting from changes in the physical characteristics of the wetstock. The fixed impedance element and the variable impedance of the sensor portion form a voltage divider network such that changes in impedance of the sensor portion result in voltage changes which are measured, converted to impedance changes of the wetstock, and related to water weight of the wetstock.
