iRoll - intelligent roll solutions for tissue production

The fastest on-line profile measurement tool

Valmet iRoll technology improves production efficiency and product quality by assuring optimal runnability of tissue machines. Tissuemaker 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 tissue and nips

iRoll may be utilized on a covered roll in tissue production 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.

Implementations of iRoll

The iRoll intelligent roll system can be installed as a permanent nip load profile measurement tool, as a 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.

Temporary nip or process analysis tool iRoll portable technology

iRoll portable provides the benefits of iRoll technology as a quick to
use, low cost service by using temporarily installed sensors. iRoll portable
measures e.g. press nip profiles or tension profiles online during production,
to enable profiling response tests and find the sources of profile issues.

iRoll portable for temporary troubleshooting and process analysis purposes

iRoll portable technology can be used for:

Improving tension profile and solving runnability issues
Improving tissue quality and profile related troubleshooting
Measuring nip profiles for determining proper crowns
Tuning up winding/reeling recipes
Condition tests
Improving parent and customer roll hardness profiles
Press nips, reels, winders, fabric tension profiles

Valmet has improved paper, board and tissue machine performance and output of 500 Valmet iRoll and iRoll portable customers. Top production quality, 50% reduction in sheet breaks, improved profitability: see how this was achieved with Valmet iRoll.

The results from cooperation with Valmet has been satisfying in energy savings and machine speed increase. We are looking forward to continue the development further in order to improve the energy and production efficiency even further and to get more cost savings.”
