Recent experiences with consistency profile control installations

This paper discusses recent experiences with consistency profile control in cluding its capabilities, limitations and practical considerations. Various criteria are applied to examine the performance of dilution control equipp ed headboxes compared to the performance of comparable headboxes with slice lip control. These criteria, including 2-sigma and peak-to-peak variation measurement, and streak distribution, are used to establish a benchmark for measuring actual performance of operating consistency and slice lip contro l systems. Finally, the paper concludes, with a discussion of future optimi zation opportunities made possible by consistency and slice lip control tec hnologies.
