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.
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 >>
iRoll portable technology can be used for:
With iRoll, we have made a huge step forward in improving the winding quality,” says Dustin Jeckstadt, Project Manager at Sappi Alfeld
In these exceptional times, remote services provide papermakers with quick and safe access to Valmet’s expertise. Intelligent roll remote support and data analysis services provide a tool for supporting onsite actions and maintenance, as well as optimizing the papermaking process.
Intelligent Roll Solutions will turn your roll into an intelligent service platform, providing a new way to analyze data and network globally. This data beyond the rolls can help you achieve your production targets for enhanced efficiency and cost savings.
To optimize press nip efficiency for TM 4, SsangYong turned to Valmet. The main targets were to improve energy efficiency by lowering steam consumption through higher post-press dryness, and to get more uniform moisture profiles by improving dryness profiles.
More even tension profiles cut winder wrinkling and reduce breaks and cull. Jumbo roll set count raised from two to four. Irving Paper has managed to improve its customer roll throughput and the hardness uniformity with the help of Valmet reel drum with integrated iRoll nip load and reel hardness profile measurement and control.
