The focus of the development of PR Rolls fly rolls lay on achieving a reliable function and removing factors weakening paper quality.

Speed differences between rolls and the paper web deteriorate the spreading of the paper, create dust and weaken the quality of the end product. Due to the right bearing and lubrication solutions of PR Rolls fly rolls, speed differences and the problems caused by them are minimized.

A low-friction bearing system also prevents temperature differences and improves paper quality. At the same time, they increase the operating life and decrease the damaging risk of polymer roll coatings.

To optimize the spreading effect of the rolls PR Rolls chooses the most appropriate alternative for each operating condition from the coatings that have been developed by the company itself.

Post-lubrication of fly rolls is implemented during production via separate lubrication channels.
