PR Rolls new and modernized rolls are equipped with EasyRuncouplings that improve roll functioning, rotation sensitivity and operating life.
The tight and long-running PR Rolls spreader roll that is equipped with EasyRuncouplings can be used in the press section as well as in the slitter-winder.
EasyRun-solutions are also very heat resistant.
EasyRun Benefits

Modernization and Maintenance
The new modernization method of spreader rolls significantly improves the rolls’ moisture and heat resistance and ensures perfect functionality at even
higher speeds.
The modernization of existing rolls is always based on precise
measurement and condition analysis of the rolls.
The renewal of the bearings and the sealing and the replacement of the couplings with EasyRun make old rolls as good as new.
The right bearing system and lubrication prevent dusting and weakening of paper quality that are caused by speed differences. By reducing the friction of the bearings temperature differences of the shell are balanced and their deteriorating effect on product quality is
prevented.
Dynamic balancing of the roll shell decreases vibration levels
and prolongs the life-cycle of the roll.
Modernization can involve the following procedures:
- Renewal of bearings and sealing
- Replacement of couplings with EasyRun
- Inspection of bow and correction, if needed
- Renewal of damaged parts
- Maintenance of supports
- Change of end sealing
- Coating and balancing
