iRoll - intelligent roll solutions for board and paper making

The fastest on-line profile measurement tool

Valmet iRoll technology improves production efficiency and product quality by assuring optimal runnability of board and paper machines. Papermaker can obtain significant cost savings by improved nip profiles, parent roll hardness profiles and tension profiles as well as printer and converter satisfaction.

Profile variation reduced by 40%

80% less winding broke

50% reduction in sheet breaks

iRoll technology for controlling paper and nips

iRoll may be utilized on a covered roll in board and paper machines to expand the roll’s primary function to include use as a transducer for sensing cross-machine nip linear load or sheet properties such as tension and parent roll hardness profile.

iRoll can be connected to automation and data collection systems. It also has advanced tools for data analysis, drawing color maps and more. With up to 200 data points in the cross-machine direction, iRoll provides high resolution profile feedback. Data from iRoll is truly online as it is updated up to 10 profiles per second.

How does the iRoll work?

Measures and controls paper and board properties, not only nip properties
Removes skewness and other errors in nip load profiles
Improves sheet tension profiles and runnability of end product
Determines correct crowning for roll covers and exact timing for roll changes
Monitors condition and tuning of nip loading equipment
Online control of web tension and roll hardness profiles, replacing unreliable thickness profile scanners
Provides full-speed online profile measurement with high CD-resolution

Valmet's iRoll is the fastest and most sensitive on-line profile measurement tool in the industry. iRoll technology enables to improve production efficiency and product quality by assuring optimal runnability of paper and board products.

Implementations of iRoll

The iRoll intelligent roll system can be installed as a permanent nip load profile measurement tool, as permanent tension profile measurement tool, roll hardness profile measurement tool or as iRoll portable service. For permanent iRoll applications, it must be used in conjunction with a roll cover.

From timely to condition based-monitoring

Monitoring based on iRoll nip profiles, vibrations and optimization data are some examples where roll condition information is analyzed. This provides security for our customers that technical solutions and recommended upgrades are based on their actual needs and goals.
