Thermo rolls, calender rolls, roll shells

Thermo rolls

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."

Calender rolls

are used to produce paper. Even the slightes flaw in the surface of the roll (e.g. pores or cracks) must be absolutely excluded, in order to guarantee the best possible quality of the end product.

"The more precise the grinding of the calender rolls,

the lower the product tolerances."

Roll shells

are made of chilled cast iron, gray cast iron or forged steel, depending on the application and requirements.

"The more precisely the inner-Ø is honed,

the better the dimensional and shape accuracy of the roll shell."
