Roll concepts

Thermo rolls

Heated thermal calender rolls with peripheral bores for optimal heat transfer from Walzen Irle utilizing the well known flow principles MonoPass, DuoPass or TriPass can be found in all types of calenders, in hardnip calenders, in super- and softnip calenders as well as in offline or online operating multinip calenders.

 

Calender rolls

Conventional calender rolls are used in two- or multi-roll-calenders as unheated, solid poured with integral or bolted on journals. We manufacture replacement rolls with improvements in material and production.

 

Roll shells

We manufacture the shells for multi-zone rolls and swimming rolls in various materials such as chilled cast iron, the modified chrome cast iron material KSTV or hardened forged steel. For soft covered rolls the shells are normally made of grey iron or nodular iron.
