Customer case:

Valmet IQ improves supercalender operation at Sappi Kirkniemi

Nov 30, 2018

Faced with end-of-life issues for the quality control systems of two off-machine supercalenders, Sappi’s Kirkniemi mill turned to Valmet for replacements. “We already had the Valmet IQ quality control system on PM3 for two years with good results and for super calendering it offered us the potential for good control as well as online quality verification, essential for the introduction of a new product in our manufacturing portfolio,” says Heikki Järvinen, Production Engineer.

Caliper and bulk play a crucial role in our new product from the supercalenders and the improved measurements from the Valmet scanner allow us to really see what affects the caliper and how to control it.”
