摘要： A sensor for detecting directional variations in a physical characteristic of a moving sheet of material is disclosed. The sensor has a support for supporting the moving sheet. The support defines an open region into which the moving sheet is deflected by a deflector. Detectors coupled to the support detect and produce signals indicative of the force exerted on the support by the deflected sheet in at least three different directions. Each signal is processed to determine a physical characteristic, such as extensional stiffness, of the sheet of material in each of the three directions. The directional variations of the physical characteristic may be used to determine the fiber orientation angle and the degree of anisotropism of the sheet.

摘要： A sensor for detecting directional variations in a physical characteristic of a moving sheet of material is disclosed. The sensor has a support for supporting the moving sheet. The support defines an open region into which the moving sheet is deflected by a deflector. The support is rotatable to allow detectors coupled to the support to detect and produce signals indicative of the force exerted on the support by the deflected sheet in a number of different directions. Each signal is processed to determine a physical characteristic, such as extensional stiffness, of the sheet of material in each direction. The directional variations of the physical characteristic may be used to determine the fiber orientation angle and the degree of anisotropism of the sheet.

摘要： A sensor is disclosed for sensing a physical property of a sheet material. The sensor includes a mechanism for supporting one side of the sheet along the periphery of a defined region and a mechanism for forcibly deflecting the sheet into the unsupported center of the defined region. A transducer may also be incorporated to sense the force required to deflect the sheet into the unsupported region and/or the distance that the sheet is deflected into the unsupported region. The sensor may be operatively coupled to a computer programmed to determine a physical property of the sheet based upon the sensed force and/or distance, such as the sheet failure strength.

摘要： A sheet tension measuring device is disclosed for measuring the tension of a moving sheet wherein a moving sheet is accurately positioned with pinchers at 2 spaced locations. The sheet is deflected between these pinchers from its nominal straight line path, and the amount of deflection and deflecting force are measured. The pinchers iron out any wrinkles in the sheet as the moving sheet slides through the pinchers. Sheet tension is computed based upon the measured deflection force and deflection distance. The resulting measurements of local sheet tension are used to correct nondestructive sheet strength measurements. A device and method are also disclosed for nondestructively determining the sheet strength and the extensional stiffness of the sheet in the machine direction and in the cross-direction.

摘要： A method for determining bending stiffness of a moving sheet using an on-line sheet bending stiffness sensor. The sensor continuously bends the sheet as it is being manufactured and, based upon the force required to bend the sheet, the amount of bending and the tension applied to the sheet, the sensor determines a parameter indicative of sheet bending stiffness. The resulting parameter can be correlated with conventional destructive laboratory tests of sheet bending stiffness.

摘要： An on-line laser triangulation position sensing system provides measurements of the surface features of a moving sheet such as paper. The measurements are correlatable with measurements made with standard laboratory surface smoothness testers and provide predictions of the printability of paper during its fabrication. The sensing system includes a segmented balance detector having a high frequency response. The sensing system further includes signal processing circuitry comprising a plurality of channels, each channel including a filter. The various filters have different cutoff frequencies for passing different frequency spectra representing ranges of surface feature scale sizes. The cutoff frequency of each filter is varied in response to variations in sheet speed. The sheet sensing system further includes a sheet stabilizer to minimize flutter in the measurement region and a standardizing member permitting performance verification of the sensor system at at least one scale size spectrum. The sensing system may also be provided with a sheet compressor to compress the sheet in the measurement region so as to simulate the pressures applied to sheet samples by laboratory air leak smoothness testers. The output of the position sensing system may be used in conjunction with various kinds of papermaking machines to control one or more of the many papermaking process parameters that determine the smoothness or texture of the final product. The sensing system can be used to measure tissue crepe and such measurement can be utilized to control various crepe-determining stages in a tissue making machine and to monitor the condition of the creping or doctor blade in such a machine.

摘要： A sensor and method is provided for measuring one or more select components of a material. In one embodiment, a method measures the components by emitting electromagnetic radiation at the material and detecting the intensity of the emerging radiation at separate locations from the source. In another embodiment, a sensor provides a radiation source for emitting radiation at a sheet, a plurality of detecting means, wherein at least one detecting means is offset from the source, for detecting radiation after interaction with the sheet and first and second reflectors for directing the radiation so that the radiation makes multiple interactions with the sheet when moving from the source to the detecting means. The invention can accurately measure the select components (e.g., moisture) of different grades of paper by eliminating the effects of the scattering power and determining absorption power at each band of the spectrum considered necessary for a particular measurement.
