    摘要: Collecting data includes generating a sensor signal from each of a plurality of sensors located on a sensing roll, wherein each signal is generated when each sensor enters a region of a nip between the sensing roll and mating roll during each rotation of the sensing roll; wherein a web of material travels through the nip and a continuous band contacts a region of the web of material upstream from or at the nip. A periodically occurring starting reference is generated associated with each rotation of the continuous band and the signal generated by each sensor is received so that the one of the plurality of sensors which generated this signal is determined and one of a plurality of tracking segments associated with the continuous band is identified. The signal is stored to associate the respective sensor signal with the identified one tracking segment.

    摘要: Multiple groups of sensors are circumferentially spaced apart at each cross-directional position along a sensing roll of a nip press to measure and cancel or nearly cancel the effects of rotational variability which may be acting on the sensing roll. The strategically-placed sensors are designed to measure the pressure being placed against the web that is being advanced through the nip press. The average of the measurements of multiple sensors spaced circumferential apart provides a good cancellation of any rotational variability that might be found at a cross-directional position on the sensing roll. In this manner, a more true measurement of the nip pressure profile can be obtained and better adjustments made to reduce nip pressure profile variability. In addition, the nip variability profile may be used as a predictor of cover or bearing failures, resonant frequencies and other roll anomalies.
