RollCal™ 2 is a fairly new system using the multipoint measurement principle enabling true measurement of roll roundness.
As paper machines´ production speeds have edged towards 2,000 m / min ( approx. 6,500 ft / min.) the roll geometry and overall condition deserve careful consideration.
RollCal™ 2 has been developed from RollCal™ but it provides additionally several new features.
The four-point measurement technique that RollCal™ 2 utilises True Out-of-Roundness™ measurement capability, which measuring the roll roundness always in the correct way. This is not the case with two-point roll measurement systems in spite of are they new, old or automated applications.
The optimised out-of-roundness of a workpiece and its impact on the paper making process have become critical factors especially in a certain roll positions. A good number of customers have been using RollCal™ 2 system for a few years and have proved that the improved measurement is needed ( See also RollControl™ i / 3D – Grinding ).
