The SMART technology has sensors embedded within the roll cover that measure the nip profile while the machine is operating. Through a wireless link, data is communicated from the sensors to a computer, which gives the nip profile in real time.

William Butterfield, Stowe Woodward vice-president, global rolls technology, explained how this allows operators to make immediate adjustments. The technology, he added, eliminates the need for shutdowns to take the nip profile, and also results in a lower cost per tonne, reduced consumption of raw materials and energy, and increased machine efficiency and product quality.

In addition, Butterfield pointed out the return on investment is not

measured in years, but in months – as “early as the first shutdown,” he said.
