Valmet iRoll

Valmet's iRoll product family is a complete set of tools for controlling paper tension and nip profiles. iRolls are now available for all main processes and positions in pulp, paper, board and tissue machines with the latest Valmet roll covers.

Thanks to good market feedback, Valmet is now expanding its iRoll manufacturing capability. By the end of June 2014, iRoll manufacturing will expand to cover Finland, France, the United States, Thailand and China. Valmet has also developed local field service competencies through an iRoll academy training program.

"After installing an iRoll, our customers have thanked us for 50% fewer wet end breaks per day, improved runnability, 100% longer grinding intervals and a 40% improvement in the coat weight 2-sigma value, just to name a few of the results iRoll has achieved," says Samppa Ahmaniemi, director of Roll Covers at Valmet.

Accurate online measurements

The main benefit of the iRoll technology is its accurate online profile measurement and process control opportunity in press, sizer, coater, reel and winder applications. Valmet's iRoll is the fastest and most sensitive online profile measurement tool in the industry.

In addition to nip load profile, iRoll also measures applicator rod load profile (sizer) and parent roll hardness profile (reel), as well as paper, board or tissue tension profiles in selected positions. iRoll can even be connected to the machine automation system for closed loop process control.

iRoll Portable is a quick, cost-effective process analysis and tuning tool that is based on dynamic nip profile or paper/fabric tension profile measurements. iRoll Portable provides rapid results as Valmet's experts can carry out an iRoll Portable analysis during shutdowns.
