Thermo rolls, calender rolls, roll shells

are ground with the highest precision. This allows for the lowest possible thickness tolerances of the paper sheet. Thermal rolls feature lowest possible temperature deviations on the surface.


The more precise the grinding of the body, the higher the quality of the paper sheet.
