摘要： An apparatus and method for obtaining fiber weight measurements in the wet end of a sheetmaking system and for verifying fiber weight measurements taken in the wet end of a sheetmaking system which includes a water weight sensor positioned beneath the wire in the wet end of the sheetmaking system for obtaining water weight measurements and load cells residing beneath the water weight sensor for weighing the wet end sensor and the wire with wetstock (total weight) and without wetstock (tare weight). In one embodiment, the water weight measurement and the tare weight measurement are subtracted from the total weight to obtain the fiber weight in the wetstock. In another embodiment, the water weight measurement is used to obtain an predicted fiber weight measurement and the determined fiber weight is used to verify the predicted fiber weight measurement and the accuracy of the water weight measurement device.

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 system and method that combine an array of fast under wire water weigh sensors with a scanning system provides an accurate measurement of the entire sheet down to 1 in. by 1 in. resolution. Because CD profiles are obtained instantaneously, MD and CD variations are completely decoupled, even if CD profiles are taken at longer intervals apart. The technique allows monitoring the basis weight of a sheet of material that is formed in a process that employs a de-watering machine that includes a water permeable moving fabric supporting wet stock and a dry end which technique includes the steps of: a) positioning an array of water weight sensor elements (array) underneath and adjacent to the fabric wherein the array is positioned in a cross direction to the moving fabric; b) positioning a scanning sensor at the dry end to measure the dry basis weight of the sheet of material; c) operating the machine and measuring the water weights of the sheet of material with the array and measuring the dry basis weight of the sheet of material with the scanning sensor at the dry end; d) developing a functional relationship between water weight of the sheet as measured by the array and the basis weight of the sheet which is formed after being substantially de-watered; end; and e) periodically, adjusting the functional relationship using readings from the scanning sensor to compensate for variations due to process parameters. The technique can further include the step of correlating positional readings of the scanning sensor with measurements from the corresponding element in the array to obtain separate calibration for each individual element of the array and step e comprises adjusting the functional relationship obtained in step d and the calibration obtained in to compensate for variations due to process parameters.

摘要： System and method for producing paper are provided. The system controls formation of wet stock comprising fibers on a moving water permeable wire of a de-watering machine that has a refiner that is subject to a variable load and a headbox having at least one slice, wherein each slice has an aperture through which wet stock is discharged at a stock jet speed onto the wire that is moving at a wire speed. A sheet of wet stock moving a speed develops on the wire. The system includes: a) at least two water weight sensors that are positioned adjacent to the wire wherein the at least two sensors are positioned at different locations in the direction of movement of the wire and upstream from a dry line which develops during operation of the machine and the sensors generate signals indicative of a water weight profile made up of a multiplicity of water weight measurements; and b) means for adjusting at least one of the stock jet speed, sheet speed, wire speed, or refiner load to cause the water weight profile to match a preselected or optimal water weight profile. Techniques for predicting the dry stock weight of wet stock on the wire can be employed to assess the effect of adjusting the operating parameters. In addition, employing two sensors placed in the machine direction, the sheet speed can be determined by measuring the water weigh profile of a segment of the sheet and the time required for the segment to travel from one sensor to the next.
