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 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.
iRoll Press enables online nip profile measurement in press nips to assure optimal dewatering in the nip.
iRoll Sizer shows size press nip load and applicator rod profile online and enables coat weight profile improvement.
iRoll Tension profile measurement reveals the sheet runnability characteristics online and it can also be used on felts and wires.
iRoll Temperature online measurement for rolls and optimizing drying process
iRoll Reel provides parent roll hardness profile and online control.
iRoll Coater for better blade profiles and coating quality.
iRoll Winder monitors the end product quality and reveals winding issues such as discontinuities in the nip loading.
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.
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.
Valmet's remote support and analysis services connect papermakers to Valmet experts online, if they are using iRoll, roll condition monitoring or other Intelligent Roll Solutions. View case examples here >>
