Original Abstract Submitted
profile alignment with cross-correlation is employed to determine the alignment between two measured profiles taken at different locations along a sheet of material. aligning two profiles in sheet manufacturing is critical so that the coating weight on the sheet can be calculated. coat weight profile is calculated by subtracting the weight of the sheet prior to coating from the measured total weight of the coated sheet after coating. when profiles are not aligned correctly for this subtraction, the coat weight profile will be inaccurate and corrective control actions for apparent deviations in coat weight may be applied to the wrong part of the sheet and may result in poor quality. profile misalignments are monitored by repeatedly performing cross-correlation analysis as new measurement data becomes available. offset is tracked over time and displayed. automatic alerts are triggered when the offset deviates from zero and/or changes in value (within certain thresholds).
