Valmet’s multinip calender is used both in off-line and on-line applications. The OptiCalender Multinip loading principle makes it possible to load all nips with the same linear load, resulting in efficient plasticization of paper in the very first nips. Profiling performance is affected by the number of control zones on deflection compensated bottom and top rolls.

High end-product quality
Wide range of process parameters gives more flexibility to produce different grades. The aimed quality level will be reached by combining the effect of temperature and linear load. It is possible to design the calender so that there is a space reservation to add rolls in the future. A partial nip mode is also a possibility.
Even profiles and desired surface quality can be reached with OptiCalender Multinip's accurate loading and even surface temperatures of thermo roll and stable temperature control of heating system. Also intermediate roll levers and profiling with deflection compensated rolls drives to high product quality.
Understanding the fundamentals behind functional spreading of paper web is demanding and requires a long experience.
Reliable operation and high efficiency
High time-efficiency is a combination of many factors. High quality and durable components ensure e.g. that spare parts are available also in the future and the roll covers are of top quality. Thermo roll dimensioning according to FKM norms, i.e. thermo rolls dimensioned to withstand the process parameters. Comprehensive monitoring of calender systems and equipment minimizes unplanned shut-downs.
High performance tail threading is a key element for high productivity of the paper machine. Valmet has a large numbers of on-line multinip calender tail threading in both Valmet’s own and competitors calenders. Tail threading performance is developed continuously by running trials in tail threading pilot machine.
In off-line calender efficient splicing is a must. Both unwind and wind-up splicing sequences are automatic.
Easy operation and safe maintenance
The multinip calenders are easy to access for maintenance. User-friendly automation provides real time info about the machine status. All information - including history – is easy to find. Functions are visualized symbols, whenever possible - No codes in error messages. User-friendly automation helps users recognize, diagnose, and recover from errors.
