pli reading for determining and displaying the nip pressure profile at this location such a reading would be less than accurate as the sensing roll full rotates in a 360 u00b0 revolution accordingly the calculated nip pressure at this position will be less than accurate however the processing unit would display a nip pressure profile would appear to be accurate but in reality would be less than accurate if adjustments are made to the sensing roll by the machine operator or through automatic adjustment equipment to compensate for high or low pressure readings then the sensing roll could be adjusted to develop even more incorrect pressures at various locations in the nip region as the roll 10 rotates placing different sensors into the nip region the respective sensors measure the pressure which is then transmitted to the processing unit the processing unit associated with each sensing roll 10 can then calculate the average pressure of each pair of corresponding sensors at the various cross directional positions and produce a nip pressure profile which can be visualized on a monitor or other visual screen computer equipment well known in the art could be utilized to process the pressure readings that are being made in milliseconds one method of the present invention for sensing and removing the effects of rotational variability from the nip pressure profile of a.
