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.
Our thermo rolls are made by cast iron and on the basis of cylinders
Manufactured according the requested specifications
The basis of our cylinder rolls are tubes.The materials are steel, stainless steel, aluminium or combinations.
The quality of the weld seam is an important component for the quality of the cylinder. Therefore, welding is one of the core competences for cylinder construction. We place great value on this. Our partners are certified companies.
We build in this range: heating and cooling rollers, laminating rollers, calendars, printing rollers and embossing rolls, et cetera.
Standard chilled cast rolls
The casting process for chilled cast iron and grey cast iron is using the static castic proces. The horizontal centrifugal casting is used for smaller rolls.

In this range we built: mixing rolls, thermo rolls, calender rolls, heating and cooling rolls, laminating rolls, printing rolls, refining rolls, flaking rolls, cracking rolls and embossing rolls.
