Calender rolls

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."
