New calendering solutions are developed all the time

New solutions can be utilized in machine rebuilds and improvements to enhance the capacity and performance of old calenders. Condition tests and audits are effective ways to evaluate calender performance and identify potential issues. Based on the results and findings from these audits, a more extensive rebuild or improvement may be proposed. Calender improvements are often highly customized. Most improvement initiatives originate from customer issues, and solutions are developed based on their specific requirements. Valmet boasts excellent pilot facilities in Järvenpää, where calendering solutions can be tested, particularly in the case of quality-related upgrades.

Valmet Edge Cooling Device for soft roll

Edge cooling is provided for the end areas of the soft roll and is cooled with air jet nozzles. The mill air is filtered and used as cooling air. You can adjust the edge cooling width manually. Edge cooling protects the edge areas of the soft roll cover outside of the web from overheating. The roll surface temperature in the edge areas is monitored with IR sensors. By using IR sensors, the cooling can be activated only when it is needed.
